99<P ALIGN="JUSTIFY">The water buffalo is an animal resource whose potential seems to have been barely recognized or examined outside of Asia. Throughout the world there are proponents and enthusiasts for the various breeds of cattle; the water buffalo, however, is not a cow and it has been neglected. Nevertheless, this symbol of Asian life and endurance has performed notably well in recent trials in such diverse places as the United States, Australia, Papua New Guinea, Trinidad, Costa Rica, Venezuela, and Brazil. In Italy and Egypt as well as Bulgaria and other Balkan states the water buffalo has been an important part of animal husbandry for centuries. In each of these places certain herds of water buffalo appear to have equaled or surpassed the local cattle in growth, environmental tolerance, health, and the production of meat and calves.</P>
101<P ALIGN="JUSTIFY">Although these are empirical observations lacking painstaking, detailed experimentation, they do seem to indicate that the water buffalo could become an important resource in tropical, subtropical, and warm temperate zones in developing and developed countries.</P>
103<P ALIGN="JUSTIFY">If this is the case, then it is clear that many countries should begin water buffalo research. Serious attention by scientists could help dispel the misperceptions and uncertainties surrounding the animal and encourage its true qualities to emerge.</P>
105<P ALIGN="JUSTIFY">This report describes the water buffalo's attributes as perceived by several animal scientists. It is designed to present the apparent strengths of buffaloes compared with those of cattle, to introduce researchers and administrators to the animal's potential, and to identify priorities for buffalo research and testing.</P>
107<P ALIGN="JUSTIFY">The panel that produced this report met at Gainesville, Florida, in July 1979. It was composed of leading water buffalo experts (particularly those from outside Asia who have directed the beginnings of water buffalo industries in their countries) and leading American animal scientists, many of whom are also familiar with the animal.</P>
109<P ALIGN="JUSTIFY">This report complements The Husbandry and Health of the Domestic Buffalo, edited by W. Ross Cockrill and published in 1974 by the Food and Agriculture Organization of the United Nations. Cockrill's 933-page book is a "bible" of water buffalo knowledge and provides details of breeds, world distribution, physiology, and an extensive bibliography.</P>
111<P ALIGN="JUSTIFY">The present report is an introduction to the water buffalo and its potential. It is written particularly for decision makers, as well as scholars or students, in the hope that it will stimulate their interest in the animal and thereby increase the appreciation of, and funding for, buffalo research. The report includes much empirical observation, largely from the panel members. Some of these observations may, in the long run, prove not to be universally applicable. Much benchmark information needs to be obtained.</P>
113<P ALIGN="JUSTIFY">Since its creation in 1971, the Advisory Committee on Technology Innovation (ACTI) has investigated innovative ways to use current technology and resources to help developing countries. Often this has meant taking a fresh look at some neglected and unappreciated plant or animal species. The committee assembles ad hoc panels of experts (usually incorporating both skeptics and proponents) to scrutinize the topics selected. The panel reports serve to draw attention to neglected, but promising, technologies and resources. (For a list of ACTI reports, see page 115.) ACTI reports are provided free to developing countries under funding by the Agency for International Development (AID).</P>
115<P ALIGN="JUSTIFY">Program costs for this study were provided by AID'S Office of Agriculture, Development Support Bureau, and staff support was provided by the Office of Science and Technology, Development Support Bureau.</P>
117<P ALIGN="JUSTIFY">The final draft of this report was edited and prepared for publication by F. R. Ruskin. Bibliographic editing was by Wendy D. White. Cover art was by Deborah Hanson.</P>

125  </Description>
128<P ALIGN="JUSTIFY">The domesticated water buffalo Bubalus bubalis numbers at least 130 million-one-ninth the number of cattle in the world. It is estimated that between 1961 and 1981 the world's buffalo population increased by 11 percent, keeping pace with the percentage increase in the cattle population.</P>
130<P ALIGN="JUSTIFY">Although there are some pedigreed water buffaloes, most are nondescript animals that have not been selected or bred for productivity. There are two general types-the Swamp buffalo and the River buffalo.</P>
132<P ALIGN="JUSTIFY">Swamp buffaloes are slate gray, droopy necked, and ox-like, with massive backswept horns that make them favorite subjects for postcards and wooden statuettes in the Far East. They are found from the Philippines to as far west as India. They wallow in any water or mud puddle they can find or make. Primarily employed as a work animal, the Swamp buffalo is also used for meat but almost never for milk production.</P>
134<P ALIGN="JUSTIFY">River buffaloes are found farther west, from India to Egypt and Europe. Usually black or dark gray, with tightly coiled or drooping straight horns, they prefer to wallow in clean water. River buffaloes produce much more milk than Swamp buffaloes. They are the dairy type of water buffalo. In India, River buffaloes play an important role in the rural economy as suppliers of milk and draft power. River buffaloes make up about 35 percent of India's milk animals (other than goats) but produce almost 70 percent of its milk. Buffalo butterfat is the major source of cooking oil (ghee) in some Asian countries, including India and Pakistan.</P>
136<P ALIGN="JUSTIFY">Although water buffaloes are bovine creatures that somewhat resemble cattle, they are genetically further removed from cattle than are the North American bison (improperly called buffalo) whose massive forequarters, shaggy mane, and small hindquarters are unlike those of cattle. While bison can be bred with cattle to produce hybrids,( This is not, however, very successful, the male progeny (at least of the F 1 generation) are sterile).there is no well-documented case of a mating between water buffalo and cattle that has produced progeny.</P>
138<P ALIGN="JUSTIFY">Parts of Asia and even Europe have depended on water buffaloes for centuries. Their crescent horns, coarse skin, wide muzzles, and low-carried heads are represented on seals struck 5,000 years ago in the Indus Valley, suggesting that the animal had already been domesticated in the area that is now India and Pakistan. Although buffaloes were in use in China 4,000 years ago, they are not mentioned in the literature or seen in the art of the ancient Egyptians, Romans, or Greeks, to whom they were apparently unknown. It was not until about 600 A.D. that Arabs brought the animal from Mesopotamia and began moving it westward into the Near East (modern Syria, Israel, and Turkey). Water buffaloes were later introduced to Europe by pilgrims and crusaders returning from the Holy Land in the Middle Ages. In Italy buffaloes adapted to the area of the Pontine Marshes southeast of Rome and the area south of Naples. They also became established in Hungary, Romania, Yugoslavia, Greece, and Bulgaria and have remained there ever since.</P>
140<P ALIGN="JUSTIFY">Villagers in medieval Egypt adopted the water buffalo, which has since become the most important domestic animal in modern Egypt. Indeed, during the last 50 years, their buffalo population has doubled to over 2 million head. The animals now supply Egypt with more meat-much of it in the form of tender "veal"-than any other domestic animal. They also provide milk, cooking oil, and cheese.</P>
142<P ALIGN="JUSTIFY">Other areas have capitalized on the water buffalo's promise only in very recent times. For instance, small lots of the animals brought to Brazil (from Italy, India, and elsewhere) during the last 84 years have reproduced so well that they now total about 400,000 head and are still increasing, especially in the lower Amazon region. Buffalo meat and milk are now sold widely in Amazon towns and villages; the meat sells for the same price as beef. Nearby countries have also become familiar with the water buffalo. Trinidad imported several breeds from India between 1905 and 1908, while Venezuela, Colombia, and Guyana have been importing them in recent decades. During the 1970s Costa Rica, Ecuador, Cayenne, Panama, Suriname, and Guyana introduced small herds. By 1979 the buffalo in Venezuela numbered more than 7,000 head.</P>
144<P ALIGN="JUSTIFY">Across the Pacific, the new nation of Papua New Guinea has found the water buffalo well suited to its difficult environment. For 9 years the government has attempted to run cattle on the Sepik and Ramu Plains on Papua New Guinea's north coast, where the temperatures are high and the forage of poor quality. But the cattle remain thin and underweight. In the 1960s animal scientists began evaluating water buffaloes already living in Papua New Guinea and, encouraged by the results, introduced additional buffaloes from Australia. These have performed remarkably well, producing greater numbers of calves and much more meat than the cattle in the region. The buffaloes appear to maintain appetite despite the heat and humidity, whereas cattle do not. The government of Papua New Guinea has since imported more water buffaloes and today has thriving herds totaling almost 3,500 head. </P>
146<P ALIGN="JUSTIFY">The United States has been slow to recognize the water buffalo's potential, but the first herd (50 head) ever imported for commercial farming arrived in February 1978.(Air-freighted from the wilds of Guam, the U.S. island possession on the western Pacific, by panel member Tony Leonards. Prior to that time (in 1974), four head of water buffalo were imported to the Department of Animal science' university of Florida, for study. The only other water buffaloes in North America were a few animals in zoos.) The humble water buffalo, normally considered fit only for the steamy rice fields of Asia, is now proving itself on farm fields in Florida and Louisiana. As a result, interest in the animal is on the rise in U.S. university and farm circles.  </P>
148<P ALIGN="JUSTIFY">From experience accumulated in Asia, Egypt, South America, Papua New Guinea, Australia, the United States, and elsewhere, animal scientists now perceive that many general impressions about the water buffalo are incorrect.  </P>
150<P ALIGN="JUSTIFY">For example, it is widely believed that the water buffalo is mean and vicious. Encyclopedias reinforce this perception, and in the Western world it is the prevalent impression of the animal. The truth is, however, that unless wounded or severely stressed, the domesticated water buffalo is one of the gentlest of all farm animals. Despite an intimidating appearance, it is more like a household pet-sociable, gentle, and serene. In rural Asia the care of water buffaloes is often fumed over to small boys and girls aged about four to nine. The children spend their days with their family's gentle buffalo, riding it to water, washing it down, waiting while it rolls and wallows, and then riding it to some source of forage, perhaps a grassy field or thicket. It is not uncommon to see a buffalo patiently feeding, with a young friend stretched prone on its broad gray back, asleep.  </P>
152<P ALIGN="JUSTIFY">Perhaps the notion about the viciousness of water buffaloes stems from confusing them with the mean-tempered African buffalo Syncerus caffer, actually a distant relative with which they will not interbreed and which is classified in a different genus.  </P>
154<P ALIGN="JUSTIFY">Ferocity is the most blatant misconception concerning the water buffalo, although other fallacies are widely reported as well.  </P>
156<P ALIGN="JUSTIFY">One generally held belief is that water buffaloes can be raised only near water. Actually, buffaloes love to wallow, but they grow and reproduce normally without it, although in hot climates they must have shade available.  </P>
158<P ALIGN="JUSTIFY">Another belief is that the water buffalo is exclusively a tropical animal. River-type buffaloes, however, have been used to pull snow plows during Bulgarian winters. They are found in Italy (over 100,000 head), Albania, Yugoslavia, Greece, Turkey, the Georgia and Azerbaijan areas of the Soviet Union (almost 500,000 head) and other temperate-zone regions as well. They are also found in cold, mountainous areas of Pakistan, Afghanistan, and Nepal.  </P>
160<P ALIGN="JUSTIFY"><center><img src="p04to05.png"></center><br>
161 World Distribution of Water Buffaloes</P>
163<P ALIGN="JUSTIFY">Yet another misconception is that the water buffalo is just a poor man's beast of burden. In addition to providing fine lean meat, buffaloes in fact provide rich milk. Mozzarella cheese, one of the most popular in Europe, comes from the buffaloes in Italy. Buffalo milk has a higher content of both butterfat and nonfat solids than cow's milk does. It therefore often brings higher prices than cow's milk. Throughout much of India it is in such demand that cow's milk is sometimes hard to sell.  </P>
165<P ALIGN="JUSTIFY">Many of the misconceptions generally held about buffaloes are based on little data and much prejudice. For instance, it is widely believed that water buffalo meat is tough and less desirable than beef. However, when the animals are raised for meat, buffalo steaks are lean, as tender as beef, and in appearance it is difficult to distinguish the two. In taste-preference tests at the University of Queensland, buffalo steaks were preferred over those from Angus and Hereford cattle. Tests conducted in Trinidad, Venezuela, the United States, and Malaysia produced similar results.  </P>
167<P ALIGN="JUSTIFY">Australia has shipped water buffalo meat to Hong Kong, the United States, Germany, and Scandinavia. Buffalo meat is now available in stores in Australia's Northern Territory, where demand exceeds supply. It sells at competitive prices and is particularly sought for barbecues and the famous Australian meat pie. In the Philippines, two-thirds of the meat consumed in homes and restaurants is actually water buffalo, a fact that many Filipinos do not realize.  </P>
169<P ALIGN="JUSTIFY">Compared with cattle,waterbuffaloes apparently have an efficient digestive system, one which extracts nourishment from forage so coarse and poor that cattle do not thrive on it. Thin cattle are commonly seen in Asia and northern Australia, for example, but it's rare to see a protruding rib on a buffalo, even though it uses the same source of feed.  </P>
171<P ALIGN="JUSTIFY">In Asia, the Middle East, and Europe, water buffaloes live on coarse vegetation on the marginal land traditionally left to the peasants. They help make human survival possible. An old Chinese woman in Taiwan once told panelist W. Ross Cockrill: "To my family the buffalo is more important than I am. When I die, they'll weep for me; but if our buffalo dies, they may starve."  </P>
173<P ALIGN="JUSTIFY">A better understanding of the water buffalo could be invaluable to many developing nations. In particular, improved production of water buffalo meat offers hope for helping feed India, the second most populous nation on earth. Although India for religious reasons forbids the slaughter of cows, it has no prohibitions regarding slaughter of water buffaloes or the consumption of buffalo meat.  </P>
175<P ALIGN="JUSTIFY">Most developing countries are in the tropics, and the water buffalo is inherently a tropical animal. It is comfortable in hot, humid environments. In the Amazon, for example, buffaloes are now common on the landscape and may even replace cattle completely.  </P>
177<P ALIGN="JUSTIFY">Tropical countries have more serious disease problems than temperate countries do. Although susceptible to most cattle diseases, the water buffalo seems to resist ticks and often appears to be more resistant to some of the most devastating plagues that make cattle raising risky, difficult, and sometimes impossible in the tropics. Several researchers report that when water buffaloes are allowed to wallow, their mud-coated skin seems to deter insect and tick ectoparasites and they consequently require greatly reduced treatment with insecticides. Although the buffalo fly (Siphona exigua) affects the animals, other pests such as the warble fly and the screwworm, for example, seldom affect healthy buffaloes. AIso, despite their inclination for living in swamps, Avers, and ponds, diseases of the feet such as foot rot and foot abscesses are rare.  </P>
179<P ALIGN="JUSTIFY">Another benefit to developing countries is the water buffalo's legendary strength. A large part of the total farm power available in South China, Thailand, Indonesia, the Philippines, the Indochina states, India, and Pakistan comes from this "living tractor." Dependable and docile, the animals pull plows, harrows, and carts with loads that weigh several tons. In the Amazon buffalo teams pull boats laden with cargo and tourists through shallows and swamps.  </P>
181<P ALIGN="JUSTIFY">The petroleum crisis has forced many farmers to reconsider animal power even in some of the technically advanced countries. Buffaloes are not only extraordinarily strong, they can also work in deep mud that may bog down a tractor. Even up to their bellies they forge on, dragging both plow and driver through the mud. Although its average walking speed is only about 3 kilometers per hour, the buffalo, unlike its mechanical competition, doesn't need gasoline or spare parts and its working life is often 20 years or more.  </P>
183<P ALIGN="JUSTIFY">&nbsp;</P>
184<P ALIGN="JUSTIFY">Breeds</P>
186<P ALIGN="JUSTIFY">As already noted, the major genetic divisions of the water buffalo are the Swamp buffalo of the eastern half of Asia, which has swept-back horns, and the River buffalo of the western half of Asia, which usually has curled horns. There is also the Mediterranean buffalo, which is of the River type but has been isolated for so long that it has developed some unique characteristics. (Records of the buffalo in Italy date back 1,000 years, during which there have been no reported imports.) Mediterranean buffaloes are stocky, high yielding animals that combine both beef and dairy characteristics.  </P>
188<P ALIGN="JUSTIFY">Although there is only one breed of Swamp buffalo, certain subgroups seem to have specific inherited characteristics. For example, the buffaloes of Thailand are noted for their large size, averaging 450-550 kg, and weights of up to 1,000 kg have been observed. Elsewhere, Swamp buffaloes range from 250 kg for some small animals in China to 300 kg in Burma and 500-600 kg in Laos.  </P>
190<P ALIGN="JUSTIFY">Only in India and Pakistan are there well-defined breeds with standard qualities. There are eighteen River buffalo breeds in South Asia, which are further classified into five major groups designated as the Murrah, Gujarat, Uttar  Pradesh, Central Indian, and South Indian breeds. These are the five groups and  main breeds:  </P>

226<P ALIGN="JUSTIFY">The best-known breeds are Murrah, Nili/Ravl, Jafarabadi, Surti, Mehsana, and  Nagpuri. Most of the buffaloes of the Indian subcontinent belong to a nondescript  group known as the Desi buffalo. There is no controlled breeding among these  animals and most are quite small, yield little milk, and are variable in color.  </P>
228<P ALIGN="JUSTIFY">&nbsp;</P>
229<P ALIGN="JUSTIFY">Genetics</P>
231<P ALIGN="JUSTIFY">The Swamp buffalo has 48 chromosomes, the River buffalo, 50. The chromosomal  material is, however, similar in the two types and they crossbreed to produce fertile  hybrid progeny. Cattle, however, have 60 chromosomes and although mating  between cattle and buffaloes is common, hybrids from the union are unlikely to  occur.( In 1965 a reputed hybrid was born at Askaniya Nova Zoopark in the Soviet Union  (see Gray, A., 1971. Mammalian Hybrids, Commonwealth Agricultural Bureaux,  Slough, England, p. 126). Hybrids have also been reported from China (Van  Fu-Czao 1959, Gibridy buivolc i krupnogo  i rogatogo skota(buffalo and  cattlehybrids)Zhivotnovodstro, Mosk., 21:92). Both of these reports seem doubtful  because despite many attempts, no other hybrids have ever been claimed to have  been produced). </P>
233<P ALIGN="JUSTIFY">Individual buffaloes show large variation in milk yield, conformation, horn shape,  color, meat production, temperament, growth rate, and other characteristics.  Selection for survival under adverse conditions has occurred naturally (those that  could not stand adversity died early) and farmers have probably tended to select  animals of gentle temperament. But systematic genetic improvement has almost  never been attempted. It seems likely that further selection could quickly improve  their productivity.  </P>
235<P ALIGN="JUSTIFY">Unfortunately, the large bulls that would be best for breeding purposes are often  being selected as draft animals and castrated, or sent to slaughter, or (as with  some feral animals in northern Australia and on the Amazon island of Marajo) shot  by hunters. The result is that the buffalo's overall size in countries such as Thailand  and Indonesia has been decreasing as the genes for large size and fast growth are  lost.  </P>
237<P ALIGN="JUSTIFY">&nbsp;</P>
238<P ALIGN="JUSTIFY">Limitations  </P>
240<P ALIGN="JUSTIFY">The buffalo is still largely an animal of the village, and many of its reported  limitations are caused more by its environment than by the animal itself. Moreover,  much of the animal's genetic potential is obscured by environmental influences. For  example, for many breeds and types the genetic variations in milk yield and growth  cannot be accurately determined because they are overwhelmed by the effects of  inadequate nutrition and management.  </P>
242<P ALIGN="JUSTIFY">Nevertheless, some inherent limitations of buffaloes can be identified. For instance,  buffaloes suffer if forced to remain, even for a few hours, in direct sunlight. They  have only one-tenth the density of sweat glands of cattle and their coating of hair is  correspondingly sparse, providing little protection from the sun. Accordingly,  buffaloes must not be driven over long distances in the heat of the day. They must  be allowed time for watering and, if possible, for wallowing. Driving under a hot sun  for long hours will cause heat exhaustion and possibly death; losses can be very  high and can occur suddenly. Young calves are particularly affected by heat.  </P>
244<P ALIGN="JUSTIFY">Buffaloes are also sensitive to extreme cold and seem less able than cattle to  adapt to truly cold climates(A rule of thumb is that buffaloes don't do well where the sun is inadequate to ripen,  say, cotton, grapes, or Ace. Kaleff, B., 1942. Der Hausbuffel und seine  Zuchtungsbiologie im Vergleich zum Rind. Zeitschsift Tierzucht Biologze,  51:131-178). Sudden drops in temperature and chill winds may lead  to pneumonia and death.  </P>
246<P ALIGN="JUSTIFY">The water buffalo is usually found m areas where there is ready access to a wallow  or shower. This is not a necessity, but when temperatures are high the availability of  water is important for maintaining buffalo health and productivity. It seems clear,  then, that the buffalo is not suitable for arid lands.  </P>
248<P ALIGN="JUSTIFY">Increasing buffalo productivity through breed improvement is just now beginning.  Throughout Asia buffalo mating is almost completely haphazard, and so the animal  lacks the quality improvement through breeding that most cattle have had.  Therefore, most buffaloes are of nondescript heritage and genetic potential.  </P>
250<P ALIGN="JUSTIFY">On poor quality feed water buffalo grow at least as well as cattle, but under intensive  conditions they probably won't grow as fast as the best breeds of cattle. In feedlots,  therefore, the buffalo is likely to be less productive than improved cattle. Weight  gains of about 1 kg per day have been recorded, some exceptional cattle may gain  at almost twice that rate.  </P>
252<P ALIGN="JUSTIFY">The buffalo has long been considered a poor breeder-slow to mature sexually,  and slow to rebreed after calving. Accumulated experience now shows, however,  that this is mainly a result of poor management and nutrition. Buffaloes are not  sluggish breeders. Nevertheless, their gestation period is about a month longer  than that of cows, buffalo estrus is difficult to detect, and many matings occur~at  night so that~ farmers are likely to encounter more problems breeding buffaloes  than cattle.  </P>
254<P ALIGN="JUSTIFY">Buffaloes are gentle creatures, but if roughly or inexpertly handled they can, through fear or pain, become completely unmanageable. Buffalo behavior sometimes differs from that of cattle. For example, most buffaloes are not trained to be driven. Instead, the herdsman must walk alongside or ahead of them; they then instinctively follow. Also, because of their innate attachment to an individual site or herd it is more difficult to move buffaloes to new locations or herds. In addition, buffaloes respect fences less than cattle do and when they have the desire to move they are harder to contain. (Electric fences, however, will stop them.)  </P>
256<P ALIGN="JUSTIFY">Despite their general good health, buffaloes are probably as susceptible as cattle to most infections. However, the buffalo seems to be peculiarly sensitive to a few cattle diseases and resistant to a few others (see chapter 7). Reactions to some diseases seem to vary with region, environment, and breed, and the differences are not well understood.  </P>
258<P ALIGN="JUSTIFY">Destruction of the environment is sometimes attributed to buffalo wallowing. This danger seems to have been overstated, except in cases where stocking rates were unreasonably high.(An ongoing study in Northern Australia of environmental degradation widely attributed to buffalo has now shown that the effects are caused by man and climatic changes and only very slightly by buffaloes. (information supplied by D. G. Tulloch.) ) However, buffaloes rub against trees more often than cattle do, and they sometimes de-bark the trees, causing them to die.  </P>
260<P ALIGN="JUSTIFY">Unfortunately, some of the best genetic stocks of water buffaloes exist in areas where certain infections and viral and other diseases sometimes occur. Thus, many countries are reluctant to permit importation of water buffaloes, despite the fact that modern quarantine procedures under conditions of maximum security can essentially eliminate the risk.  </P>
262<P ALIGN="JUSTIFY">Finally, it must be emphasized that because buffalo research has been largely neglected, most results reported in this and other buffalo writings cover small numbers of animals and short periods of time. Many are merely empirical observations that have not been subjected to independent confirmation.  </P>

345  </Description>
348<P ALIGN="JUSTIFY">The water buffalo offers promise as a major source of meat, and the production of buffaloes solely for meat is now expanding.  </P>
350<P ALIGN="JUSTIFY">Because buffaloes have been used as draft animals for centuries, they have evolved with exceptional muscular development, some weigh 1,000 kg or more. Until recently, however, little thought was given to using them exclusively for meat production. Most buffalo meat was, and still is, derived from old animals slaughtered at the end of their productive life as work or milk animals. As a result, much of the buffalo meat sold is of poor quality. But when buffaloes are properly reared and fed, their meat is tender and palatable.  </P>
352<P ALIGN="JUSTIFY">Water buffaloes are exported for slaughter from India and Pakistan to the Middle East and from Thailand and Australia to Hong Kong. Demand for meat is so great that Thailand's buffalo population has dropped from 7 million to 5.7 million head in the last 20 years, a period in which the human population has more than doubled.  </P>
354<P ALIGN="JUSTIFY">&nbsp;</P>
355<P ALIGN="JUSTIFY">Carcass Characteristics</P>
357<P ALIGN="JUSTIFY">All buffalo breeds-even the milking ones-produce heavy animals whose carcass characteristics are similar to those of cattle.  </P>
359<P ALIGN="JUSTIFY">Despite heavier hide and head, the amount of useful meat (dressing percentage) from buffaloes is almost the same as in cattle. Mediterranean type buffalo and Zebu cattle steers in Brazil yielded dressing percentages of 55.5 and 56.6 percent respectively. Swamp buffalo dressing percentages have been measured in Australia at 53 percent. </P>
361<P ALIGN="JUSTIFY">Buffaloes are lean animals. Although a layer of subcutaneous fat covers the carcass, it is usually thinner than that on comparably fed cattle. Even animals that appear to be fat prove to be largely muscle. Australian research on Swamp buffaloes reveals that buffaloes with more than 25 percent fat are difficult to produce, whereas average choice-grade beef carcasses may contain  </P>
363<P ALIGN="JUSTIFY">In general, the buffalo carcass has rounder ribs, a higher proportion of muscle, and a lower proportion of bone and fat than beef has.  </P>
365<P ALIGN="JUSTIFY">Buffalo hide is so thick that it can be sliced into two or three layers before tanning into leather.  </P>
367<P ALIGN="JUSTIFY">&nbsp;</P>
368<P ALIGN="JUSTIFY">Meat Quality</P>
370<P ALIGN="JUSTIFY">Buffalo meat and beef are basically similar. The muscle pH (5.4), shrinkage on chilling (2 percent), moisture (76.6 percent), protein (19 percent), and ash (1 percent) are all about the same in buffalo meat and beef. Buffalo fat, however, is always white and buffalo meat is darker in color than beef because of more pigmentation or less intramuscular fat (2-3 percent "marbling," compared with the 3-4 percent in beef).  </P>
372<P ALIGN="JUSTIFY">&nbsp;</P>
373<P ALIGN="JUSTIFY">Eating Quality</P>
375<P ALIGN="JUSTIFY">Taste-panel tests and tenderness measurements conducted by research teams in a number of countries have shown that the meat of the water buffalo is as acceptable as that of cattle. Buffalo steaks have rated higher than beefsteaks in some taste tests in Australia, Malaysia, Venezuela, and Trinidad.  </P>
377<P ALIGN="JUSTIFY">In taste-panel studies in Trinidad, cooked joints from three carcasses Trinidad buffalo, a crossbred steer (Jamaica-Red/Sahiwal), and an imported carcass of a top-grade European beef steer-were served. The 28 diners all had experience in beef production, butchery, or catering and were not told the sources of the various joints. All the carcasses were held in cold storage for one week before cooking. The buffalo meat was rated highest by 14 judges; 7 chose the European beef; 5 thought the crossbred beef the best; and 2 said that the buffalo and crossbred were equal to or better than the European beef. The buffalo meat received most points for color (both meat and fat), taste, and general acceptability. There was little difference noted in texture.( Information supplied by P. N. Wilson.)</P>
379<P ALIGN="JUSTIFY">Buffalo veal is considered a delicacy. Calves are usually slaughtered for veal between 3 and 4 weeks of age; dressed weight is 59-66 percent of live weight.  </P>
381<P ALIGN="JUSTIFY">There is some evidence that buffaloes may retain meat tenderness to a more advanced age than cattle because the connective tissue hardens at a later age or because the diameter of muscle fibers in the buffalo increases more slowly than in cattle(Joksimonc, 1979) In one test the tenderness (measured by shearing force) of muscle samples from carcasses of buffalo steers 16-30 months old was the same as that from feedlot Angus, Hereford, and Friesian steers 12-18 months old. This gives farmers more flexibility in meeting fluctuating markets while still providing tender meat.  </P>

431    <Metadata name="Title">3 Milk</Metadata>
432  </Description>
435<P ALIGN="JUSTIFY">More than 5 percent of the world's milk comes from water buffaloes. Buffalo milk is  used in much the same way as cow's milk. It is high in fat and total solids, which  gives it a rich flavor. Many people prefer it to cow's milk and are willing to pay more  for it. In Egypt, for example, the severe mortality rate among buffalo calves is due in  part to the sale of buffalo milk, which is in high demand, thus depriving calves of  proper nourishment. This also occurs in India, where in the Bombay area alone an  estimated 10,000 newborn calves starve to death each year through lack of milk.  The demand for buffalo milk in India (about 60 percent of the milk consumed; over  80 percent in some states) is reflected in the prices paid for a liter of milk: about  130 paisa for cow's milk compared with about 200 paisa for buffalo milk.  </P>
437<P ALIGN="JUSTIFY">Twelve of the 18 major breeds of water buffalo are kept primarily for milk production  (although males may be used for traction and all animals are eventually used for  meat). The main milk breeds of India and Pakistan are the Murrah, Nili/Ravi, Surti,  Mehsana, Nagpuri, and Jafarabadi. The buffaloes of Egypt, Eastern Europe  (Bulgaria, Romania, Yugoslavia, and the USSR), and Italy are used for milk  production and there are also herds used principally for this purpose in Iran, Iraq,  and Turkey.  </P>
439<P ALIGN="JUSTIFY">&nbsp;</P>
440<P ALIGN="JUSTIFY">Composition</P>
442<P ALIGN="JUSTIFY">Buffalo milk contains less water, more total solids, more fat, slightly more lactose,  and more protein than cow's milk. It seems thicker than cow's milk because it  generally contains more than 16 percent total solids compared with 12-14 percent  for cow's milk. In addition, its fat content is usually 50-60 percent higher (or more)  than that of cow's milk. Although the butterfat content is usually 6-8 percent,( An analysis of 7,770 records of Nili/Ravi buffaloes in herds at the Pakistan  Research Institute showed that average butterfat content was 6.40 (a mean based  on 10 tests over 10 months). of all the samples tested, 77 percent ranged between  5 and 8 percent butterfat and 12 percent were below 5 percent butterfat.  -information supplied by R. E. McDowell.)  it can  go much higher in the milk of some well fed dairy buffaloes and in the milk of  Swamp buffaloes (which are not normally used for milking). Cow's milk butterfat content is usually between 3 and 5 percent.  </P>
444<P ALIGN="JUSTIFY">Because of its high butterfat content, buffalo milk has considerably higher energy value than cow's milk. Phospholipids are lower but cholesterol and saturated fatty acids are higher in buffalo milk. Studies have shown that digestibility is not adversely affected by this. Because of the high fat content, the buffalo's total fat yield per lactation compares favorably with that of improved breeds of dairy cattle; it is much higher than that of indigenous cows.  </P>
446<P ALIGN="JUSTIFY">Normally the protein in buffalo milk contains more casein and slightly more albumin and globulin than cow's milk. Several researchers have claimed that the biological value of buffalo milk protein is higher than that of cow's milk, but this has not yet been proved conclusively.  </P>
448<P ALIGN="JUSTIFY"><center><img src="p27.png"></center><br>
449 Tables 1 and 2</P>
451<P ALIGN="JUSTIFY">The mineral content of buffalo milk is nearly the same as that of cow's milk except for phosphorus, which occurs in roughly twice the amount in buffalo milk. Buffalo milk tends to be lower in salt.  </P>
453<P ALIGN="JUSTIFY">Buffalo milk lacks the yellow pigment carotene, precursor for vitamin A, and its whiteness is frequently used to differentiate it from cow's milk in the market. Despite the absence of carotene, the vitamin A content in buffalo milk is almost as high as that of cow's milk. (Apparently the buffalo converts the carotene in its diet to vitamin A. The two milks are similar in B complex vitamins and vitamin C, but buffalo milk tends to be lower in riboflavin.)  </P>
455<P ALIGN="JUSTIFY">&nbsp;</P>
456<P ALIGN="JUSTIFY">Milk Products</P>
458<P ALIGN="JUSTIFY">Buffalo milk, like cow's milk, can provide a wide variety of products: butter, butter oil (clarified butter or ghee), soft and hard cheeses, condensed or evaporated milks, ice cream,yogurt, and buttermilk. It is of great economic importance in India in preparing "toned" milk-a mixture of buffalo milk and milk made by reconstituting skim milk powder.  </P>
460<P ALIGN="JUSTIFY">The richness of buffalo milk makes it highly suitable for processing. To produce 1 kg of cheese, a cheese maker requires 8 kg of cow's milk but only 5 kg of buffalo milk. To produce 1 kg of butter requires 14 kg of cow's milk but only 10 kg of buffalo milk. Because of these high yields, processors appreciate the value of buffalo milk.  </P>
462<P ALIGN="JUSTIFY">Buffalo cheese is pure white. It many countries it is among the most desirable cheeses (mozzarella and ricotta in Italy, gemir in Iraq, the salty cheeses of Egypt, and pecorino in Bulgaria, for example). In Venezuela all the cheese produced from the small La Guanota milking herd in the Apure River basin (about 100 kg a day) is bought by the Hilton Hotel and sells for 15 bolivars per kg compared with 8 bolivars per kg for cheese made from cow's milk.  </P>
464<P ALIGN="JUSTIFY">Although much in demand for making soft cheese, buffalo milk is less desirable for making hard cheeses such as cheddar or gouda. During cheesemaking it produces acid more slowly than cow's milk, retains more water in the curd, and loses more fat in the whey.  </P>
466<P ALIGN="JUSTIFY">Cheeses are becoming increasingly popular throughout the world. Demand is rising at a rate that is among the highest for any food product. Cheese offers particular benefit to areas where refrigeration is not widely available, where transporting high-protein foods to remote areas is difficult, and where seasonal fluctuations affect milk supplies. Buffalo milk may make cheesemaking profitable on an even smaller scale than conventional dairying; it is more concentrated than cow's milk and requires relatively less energy to transport and process (an increasingly important factor where fuels are limited).  </P>

469 Table 3 Highest Milk Yield (kg per Day) Recorded in the All India Milk Yield</P>
471<P ALIGN="JUSTIFY">&nbsp;</P>
472<P ALIGN="JUSTIFY">Yield</P>
474<P ALIGN="JUSTIFY">In countries like India and Egypt, the milk yield of buffaloes is generally higher  (680-800 kg) than for local cattle (360-500 kg). However, since selection for  exceptional milk production is not conducted systematically, large variations in yield  occur between individual animals, and milk production of dairy buffaloes falls short  of its potential.  </P>
476<P ALIGN="JUSTIFY">Nonetheless, some outstanding yields have been recorded. On Indian government  farms, average yields for milking buffaloes range from 4 to 7 kg per day in  lactations averaging 285 days. Daily yields of 12 kg have been reported for some  Bulgarian buffalo cows and a daily production of over 20 kg has been reported for  some remarkable animals in India. A peak milk yield of 31.5 kg in a day has been  recorded from a champion Murrah buffalo in the All India Milk Yield Competition  conducted by the Government of India (see Table 3).  </P>
478<P ALIGN="JUSTIFY">At Caserta, Italy, a herd of 1,600 machine-milked, pedigreed dairy buffaloes has  produced average yields of 1,500 kg during lactations of 270 days. In Pakistan an  analysis of over 6,000 lactations of Nili/Ravi buffalo cows showed an average yield  of 1,925 kg during lactations averaging 282 days(Average adjusted for year and  season and calving. Cady et al., in press.) . In India the average milks yield of  Murrah buffaloes in established herds is also reported to be about  1,800kg(*"Williamson and Payne, 1965.)Table 4 lists some outstanding lactation  yields reported from different parts of the world. </P>
480<P ALIGN="JUSTIFY">As with cattle, the percentages of fat, protein, and total solids decrease as the milks yield increases.  </P>
482<P ALIGN="JUSTIFY">The Swamp buffaloes of Southeast Asia are usually considered poor milk producers. They are used mainly as draft animals, but it may be that their milk potential has been underestimated. In the Philippines Swamp buffalo cows with nursing calves have produced 300-800 kg of milk during lactation periods of 180-300 days(*Philippines Council for Agriculture and Resources Research (PCARR). 1978. The Philippines Recommends for Caraboo Production, PCARR, Los Banos, Philippines)In Thailand Swamp buffaloes selected and reared for milk production have yielded 3-5 kg per day during 305-day lactations.(Information supplied by Charan Chantalakhana.)</P>

487<P ALIGN="JUSTIFY">The Nanning Livestock Research Institute and Farm in Kwangsi Province,which is representative of many others in South China, is upgrading the native  Swamp buffaloes (or Shui Niu) by selective breeding for size and weight and by  crossbreeding with dairy breeds such as the Murrah and Nili/Ravi. The crossbreeds  that are milked yield 4-5 kg daily.(*CockriH, W. R. 1976. The Buffaloes of China.  FAO, Rome.) </P>

492<P ALIGN="JUSTIFY">The characteristics of the dairy buffalo so closely approximate those of the dairy cow that successful methods of breeding, husbandry, and feeding for  milks production for the cow can be applied equally to the dairy buffalo. Buffaloes,  however, have not been bred for uniform udders and it is more difficult to milk them  by machine.(Some thousands of buffaloes are machine milked in Bulgaria and Italy, however. At  Ain Shams University in Egypt, buffaloes have adapted to machine milking. The  calves are separated from their dams immediately after birth and no problems of  milk letdown have been observed. -information supplied by M. El Ashry.)Also, some buffaloes have more of a problem with milks letdown than  dairy cows (although not as much of a problem as some native cattle breeds in the  tropics). Frequently, a calf is kept with the cow and is tied to her foreleg at milking  time. In India, Burma, and other countries a dummy calf may be provided; playing  music seems to work, too.  </P>

559  </Description>
562<P ALIGN="JUSTIFY">The water buffalo is the classic work animal of Asia, an integral part of that  continent's traditional village farming structure. Probably the most adaptable and  versatile of all work animals, it is widely used to plow; level land; plant crops; puddle  rice fields; cultivate field crops; pump water; haul carts, sleds, and shallow-draft  boats; carry people; thresh grain; press sugar cane; haul logs; and much more.  Even today, water buffaloes provide 20-30 percent of the farm power in South  China, Thailand, Indonesia, Malaysia, Philippines, and Indochina(Figures provided by A. J. de veer. In India water buffaloes contribute much less to  farm power (6-12 percent); bullocks are more commonly used. In Pakistan  buffaloes are little used for farm power (1-2 percent) but provide much of the road  haulage. Papua New Guinea has no tradition of using any work animal, but villagers  are increasingly using buffaloes for farm work and the government is employing  Fillipinos to train them) . Millions of  peasants in the Far East, Middle East, and Near East have a draft buffalo. For them  it is often the only method of farming food crops.  </P>
564<P ALIGN="JUSTIFY">As fuel becomes scarce and expensive in these countries, the buffalo is being used  more frequently as a draft animal. ln 1979 water buffalo prices soared in rural  Thailand because of the increased demand.  </P>
566<P ALIGN="JUSTIFY">Although Asian farms have increasingly mechanized in the last 20 years, it has  often proved difficult to persuade the farmer to replace his buffalo with a tractor  since the buffalo produces free fertilizer and does not require diesel fuel. Now there  is renewed official interest in draft power. Sri Lanka has recently opened up large  new tracts of farmland in the Mahawali Valley, creating such a demand for work  animals that buffalo shortages have become a national development problem.  Indonesia's transmigration schemes are also handicapped by shortages of animal  power.  </P>
568<P ALIGN="JUSTIFY">For many small farmers the buffalo represents capital. It is often the major  investment they have. Buffalo energy increases their productivity and allows them to  diversify. Even small farms have work animals that, like the farmer himself, subsist  off the farm. Tractors usually require at least four hectares for economical operation,  which precludes their use on most peasant farms. Further, the infrastructure to  maintain machinery is often not readily available.  </P>
570<P ALIGN="JUSTIFY">Buffaloes are also used for hauling. Buffalo-drawn carts carry goods between  villages where road surfaces are unfit for trucks. The animals easily traverse  ravines, streams, paddies, and narrow and rocky trails. In the cities carts can  compete economically with trucks where the road surface is unprepared, where  loading or unloading takes longer than the journey itself, or where the loads are too  small and distances too short to make trucking economical. For road haulage  buffaloes are generally shod: the shoes are flat plates fitted to each hoof.  </P>
572<P ALIGN="JUSTIFY">&nbsp;</P>
573<P ALIGN="JUSTIFY">Capacity for Work</P>
575<P ALIGN="JUSTIFY">The water buffalo is a sturdy draft animal Its body structure, especially the  distribution of body weight over the feet and legs, is an important advantage. Its  large boxy hooves allow it to move in the soft mud of rice fields. Moreover, the  buffalo has very flexible pastern and fetlock joints in the lower leg so that it can bend  back its hooves and step over obstacles more easily than cattle. This water-loving  animal is particularly well adapted to paddy farming because its legs withstand  continual wet conditions better than mules or oxen(Australian animal scientists working in Bogor, Indonesia, found that the puddling  effect of buffalo hooves on the soil was critical for rice cultivation in the local soils.  Tractors produced fields so porous that they drained dry. (Information supplied by  A. F. GurnettSmith.) On one research station near Darwin, Australia, buffaloes were  used to prevent water draining from a dam. (Information supplied by D. G. Tulloch.). </P>
577<P ALIGN="JUSTIFY">Although buffaloes are preferred by farmers in the wet, often muddy lowlands of  Asia, mules, horses, and cattle move more rapidly and are preferred in the dryer  areas.  </P>
579<P ALIGN="JUSTIFY">Water buffaloes do not work quickly. They plod along at about 3 km per hour. In  most parts of Southeast Asia they are worked about 5 hours a day and they may  take 6-10 days to plow, harrow, and grade one hectare of rice field. Their stamina  and drawing power increase with body weight.  </P>
581<P ALIGN="JUSTIFY">Because they have difficulty keeping cool in hot, humid weather (see next chapter),  it is necessary to let working buffaloes cool off, preferably in a wallow, every 2 hours  or so. Without this their body temperatures may rise to dangerous levels.  </P>
583<P ALIGN="JUSTIFY">A pair of 3-year-old buffaloes costs about the same as a small tractor in Thailand.  But many farmers raise their own calves and there is no investment beyond labor.  The "fuel" for the animals comes mainly from village pastures and farm wastes such  as crop stubble and sugarcane tops. Buffaloes have an average working life of  about 11 years, but some work to age 20.  </P>
585<P ALIGN="JUSTIFY">  </P>
586<P ALIGN="JUSTIFY">Harness</P>
588<P ALIGN="JUSTIFY">The yoke used on working buffalo in Asia has changed very little in the last 1,500 years. It is doubtful that a working buffalo can exert its full power with it. The hard wooden yoke presses on a very small area on top of the animal's neck, producing severe calluses, galls, and obvious discomfort. The harness tends to choke the animal as the straps under the neck tighten into the windpipe. Since the traditional hitch is usually higher than the buffalo's low center of gravity, the animal cannot pull efficiently. Considerably more pulling power and endurance can be obtained by improving the harness. The situation is not unlike that in Western agriculture in the twelfth century when the horse collar-one of the most important inventions of the Middle Ages first appeared. Before that, horses were yoked like buffalo and the harness passed across their windpipes and choked them as they pulled. Use of the horse collar improved pulling efficiency and speeded the development of transportation and trade.  </P>
590<P ALIGN="JUSTIFY">The curved yoke now universally used on water buffalo contacts an area of the neck that is only about 200 cm2 (little more than half the size of this page). The entire load is pulled on this small area and causes the wood to dig into the flesh.  </P>
592<P ALIGN="JUSTIFY">A horse collar is a padded leather device that encircles the animal's neck. One modified in Thailand for use on water buffalo (see page 43) had a contact area of 650 cm2, more than three times that of the yoke it replaced. The collar's padding pressed against the animal's shoulders, not its neck, and  therefore did not choke it. Attached to the collar were wooden hames with the traces for hitching the animal to a wagon or plow. In trials a buffalo pulled loads 24 percent heavier with the collar than with the yoke, and the horsepower it developed increased by 48 percent(These trials were conducted by J. K. Garner in Thailand in 1958. In the maximum-load test the yoked buffalo failed to move a load of 570 kg, but it moved a load of 640 kg when fitted with the horse collar. In an endurance test the yoked animal took 35 minutes to pull a load 550 m, but harnessed with the collar it took only 21 minutes). </P>
594<P ALIGN="JUSTIFY">Another potentially valuable harness is the breast strap, a set of broad leather straps that pass over the animal's neck and back. One breast strap modified for water buffalo use had a contact area of 620 cm2, almost as much as that of the horse collar, and in trials the buffalo pulled a load 12 percent heavier than with a yoke and the horsepower it developed increased by almost 70 percent( The same animal used in the horse collar trials pulled 700 kg with the breast strap, in the endurance test it took 18.5 minutes to travel the 550-m distance). </P>
596<P ALIGN="JUSTIFY">These seem very good innovations. In the humid tropics, however, leather collars and breast straps may decay rapidly. To make them widely practical may require experimentation with, or development of, special leather treatments or more durable materials.  </P>

623  </Description>
626<P ALIGN="JUSTIFY">Heat Tolerance</P>
628<P ALIGN="JUSTIFY">While the buffalo is remarkably versatile, it has less physiological adaptation to extremes of heat and cold than the various breeds of cattle. Body temperatures of buffaloes are actually lower than those of cattle, but buffalo skin is usually black and heat absorbent and only sparsely protected by hair. Also, buffalo skin has one-sixth the density of sweat glands that cattle skin has, so buffaloes dissipate heat poorly by sweating. If worked or  driven excessively in the hot sun, a buffalo's body temperature, pulse rate, respiration rate, and general discomfort increase more quickly than those of cattle(Failure to appreciate this has caused many buffalo deaths in northern Australia when the animals were herded long distances through the heat of the day as if they were cattle).. This is particularly true of young calves and pregnant females. During one trial in Egypt 2 hours' exposure to sun caused temperatures of buffalo to rise 1.3°C, whereas temperatures of cattle rose only 0.2-0.3°C.  </P>
630<P ALIGN="JUSTIFY">Buffaloes prefer to cool off in a wallow rather than seek shade. They may wallow for up to 5 hours a day when temperatures and humidity are high. Immersed in water or mud, chewing with half-closed eyes, buffaloes are a picture of bliss.  </P>
632<P ALIGN="JUSTIFY">In shade or in a wallow buffaloes cool off quickly, perhaps because a black skin rich in blood vessels conducts and radiates heat efficiently (Tests at the University of Florida have shown that buffaloes in the shade cool off more quickly than cattle. -Robey, 1976).  Nonetheless, wallowing is not essential. Experience in Australia, Trinidad, Florida, Malaysia, and elsewhere has shown that buffaloes grow normally without wallowing as long as adequate shade is available.  </P>
634<P ALIGN="JUSTIFY">&nbsp;</P>
635<P ALIGN="JUSTIFY">Cold Tolerance</P>
637<P ALIGN="JUSTIFY">Although generally associated with the humid tropics, buffaloes, as already noted, have been reared for centuries in temperate countries such as Italy, Greece, Yugoslavia, Bulgaria, Hungary, Romania, and in the Azerbaijan and Georgian republics of the USSR. In 1807 Napoleon brought Italian buffaloes to the Landes region of southwest France and released them near Mont-deMarsan. They became feral and multiplied prodigiously in the woods and dunes of the littoral, but unfortunately the local peasants found them easy targets, and with the fall of Napoleon the whole herd was killed for meat(In the twelfth century Benedictine monks introduced buffaloes from their possessions in the Orient to work the lands of their abbey at Auge in northeastern France. In the thirteenth century a herd was introduced to England by the Earl of Cornwall, the brother of Henry III. Nothing is known about how well either herd survived). Buffaloes are also maintained on the high, snowy plateaus of Turkey as well as in Afghanistan and the northern mountains of Pakistan.  </P>
639<P ALIGN="JUSTIFY">The buffalo has greater tolerance of cold weather than is commonly supposed. The current range of the buffalo extends as far north as 45° latitude in Romania and the sizable herds in Italy and the Soviet Union range over 40° N latitude(Philadelphia and Peking are at comparable latitudes. In the Southern Hemisphere the 40° line of latitude easily encompasses Cape Town, Buenos Aires, Melbourne, and most of New Zealand's North Island).  Cold winds and rapid drops in temperatures, however, appear to have caused illness, pneumonia, and sometimes death. Most of the animals in Europe are of the Mediterranean breed, but other River-type buffaloes (mainly Murrahs from India) have been introduced to Bulgaria and the Soviet Union, which indicates that River breeds, at least, have some cold tolerance.  </P>
641<P ALIGN="JUSTIFY">&nbsp;</P>
642<P ALIGN="JUSTIFY">Altitude</P>
644<P ALIGN="JUSTIFY">Although water buffaloes are generally reared at low elevations, a herd of Swamp buffaloes is thriving at Kandep in Papua New Guinea, 2,500 m above sea level. And in Nepal, River buffaloes are routinely found at or above 2,800 m altitude.  </P>
646<P ALIGN="JUSTIFY">&nbsp;</P>
647<P ALIGN="JUSTIFY">Wetlands</P>
649<P ALIGN="JUSTIFY">Water buffaloes are well adapted to swamps and to areas subject to flooding. They are at home in the marshes of southern Iraq and of the Amazon, the tidal plains near Darwin, Australia, the Pontine Marshes in south-central Italy, the Orinoco Basin of Venezuela, and other areas.  </P>
651<P ALIGN="JUSTIFY">In the Amazon, buffaloes (Mediterranean and Swamp breeds) are demonstrating their exceptional adaptability to flood areas. Buffalo productivity outstrips that of cattle, with males reaching 400 kg in 30 months on a diet of native grasses( Information supplied by C. Nascimento). </P>
653<P ALIGN="JUSTIFY">The advantage of water buffaloes over Holstein, Brown Swiss, and Criollo cattle was demonstrated in a test at Delta Amacuro, Venezuela, when the cattle developed serious foot rot In the wet conditions of the Orinoco Delta and had to be withdrawn from the test. The area of Venezuela is flooded 6 months of the year and creates constant problems for cattle, yet the buffalo seems to adapt well(*Information supplied by A. Ferrer). </P>
655<P ALIGN="JUSTIFY">High humidities seem to affect buffaloes less than cattle. In fact, if shade or wallows are available, buffaloes may be superior to cattle in humid areas.</P>
657<P ALIGN="JUSTIFY">In southern Brazil, trials comparing buffalo and cattle on subtropical riverine plains have favored the buffalo also. This work is being carried out on native pastures, mostly in  the State of Sao Paulo.  </P>

689<P ALIGN="JUSTIFY">Most buffaloes are located in countries where land, cultivated forage crops, and pastures  are limited. Livestock must feed on poor-quality forages, sometimes supplemented with  a little green fodder or byproducts from food, grain, and oil seed processing. Usually  feedstuffs are in such short supply that few animals have a balanced diet, but the buffalo  seems to perform fairly well under such adverse conditions.  </P>
691<P ALIGN="JUSTIFY">&nbsp;</P>
692<P ALIGN="JUSTIFY">Growth Rate</P>
694<P ALIGN="JUSTIFY">Insufficient measurements have been taken to allow unequivocal state. meets about the  relative growth rates of cattle and buffaloes. However, many observations made in  various parts of the world indicate that the buffalo's growth is seldom inferior to that of  cattle breeds found in the same environments. Some observations are given below.  </P>
696<P ALIGN="JUSTIFY">· Trials in Trinidad in the early 1960s involved buffaloes grazing pangola grass (Digitaria  decumbens) together with Brahman and Jamaican Red cattle. Over a period of 20  months the buffaloes gained an average of 0.72 kg per day, whereas the cattle on a  comparable nearby pasture gained 0.63 per day(Experiments performed by P. N. Wilson. -Information supplied by S. P. Bennett.).  </P>
698<P ALIGN="JUSTIFY">· In the Orinoco Delta of Venezuela unselected Criollo/Zebu crossbred cattle gained  0-0.2 kg per day on Paspalum fasciculatum, whereas the water buffaloes with them  gained 0.25-0.4 kg per day(Cunha  et al., 1975).  </P>
700<P ALIGN="JUSTIFY">· In the Apure Valley of Venezuela, 100 buffalo steers studied in 1979 reached an  average weight of 508 kg in 30 months, whereas the 30-month old Zebu steers tested  with them weighed 320 kg. The feed consumed was a blend of native grasses (25  percent of the diet) and improved grasses (such as pangola, pare, and guinea grass)( Information supplied by A. Ferrer). In  the same valley 200 buffalo heifers (air freighted from Australia) produced weight gains  averaging 0.5 kg per day over a 2-year period (and 72 percent of them calved). Government statistics for the area record average weight gains in crossbreeds between Zebu and Criollo cattle as 0.28 kg per day (with 40 percent calving).  </P>
702<P ALIGN="JUSTIFY">· In the Philippines, buffaloes showed weight gains of 0.75-1.25 kg per day, the same as those of cattle. </P>
704<P ALIGN="JUSTIFY">· Daily weight gains of over 1 kg have been recorded for buffaloes in Bulgaria and Yugoslavia.  </P>
706<P ALIGN="JUSTIFY">· Liveweight gains of 0.80 kg per day have been recorded for buffaloes in Papua New Guinea. In a very humid, swampy area of the Sepik River coastal plains liveweight gains by males averaged 0.47 kg per day and females 0.43 kg per day for more than a year. The average weight of 30 4-year-old female buffaloes was 375 kg, while the average weight of 4-year-old female Brahman/ Shorthorn crossbred cattle was 320 kg.  </P>
708<P ALIGN="JUSTIFY">· At the research station near Belem in the Brazilian Amazon weaned Murrah buffaloes, pastured continuously on Echinochloa pyramidalis (a nutritious grass), gained 0.8 kg daily and reached 450 kg in about 18 months. </P>
710<P ALIGN="JUSTIFY">· Liveweight gains of 0.74-l.i kg per day have been obtained in Australia. Buffalo steers grew as fast or faster than crossbred Brahman cattle on several improved pastures near Darwin, but on one very poor pasture, 40-year-old buffaloes each weighed only 400 kg, whereas the Brahman crossbred steers reared with them weighed 500 kg. The reason for this is not clear.  </P>

713<P ALIGN="JUSTIFY">Efficiency of Digestion</P>
715<P ALIGN="JUSTIFY">Indian animal nutritionists have investigated water buffaloes intensively over the past two decades. Many have reported that buffaloes digest feeds more efficiently than do cattle, particularly when feeds are of poor quality and are high in cellulose.One trial revealed that the digestibility of wheat straw cellulose was 24.3 percent for cattle and 30.7 percent for buffalo. The figures for berseem (Trifolium alexandrinum) cellulose were 34.6 percent for cattle and 52.2 percent for buffalo. In another trial the digestion of straw fiber was 64.7 percent in cattle, 79.8 percent in buffalo.</P>
717<P ALIGN="JUSTIFY">Other nutrients reported to be more highly digested in buffaloes than in cattle (Zebu) are crude fat, calcium and phosphorus, and nonprotein nitrogen.  </P>
719<P ALIGN="JUSTIFY">Recent experiments in India suggest that buffaloes also are able to utilize nitrogen more efficiently than cattle. Buffaloes digested less crude protein than cattle in one trial but increased their body nitrogen more (and they were being fed only 40 percent of the recommended daily intake of crude protein).  </P>
721<P ALIGN="JUSTIFY">The ability of buffaloes to digest fiber efficiently may be partly due to the microorganisms in their rumen. Several Indian research teams have published data indicating that the microbes in the buffalo rumen convert feed into energy more efficiently than do those in cattle (as measured by the rate of production of volatile fatty acids in the rumen).  </P>
723<P ALIGN="JUSTIFY">Also, in laboratory studies samples of buffalo rumen contents produced volatile fatty acids more quickly from a variety of animal feedstuffs than did samples from the rumen of cattle  </P>
725<P ALIGN="JUSTIFY">No single reason alone explains the buffalo's success in using poor quality forages. Rather, it is a combination of reasons that differ with the breed and conditions used. Studies by other researchers suggest that additional causes might include:  </P>
727<P ALIGN="JUSTIFY">· Higher dry matter intake; </P>
728<P ALIGN="JUSTIFY">· Longer retention of feed in digestive tract;  </P>
729<P ALIGN="JUSTIFY">· Ruminal characteristics more favorable to ammonia-nitrogen utilization;  </P>
730<P ALIGN="JUSTIFY">· Less depression of cellulose digestion by soluble carbohydrates (e.g., starch or molasses);  </P>
731<P ALIGN="JUSTIFY">· Superior ability to handle stressful environment; and  </P>
732<P ALIGN="JUSTIFY">· A wider range of grazing preferences.  </P>

735<P ALIGN="JUSTIFY">Calf Growth Rates</P>
737<P ALIGN="JUSTIFY">Although the buffalo's gestation period is more than a month longer than that of cattle, the calves are born weighing 35-40 kg, or about the same as that of a newborn Holstein calf. But because buffalo milk has about twice the butterfat of cow's milk, the calves grow very quickly. They also suffer more shock at weaning and have to be slowly changed to their new feeding program. Buffaloes can be marketed as full-grown animals for beef at the age of 2-3 years, sometimes even earlier.  </P>

740 Table 5 Some Coarse Grasses and Forages Palatable to Buffaloes but Less Readily</P>
742<P ALIGN="JUSTIFY">For example, in Indonesia it has been found that buffalo steers can be marketed 6 months before Zebu steers because they may be 100 kg heavier. In Egypt some buffalo calves given feed supplemented with concentrates weighed 360 kg at 1 year of age. At Ain Shams University near Cairo, buffalo calves weaned at 7-14 days of age gained 0.7 kg per day from weaning to slaughter at 18 months of age and weighed 400 kg. Rice straw comprised 50 percent of the finishing diet.  </P>
744<P ALIGN="JUSTIFY">Buffaloes on Italian farms have reached 350 kg in 15-18 months and some year-old calves weighed 320 kg. </P>
746<P ALIGN="JUSTIFY">Grazing trials on native pasture (with mineral supplementation) in the Brazilian Amazon indicate that buffalo calves grew faster than cattle. At 2 years of age Mediterranean-type buffaloes averaged 369 kg, Swamp type, 322 kg, and Jafarabadi type, 308 kg. The Zebu cattle tested with them averaged 265 kg and the crossbred Zebu/Charolais, 282 kg. </P>
748<P ALIGN="JUSTIFY">&nbsp;</P>
749<P ALIGN="JUSTIFY">Feed Preferences</P>
751<P ALIGN="JUSTIFY">Buffaloes graze a wider range of plants than cattle. During floods near Manaus in the  Brazilian Amazon when cattle become marooned on small patches of high ground,  many suffer from foot rot and many starve to death. Their buffalo companions on the  other hand-bodies sleek and full-swim out to islands of floating aquatic plants and eat  them, treading water. Also, they dive almost 2 m to graze beneath the floodwaters. </P>
753<P ALIGN="JUSTIFY">University of Florida buffaloes in a lakefront voluntarily consumed vines, sedges, rushes, floating aquatic weeds, and the leaves and shoots of willows and other  trees along the water's edge. Few of these plants are voluntarily grazed by cattle. In  northern Australia water buffaloes graze the very pickily leaves of pandanus; they also  graze sedges, reeds, floating grass, and aquatic weeds. Hungry buffaloes will eat bark,  twigs, and other unpalatable vegetation.  </P>
755<P ALIGN="JUSTIFY">Because of the variety of their tastes they have been used in northern Queensland,  Australia, to clear pastures of woody weeds left untouched by cattle. In some countries  cattle are used to graze the palatable tops of pasture plants and are followed by  buffaloes to graze the less desirable lower parts.  </P>

857    <Metadata name="Title">7 Health</Metadata>
858  </Description>
861<P ALIGN="JUSTIFY">When compared with other domestic livestock, the water buffalo generally is a healthy animal. This is particularly impressive because most of them live in hot, humid regions that are conducive to disease, and the buffalo is a bovine susceptible to most diseases and parasites that afflict cattle. Although the reasons are not specifically known, the effect of disease on the buffalo and its productivity is often less deleterious than on cattle.  </P>
863<P ALIGN="JUSTIFY">Antibiotics and vaccines developed for cattle work equally well on buffaloes. As a result, treatments are available for most of the serious diseases of buffaloes, although some are not very effective for either animal.  </P>
865<P ALIGN="JUSTIFY">The greatest buffalo losses are often among calves. Newborn buffalo calves, like bovine calves, can succumb in large numbers to viruses, bacteria, and poor nutrition. This is largely due to poor management during the calf's frst 2 months of life. For example, as noted previously, villagers in some countries often sell the valuable buffalo milk, thus depriving the calves.  </P>
867<P ALIGN="JUSTIFY">Buffalo calf losses are often similar to those of the cattle around them, but the animal's proclivity for wallowing exposes calves to waterborne diseases. Further, a young one occasionally drowns when an adult rolls on top of it.  </P>
869<P ALIGN="JUSTIFY">Reactions to some specific diseases and parasites are discussed below.  </P>
871<P ALIGN="JUSTIFY">Pasteurellosis- Probably the water buffalo's most serious disease, pasteurellosis, or hemorrhagic septicemia, is caused by the bacterium Pasteurella multocida (P. septica). Buffaloes are more susceptible to it than cattle and die in large numbers where pasteurellosis occurs. A vaccine against pasteurellosis is effective in protecting both buffaloes and cattle; it is cheap and easily made.  </P>
873<P ALIGN="JUSTIFY">Tuberculosis- Despite some claims to the contrary, the water buffalo is susceptible to the bovine strain of tuberculosis (Alycobacterium bovis). Scattered reports from different parts of India indicate no difference in the incidence of infection between cattle and buffaloes(Information supplied by S. K. Misra, Department of Veterinary Medicine, Punjab Agricultural University, Ludhiana, Punjab, India).  Other strains of mycobacteria have been isolated from feral buffaloes and cattle in northern Australia but seem to have little effect on the animals. Tuberculosis occurs among the buffalo herds of the world only because most are kept under unsanitary conditions(In 1905 buffaloes were introduced to Trinidad because the cattle herds (Zebu and srahman breeds) were infected with tuberculosis and, in those days, it was thought that buffaloes were resistant to the disease. Most were housed in muddy, ill-kept pens and forced to eat sugarcane tops off the ground; consequently, in 1949 over 30 percent of the buffaloes reacted to the tuberculin test. (The cattle herds had 80 percent reactors.) Tuberculosis was eliminated in Trinidad's buffaloes by improving the sanitary conditions: installing concrete floors and mangers and cleaning the pens regularly. This, together with regular tuberculin testing and removal of reactors, led to such a dramatic improvement that buffalo tuberculosis is now virtually unknown. -Information supplied by S. K. Bennett.) </P>
875<P ALIGN="JUSTIFY">Brucellosis-Buffaloes and cattle are equally susceptible to brucellosis. Although seldom reported as a problem elsewhere, brucellosis in Venezuela is increasing more rapidly among buffaloes than among cattle. In India the disease is no more prevalent among buffaloes than among cattle.  As many as 57 percent of some Venezuelan herds are infected with the disease. It is a frequent cause of abortion in buffaloes. Serologic procedures and measures developed for the control of the disease in cattle are also effective means of curbing this infection in buffaloes. (Consumption of raw milk or contact with aborted fetuses may cause undulant fever in humans.)  </P>
877<P ALIGN="JUSTIFY">Mastitis- Among milking buffaloes mastitis is a problem as it is in dairy cows, but to a lesser extent. It is likely to increase, however, as the milk production per individual buffalo is increased. The bacteria that cause mastitis in the buffalo are similar to those in cattle. Treatment and control programs used for cattle are equally effective for buffaloes.  </P>
879<P ALIGN="JUSTIFY">Other Diseases -Among the epizootic diseases, rinderpest and piroplasmosis seem to affect buffaloes as much as cattle. Foot-and-mouth disease also affects buffaloes, but to a lesser degree than cattle, producing smaller lesions and having a lower incidence. In northern Australia buffaloes deliberately infected with bovine pleuropneumonia bacteria exhibited slight fever, but the disease never appeared. No naturally occurring eases have been reported in buffaloes. </P>
881<P ALIGN="JUSTIFY">Ticks -Buffaloes are notably resistant, although not immune, to ticks. In a tick-infested area of northern Australia only 2 engorged female ticks were found on 13 adult buffaloes during a 2-year test. Accordingly, healthy buffaloes are not commonly affected by diseases borne by ticks nor are the hides damaged by their bites. Since ticks are rarely found on buffaloes, anaplasmosis, theileriasis, and babesiosis, which are tick-borne, have little effect on buffaloes in the field. (Buffaloes and cattle are equally susceptible, however, if inoculated with East Coast fever, a form of theileriasis.) This is important because tick infestations in cattle are particularly troublesome in the tropics and the pesticides used to control them are becoming ineffective as the ticks develop resistance. The pesticides are also becoming expensive.  </P>
883<P ALIGN="JUSTIFY">The basis of the buffalo's tick resistance is not known, but wallowing and rubbing may play a role in it; animals kept in experimental concrete pens in Australia have developed heavy tick infestation. (rials carried out on Magnetic Island by R. H. V/harton, Commonwealth Scientiflc and Industrial Research Organisation, Townsville, Queensland, Australia). </P>

886 Table 6 Some Infections and Parasites of Buffalo</P>
888<P ALIGN="JUSTIFY">Screwworm- Larvae of the screwworm fly (Callitroge species), a major pest of livestock in Central and South America and some other tropical areas, do not affect adult water buffalo. In Venezuelan areas where cattle (Zebu type) are severely infested, adult water buffaloes are virtually free of screwworm larvae and the umbilicus of newborn calves seldom if ever becomes infected. ( Information supplied by A. Ferrer). </P>
890<P ALIGN="JUSTIFY">The same is true in Papua New Guinea. It is thought that the mud plaster produced by wallowing suffocates the larvae, but in India screwworms do not affect water buffaloes either, and there they wallow in fairly clear water and the farmer usually washes them off. </P>
892<P ALIGN="JUSTIFY">Roundworm- The heavy losses of young buffalo calves throughout the world are caused, in large measure, by the roundworm Toxocara vitulorum. The calves seem more susceptible than mature animals and they become infected before birth or within 24 hours after birth through the mother's colostrum. The roundworm is the most serious buffalo parasite and in untreated calves the small intestine can get packed with worms to the point of complete occlusion. Although huge numbers of calves die each year, anthelmintic drugs that control roundworms are highly effective and widely available.  </P>
894<P ALIGN="JUSTIFY">The adult water buffalo appears to have a high degree of resistance to strongyloid nematodes. Being such excellent converters of rough fodders they do not suffer the nutritional deficiency and the resulting liability to these roundworms experienced seasonally by cattle.  </P>
896<P ALIGN="JUSTIFY">Liver Fluke- During wallowing, water buffaloes can easily become infected with the waterborne infective stages of liver fluke (Fasciola gigantica). Although the number of flukes in a buffalo may be phenomenally high, no clinical signs of the disease are usually evident. It seems likely that the resulting liver damage reduces the growth and the work and milk production of buffaloes more than is generally appreciated.  </P>
898<P ALIGN="JUSTIFY">Trypanosomiasis- The water buffalo is susceptible to trypanosomiasis and is reportedly more susceptible than cattle to Trypanosoma evansi.Experience with the animal in Africa is limited, but trypanosomiasis may be the reason why Egypt is the only African country that has traditionally employed water buffalo.  </P>
900<P ALIGN="JUSTIFY">Other Parasites- The wallow and its resulting mud cake seem to protect water buffalo from many biting flies, but the main ectoparasite in Australia and Southeast Asia is the buffalo fly (Siphona spp.). Pediculosis, caused by the sucking louse (Hematopinus tuberculatus), occurs widely among buffalo, and sarcoptic mange (Sarcoptes scabiei var. bubalus) is a serious disease, especially among calves and during dry seasons when wallowing opportunities are restricted. The lung worm Dictyocaulus ririparus thrives in warm, humid areas and sometimes infects buffaloes heavily, although its outward manifestations are rare.  </P>

958    <Metadata name="Title">8 Reproduction</Metadata>
959  </Description>
962<P ALIGN="JUSTIFY">The water buffalo has a reputation for being a sluggish breeder, but the average animal is so poorly fed that its reproductive performance is unrepresentative of its capabilities. Without reasonable nutrition the animals cannot reach puberty as early in life or reproduce as regularly as their physiology or genetic capability would normally allow.  </P>
964<P ALIGN="JUSTIFY">Actually, adequately nourished buffaloes reach puberty at about the same age as cattle, as early as 18 months of age in buffalo bulls. In northern Australia Swamp females have conceived even as early as 14 months of age and feral buffaloes routinely conceive at 16 months of age. In the herd at Punjab Agricultural University in Ludhiana, India, 11 River buffalo heifers showed estrus at ages less than 18.5 months and a few came into heat when less than 15 months old. </P>
966<P ALIGN="JUSTIFY">The water buffalo also can calve at an age comparable to that of cattle. At the Ain Shams University in Egypt a well-fed Egyptian buffalo herd of several hundred animals has an average age at first calving of 27 months, 22 days(Information supplied by M. El Ashry. Because of nutritional uncertainties, El Ashry and his colleagues believe that body weight is a better indicator of sexual preparedness than age is. These researchers at Ain Shams University recommend mating heifers when they weigh 365 kg no matter what their age. Research at Punjab Agricultural University shows that buffalo heifers can be bred when they weigh over 270 kg and manifest estrus).Most animals in the Punjab Agricultural University River buffalo herd calved before 35 months, one at 28.3 months.! In one Venezuelan herd almost all heifers 20-24 months old were pregnant; virtually all calved before age 38 months, most by 30 months, and one at age 23 months. </P>
968<P ALIGN="JUSTIFY">In trials in Queensland, Australia, and in Papua New Guinea buffaloes produced more calves over a 3-year period than the cattle tested with them. In the hot, humid Sepik Plains in northern Papua New Guinea it was noticed that female buffaloes (Swamp breed) came into estrus even while they were losing weight because of inadequate nutrition, whereas cattle did not. Under these stressful conditions the buffalo calves also reached sexual maturity earlier and the buffaloes had a higher calving percentage and a shorter calving interval because they came back into estrus more quickly than cattle(Information supplied by J. Schottler. The age at first calving of more than 60 nutritionally poor buffaloes was 38 months in one herd and 45 months for Brahman cross cattle) . Similar observations have been made in Florida, Trinidad, the Brazilian Amazon, Venezuela, and elsewhere. Although these are exceptions to the normal observations in Asia, where buffaloes seem to breed more slowly than cattle, they do demonstrate the buffalo's potential for improved breeding.  </P>
970<P ALIGN="JUSTIFY">Estrus in buffalo cows usually lasts about 24 hours, but duration varies and may range from 11 to 72 hours. It occurs on an average 21-day cycle. Determination of when a cow is in estrus is difficult because often the animal shows few outward signs of "heat." This increases the chances of missing a cycle, especially for artificial insemination. Unclean surroundings, poor nutrition, and poor management, cause a high death rate among calves; this also contributes to the buffalo's often low reproductive rate.  </P>
972<P ALIGN="JUSTIFY">In many areas, calving is seasonal. This seems to be largely due to changes in nutrition. It may also be caused by heat stress, in either males or females, which results in a low breeding rate during the hot season. However, when buffalo cows are well fed, they come into estrus and will breed in any season.  </P>
974<P ALIGN="JUSTIFY">Many matings take place at night and are therefore unobserved. In one set of pregnancy diagnoses in northern Australia, the buffalo's conception rate (81 percent) was higher than that of the Brahman crossbreeds (70 percent) they were with. In India, artificial insemination of water buffaloes began in the late 1950s. Deep-frozen semen is now available and its use is spreading. Overall conception rates of 70-80 percent are obtained. It is estimated that some 100,000 buffaloes are now being artificially inseminated.</P>
976<P ALIGN="JUSTIFY">The water buffalo's gestation period is about one month longer and is more variable than that of cattle. Whereas cattle give birth after about 280 days (Angus, 279, Holstein, 279-280, Brown Swiss, 286), buffaloes take 300334 days (average 310) or roughly 10 months and 10 days (differences between breeds are unknown). In Punjab, India, River buffaloes have been observed to come into estrus as early as 40 days after calving. </P>
978<P ALIGN="JUSTIFY">Nonetheless, only under uncommon circumstances can a buffalo cow produce a calf each year. In one herd of 800 cows in Venezuela the average female buffalo over age 4 produces 2 calves every 3 years. In response to a recent questionnaire, the majority of Indonesian farmers estimated that the calving rate was between 3 and 4 calves in 5 years. A few claimed a calf a year, some only 1 or 2 calves In 5 years. In Florida it has been noted that some buffalo cows having just calved became pregnant more quickly than cattle, so that a calf may indeed be produced each year. Regular yearly breeding has been noted also in northern Australia.</P>
980<P ALIGN="JUSTIFY">The incidence of abortion, dystocia, retained placenta, and other parturition problems in buffaloes is similar to that in cattle. Twinning is very rare; probably no more than 0.01 percent of buffalo pregnancies produce twins.</P>
982<P ALIGN="JUSTIFY">Preliminary results in northern Australia indicate that weaning can be carried out as late as 12 months of age without any effect on conception time of the buffalo dam.  </P>

1036    <Metadata name="Title">9 Management</Metadata>
1037  </Description>
1040<P ALIGN="JUSTIFY">Water buffaloes are adaptable and are managed in many ways. In general, they are raised like cattle. But in some operations they must be handled differently. This chapter highlights these differences.  </P>
1042<P ALIGN="JUSTIFY">Millions of water buffaloes are managed in "backyards" in Asia. They exist on the resources of small holdings. Management and expenditures are minimal. Care of the family buffalo is usually entrusted to children, old people, or women not engaged in other farm duties; the buffalo allows them to be useful and productive.  </P>
1044<P ALIGN="JUSTIFY">The buffalo fits the resources available on the farm, but it is also an urban animal. Thousands of herds of 2-20 buffaloes may be found in the cities and towns of India, Pakistan, and Egypt-all fed, managed, and milked in the streets.  </P>
1046<P ALIGN="JUSTIFY">In addition, the buffalo has important qualities as a feedlot animal; it can be herded and handled with relative ease because of its placid nature. The Anand Cooperative in India's Gujarat State, which daily contributes thousands of gallons of milk to Operation Flood (the world's largest nutrition project), involves more than 150,000 Surti buffaloes that are fed, managed, and milked by their owners under feedlot-like conditions in their villages. Many of Italy's 100,000 buffaloes are maintained under similar conditions.  </P>
1048<P ALIGN="JUSTIFY">Water buffaloes can also be managed on rangelands. In Brazil, Venezuela, Trinidad, the United States, Australia, Papua New Guinea, Malaysia, Indonesia, the Philippines, and elsewhere there is rising interest in raising buffalo beef on the range. The production practices for raising them are similar to those used for range cattle.  </P>
1050<P ALIGN="JUSTIFY">Water buffaloes in the humid tropics must be able to cool off. Shade trees are desirable, and although a wallow is not essential, it is probably the most effective way the animal has of coping with heat. Alternatively, water showers may be provided to wet down the animals 3-5 times during the hottest part of the day.  </P>
1052<P ALIGN="JUSTIFY">Water buffaloes are intelligent animals. Young ones learn patterns quickly and often are reluctant to change their habits. Feral animals-even those born in the wild-tame down after a week or two in a fenced enclosure to the point where many can be handled, haltered, and hand fed(In one example, loo feral buffalo were captured in Northern Territory, Australia. With in 14 days all the animals-males and females, young and old-had become docile and amenable to handling. -Information supplied by D. G. Tulloch) . Among feral herds of northern Australia it has been observed that buffaloes have clans and families. A female calf seems to remain with its family and mother for many years (possibly for life). A male calf stays until it is about 2 years old, when it is driven from the group by an adult bull. </P>
1054<P ALIGN="JUSTIFY">It has also been noted in northern Australia that free-ranging buffaloes instinctively select clean water areas to drink from, other areas to wallow in, and still others as "toilet areas." In addition, China's buffaloes reportedly are being "toilet trained" to defecate only at specific sites to avoid contaminating waterways with schistosome eggs.  </P>
1056<P ALIGN="JUSTIFY">Another interesting observation from northern Australia is that most buffalo dams readily adopt a calf that has been orphaned by the death of its mother. In fact, females will allow several calves to nurse (including calves of other mothers and sometimes even adults).  </P>
1058<P ALIGN="JUSTIFY">Buffaloes are also self-reliant. For several months each year in Vietnam and Malaysia, for instance, they are turned loose in the forests to fend for themselves.  </P>
1060<P ALIGN="JUSTIFY">Provision of adequate fencing is one of the great problems of buffalo management. The  animals have strong survival instincts and if feed runs short, such as in the dry season,  they will break through fences that would deter cattle who would remain and starve. They  will also break through fences if their family unit is split up. Barriers must be stronger  than those used for cattle and the wires closer together and lower to the ground because  buffaloes lift fences up with their horns rather than trample them down. In northern  Australia, Papua New Guinea, and Costa Rica it has been found that buffaloes are  particularly sensitive to electric fences (a single wire is all that is needed), and in Brazil a  special suspension fence has been devised(Moura Carvalho et al., 1979). Both of these  seem to be cheap and efficient answers to the fencing problem.  </P>
1062<P ALIGN="JUSTIFY">Water buffaloes are easily handled from horseback and easily worked through a corral.  Actually, because of their docility they can be mustered on foot, even on ranges where  cattle require horses. Unless they come from different areas they tend to herd together  and can be mustered like sheep.  </P>
1064<P ALIGN="JUSTIFY">One of the major management adjustments to be made by cattlemen is understanding  and capitalizing on the buffalo's placid nature. Buffaloes are naturally timid and startle  easily; they must be handled quietly and calmly. Rough handling, wild riding, and loud  shouting make handling them more difficult and training them much harder.</P>
1066<P ALIGN="JUSTIFY">Village buffaloes are led and managed by a ring threaded through the septum between  the nostrils. The technique is frequently applied crudely and cruelly, often resulting in a  ripped septum.  </P>
1068<P ALIGN="JUSTIFY">The identification of individual buffaloes is difficult. Fire brands do not remain legible on  the skin for long. Cryobranding (freeze branding) is more durable. Most types of ear tags  are not very successful; the numbers wear off and mud covers up the tag's color. In  northern Australia ear tattooing has been the most successful identification technique,  with tattoos remaining legible for at least 8 years(Between 1958 and 1962 hundreds of  Australian buffalo were shipped on the hoof to the meat markets in Hong Kong without  trouble, despite crowded shipboard conditions and the long sea voyage. But in 1962 one  roughly treated bull went berserk in Hong Kong and killed a handler, and the Hong Kong  authorities stopped the trade as a result, although the problem was really one of  mismanagement. Buffalo have since been sent by air from Australia to Venezuela,  Nigeria, and Papua New Guinea and by barge to Papua New Guinea. No handling  problems have been experienced en route).  When they pasture together, cattle and  buffaloes coexist satisfactorily. They segregate themselves into their own groups and do  not interfere with one another. The buffaloes, however, usually dominate the cattle and  tend to monopolize the areas with the best feed supply.  </P>
1070<P ALIGN="JUSTIFY">Feed troughs and mineral boxes used for cattle are suitable for buffaloes, but chutes and  crushes must be widened to accommodate the buffalo's broader body and, when  necessary, the Swamp buffalo's greater horn spread. </P>
1072<P ALIGN="JUSTIFY">Water buffaloes are powerful  swimmers. In Brazil they have been known to escape by swimming down the Amazon River. An unusual management difficulty is caused by piranha in the rivers and swamps of Venezuela. In one herd of 100 heifer buffaloes, 40 have lost all or part of a teat to these voracious fish.</P>
1074<P ALIGN="JUSTIFY">The horns of water buffaloes are seldom removed or prevented from growing, a  testament to the animal's docility. (When questioned, one Thai villager said that he wouldn't  allow it because it would be a disgrace to the buffalo.) However, the animals can be  dehorned as calves in the same manner as cattle. They are then easier to handle In  chutes and cause less accidental injury to neighboring animals, handlers, walls, and  trees.  </P>

1102    <Metadata name="Title">10 Environmental Effects</Metadata>
1103  </Description>
1106<P ALIGN="JUSTIFY">The grazing and wallowing habits of water buffaloes may have unexpected consequences when the animals are introduced to new, perhaps fragile environments. The presence of several thousand feral buffaloes on the coastal plains of northern Australia, for example, has become a very emotional issue among Australian environmentalists, some of whom foretell the complete destruction of the environment if the uncontrolled feral herds are not destroyed( It is not at all clear, however, that the buffaloes (which have existed in the area for 150 years) are causing the observed environmental degradation. Other possibilities include: fire, climatic stress, overgrazing, and a variety of farming, hunting, and other human activities, especially the use of four-wheel-drive vehicles. Thousands of wild pigs also share the area, along with crayfish that burrow into and weaken the levees that keep out the sea, something for which the buffaloes have been blamed). </P>
1108<P ALIGN="JUSTIFY">&nbsp;</P>
1109<P ALIGN="JUSTIFY">Soil Compaction</P>
1111<P ALIGN="JUSTIFY">Water buffaloes have larger hooves than cattle of comparable size and thus they compact the soil less. But buffaloes often live in damp, boggy areas where their feet may compact soft soils. Also, buffaloes are creatures of habit and, when able, they set up fixed points for drinking, feeding, defecating, wallowing, and sleeping. Between the points they wear sharply defined trails in the vegetation and soil.  </P>
1113<P ALIGN="JUSTIFY">&nbsp;</P>
1114<P ALIGN="JUSTIFY">Wallowing</P>
1116<P ALIGN="JUSTIFY">Possibly the water buffalo's greatest environmental limitation is its propensity to build wallows. In hot climates every buffalo will wallow at some time during the heat of the day if water is available. When they can, buffaloes will make their own wallows, enlarging a mud puddle by rolling in it or even using their heads to flip water out of a drinking trough and muddying the ground nearby.  </P>
1118<P ALIGN="JUSTIFY">The pasture in the immediate area of the wallow is usually damaged by trampling and waterholes may become fouled, but buffaloes return to the same wallow day after day and do not build new ones indiscriminately. Thus, the muddied area is not a large proportion of the location in which they graze unless a large number of animals are confined in a small space(At Gainesville, Florida (possibly because of its subtropical but not hot climate), a herd of 52 buffaloes concentrated in a one-hectare field did not attempt to build a wallow at ale -Information supplied by H. Popenoe.) . In addition, man-made wallows can be dug at safe sites and the animals will use them. The problem of wallowing is therefore not generally a serious one.  </P>
1120<P ALIGN="JUSTIFY">&nbsp;</P>
1121<P ALIGN="JUSTIFY">Damage to Waterways</P>
1123<P ALIGN="JUSTIFY">Because buffaloes often live near and enter water freely, they may cause erosion in ditches, river banks, canals, and levees. Also, their wallowing muddies the water, which may adversely affect some fish species and reduce the growth of algae. Buffaloes commonly urinate and defecate in the water, possibly creating a pollution hazard, although in most situations this contamination is likely to be minor.  </P>
1125<P ALIGN="JUSTIFY">The presence of this herbivore in natural waterways may reduce the number of water plants. Some plants are trampled, some eaten, and some underwater species are suppressed because the muddied water transmits less light. This (and several other of the buffalo's environmental effects) can be turned to advantage (see picture page 85) when, as often occurs, aquatic plants grow out of control and become obnoxious weeds.  </P>
1127<P ALIGN="JUSTIFY">&nbsp;</P>
1128<P ALIGN="JUSTIFY">Damage to Pastures</P>
1130<P ALIGN="JUSTIFY">Water buffaloes have very strong jaws, and when forage is sparse they graze it close to the ground; this overgrazing can destroy a pasture. In addition, they eat virtually all available plant material (including many species that cattle shun), so that a densely stocked pasture can become completely defoliated. In northern Australia it has been found that, with time, buffaloes become accustomed to a given pasture, and unless fences are strong they will instinctively return to it until the forage has been depleted.  </P>
1132<P ALIGN="JUSTIFY">The buffalo's inclination to eat many plants can be used to improve the environment and suppress growth of coarse weedy species of plants. On the Sepik Plains in Papua New Guinea buffaloes are being used to graze and suppress sedges (Cyperus species), as a result, the more desirable Paspalum species are beginning to appear. At Mount Bundy in northern Australia native pastures are being improved on a commercial scale by overstocking them with buffaloes. The animals reduce or completely eliminate spear grass and other weeds-even those with thorns-and thus foster the survival and growth of introduced forage legumes such as stylo (Stylosanthes guianensis). In Sri Lanka buffaloes have been used to graze out the vigorous tropical grass Imperata cylindrica.  </P>
1134<P ALIGN="JUSTIFY">&nbsp;</P>
1135<P ALIGN="JUSTIFY">Damage to Trees</P>
1137<P ALIGN="JUSTIFY">Buffaloes instinctively rub against trees (and walls and fences), eagerly browse leaves, and sometimes nibble bark, so they damage trees more so than cattle. In northern Australia it has been noted that each "family herd" of feral buffaloes selects one or two trees for rubbing against so that the rubbing damage is confined to them. </P>

1157    <Metadata name="Title">11 Recommendations and Research Needs</Metadata>
1158  </Description>
1161<P ALIGN="JUSTIFY">This report has outlined the water buffalo's apparent merits, but most of the statements made about the animal are based on empirical observations. Many of its most exciting and potentially valuable features have not been subjected to the careful scrutiny needed to confirm their validity.  </P>
1163<P ALIGN="JUSTIFY">Despite the fact that there are 130 million or more water buffalo in the world, research on the animal is scanty and limited to only a few situations and sites. Quantitative information (especially for the various breeds), tests, trials, and comparison studies are needed.  </P>
1165<P ALIGN="JUSTIFY">The research to be done on the water buffalo offers scientific challenges that can be undertaken in laboratories and experiment stations in most parts of the world and in many disciplines: breeding, physiology, microbiology, veterinary science, nutrition, food science, dairy science, and other fields. Water buffalo research is an area worthy of financial support by philanthropic institutions and international development agencies concerned with problems of food and resource shortages. The dominant role of the buffalo in the rural economies of Egypt and Asian countries offers the opportunity for buffalo research that can bring improvements quickly and easily to the rural poor. For other countries the water buffalo is an untapped resource, and they should test its productivity on native pasturelands, marshy lowlands, hot and humid areas where cattle do not thrive, and on areas prone to cattle diseases and parasites that are difficult to control.  </P>
1167<P ALIGN="JUSTIFY">Specific recommendations follow.  </P>
1169<P ALIGN="JUSTIFY">&nbsp;</P>
1170<P ALIGN="JUSTIFY">Comparison with Cattle</P>
1172<P ALIGN="JUSTIFY">Animal scientists worldwide should undertake trials to compare growth rate, feeding, nutrition, breeding, and other aspects of buffalo and cattle performance.  </P>
1174<P ALIGN="JUSTIFY">Cattle and water buffaloes are obviously different animals. Each has its own limitations and advantages, and each deserves to be studied in its own right. Perhaps the quickest way for animal scientists to experience for themselves the merits of the water buffalo is to conduct their own comparative trials with buffaloes and cattle in their areas. The results will provide local guidance and will help extend recognition of the buffalo's value, especially under difficult conditions where it may exceed cattle in productivity and profitability.  </P>
1176<P ALIGN="JUSTIFY">&nbsp;</P>
1177<P ALIGN="JUSTIFY">Germ Plasm Preservation</P>
1179<P ALIGN="JUSTIFY">Urgent action is needed, especially in Southeast Asia, to preserve and protect outstanding buffalo specimens.  </P>
1181<P ALIGN="JUSTIFY">In some countries (Thailand, Malaysia, and Indonesia, for example) buffalo populations are decreasing dramatically. High demands for meat are causing slaughter at younger and younger ages. Much of the meat is exported to restaurants and markets in Singapore and Hong Kong. Unfortunately, the largest and quickest growing animals are often selected for slaughter. This results in the loss of a major genetic resource, which is compounded by the practice of castrating the largest males to make them more tractable as work animals. Ten years ago in Thailand it was common to find buffalo weighing 1,000 kg; now it is hard to find 750-kg specimens. A similar situation exists in the Philippines where there is no dearth of good breeding stock, but butchers are paying such high prices that farmers are selling even quality animals for slaughter. In northern Australia, where some of the bulls weigh almost 1,200 kg, the largest animals are being shot for meat, hides, pet food, or sportsmen's trophies,  </P>
1183<P ALIGN="JUSTIFY">A large number of high-yielding buffaloes are taken each year to big cities in India (for example, Bombay, Calcutta, Madras) for milking. At the end of lactation many are returned to the villages, but many others are slaughtered, rather than being fed and retired. This creates a huge loss of valuable germ plasm. In many locations most of the largest animals have already been lost. Only urgent action will protect those remaining.  </P>
1185<P ALIGN="JUSTIFY">&nbsp;</P>
1186<P ALIGN="JUSTIFY">International Shipment</P>
1188<P ALIGN="JUSTIFY">Buffalo quarantine stations should be organized in "disease-free" areas to develop buffalo germ plasm pools for international exchange.  </P>
1190<P ALIGN="JUSTIFY">The importation of buffaloes presents difficulties for any government, researcher, or farmer wishing to obtain the animals for the first time or for breeding purposes. Quarantine laws make it extremely difficult and expensive to exchange genetic resources.  </P>
1192<P ALIGN="JUSTIFY">Australia is one of the few nations where there are large numbers of water buffalo in an area free of the major animal diseases. Papua New Guinea, </P>
1194<P ALIGN="JUSTIFY">Nigeria, Colombia, Venezuela, and other nations have taken advantage of this and have  imported Australian buffaloes. But Australian herds are all Swamp buffaloes(The island  of Guam is also a safe source of Swamp animals, although the feral herds there are  depleted, only 300 or 400 animals were left on Guam in 1978) and so breeding centers  should be set up also (in Sri Lanka and Italy perhaps) where importers can obtain  River-type (including Mediterranean) buffaloes.  </P>
1196<P ALIGN="JUSTIFY">Genetic Improvement</P>
1198<P ALIGN="JUSTIFY">Worldwide efforts should be made to select superior buffalo bulls and cows for breeding.  </P>
1200<P ALIGN="JUSTIFY">Performance testing, leading to the mass selection of superior animals, deserves high  priority. Virtually all buffalo breeding is haphazard and unplanned. Village animals graze  together and matings are usually not con" trolled, observed, or recorded. Thus, the full  genetic potential of the water buffalo is not being realized.  </P>
1202<P ALIGN="JUSTIFY">A massive selection program is needed to bring about genetic progress. For each breed,  bulls and cows with the potential for improving production of meat and milk and  increasing draft power should be identified and used for breed improvement. However,  the wide variations between the characteristics of individual animals may make  exceptional genetic advances difficult to achieve quickly.  </P>
1204<P ALIGN="JUSTIFY">Important traits for culling and selection include behavior, temperament, reproduction  rate, easy milk letdown, average daily gain in weight or weight at a given age, carcass  quality (for example, large hindquarters), and milk production, as well as strength and  endurance for work.  </P>
1206<P ALIGN="JUSTIFY">Crossbreeding of Swamp and River buffaloes is a potentially important route to genetic  improvement. The progeny reportedly show hybrid vigor (heterosis) in milking ability,  fertility, meat production, and working ability. Infusing genes for high milk production into  the Swamp buffalo, now used mainly for meat and work, creates the potential for a  triple-purpose animal.  </P>
1208<P ALIGN="JUSTIFY">The use of artificial insemination and deep-frozen semen should be a major help in  upgrading the buffalo. Moreover, the transport of live embryos (rather than neonatal  animals) for implantation in the uterus of surrogate mothers could be important for water  buffalo. It seems unlikely, however, that buffalo embryos can be implanted in cattle.  </P>
1210<P ALIGN="JUSTIFY">Most genetic selections should be made in Asia where 97 percent of the world's water  buffaloes are located. The improvements will depend on how accurately bulls can be  identified, selected, and mated. Performance and  progeny testing is sorely needed at research stations as well as "on the farm." Governments should also institute bull-loan or artificial-insemination programs as a means for upgrading the village herds.  </P>
1212<P ALIGN="JUSTIFY">&nbsp;</P>
1213<P ALIGN="JUSTIFY">Comparison of Breeds</P>
1215<P ALIGN="JUSTIFY">The relative merits of the various buffalo breeds should be determined,  </P>
1217<P ALIGN="JUSTIFY">Little or no information is available on the comparative performance of the different buffalo breeds in various environments, especially the 17 or so River breeds in the Subcontinent and the Egyptian and Mediterranean breeds. Comparison trials of the breeds and breed-crosses are needed in a wide range of climates from the humid tropical to the temperate. In addition, the cytogenetic, immunogenetic, and inheritance relationships of breeds should be clarified.  </P>
1219<P ALIGN="JUSTIFY">The panel encourages countries such as India and Pakistan that have a number of buffalo breeds (for example, Murrah, Surti, Jafarabadi, Mehsana, and Nili/Ravi) to set up experimental farms for scientific reproduction of superior specimens. Substantial research benefits as well as profitable economic returns from using and exporting some of them would be realized.  </P>
1221<P ALIGN="JUSTIFY">&nbsp;</P>
1222<P ALIGN="JUSTIFY">Meat and Milk Research</P>
1224<P ALIGN="JUSTIFY">Research and demonstration is needed to foster the widespread consumption of buffalo meat and milk.  </P>
1226<P ALIGN="JUSTIFY">Buffalo milk, cheese, and other dairy products are considered outstanding foods in all locations where they are produced. Taste tests so far have indicated that buffalo meat is similar or slightly superior to beef produced under the same conditions.  </P>
1228<P ALIGN="JUSTIFY">A specific need is to feed the male calves and use them for meat. Many are now slaughtered at a young age and light weight. Research that provides either a partial or complete milk substitute for feeding calves would have a major impact on meat supplies and farmer income. Diets being developed for calves in Egypt incorporate such ingredients as whey, soybean meal, corn flour (corn starch), and yeast.  </P>
1230<P ALIGN="JUSTIFY">Other research topics include:  </P>
1232<P ALIGN="JUSTIFY">· The effect of climate, thermoregulation, and wallowing on meat and milk production;  </P>
1233<P ALIGN="JUSTIFY">· The meat characteristics of each of the breeds and the differences between them,  </P>
1234<P ALIGN="JUSTIFY">· Milk production and quality for each of the breeds;  </P>
1235<P ALIGN="JUSTIFY">· Adapting buffaloes to machine milking by genetic selection or by designing new milking  machinery;  </P>
1236<P ALIGN="JUSTIFY">· Developing new or improved milk products (such as yogurt, cottage cheese, and hard  cheese); and  </P>
1237<P ALIGN="JUSTIFY">· Banking genetically superior germ plasm for later use.  </P>
1239<P ALIGN="JUSTIFY">&nbsp;</P>
1240<P ALIGN="JUSTIFY">Work Research</P>
1242<P ALIGN="JUSTIFY">The panel recommends research on new harnesses to replace the omnipresent yoke.  </P>
1244<P ALIGN="JUSTIFY">As already noted, the wooden yoke, which has not changed in 1,500 years or more, is an  inefficient harness. Research is needed to adapt horse collars, hames, breast straps,  and other devices for the buffalo. Because much of the farm power in Asia comes from  buffaloes, the impact of improved harness could be dramatic, widespread, and of  enormous value to millions of small farmers there. If the experiments in Thailand  described earlier are an indication, the farm power in Asia could be increased by 25  percent overnight with the adoption of an improved harness. The buffalo will continue to  be the small farmer's "tractor," so the benefits from improved harnesses are likely to  continue for a long time.  </P>
1246<P ALIGN="JUSTIFY">There are 13 million buffalo and bullock carts in India and 20 million Indians are engaged  in the business of road haulage. Application of appropriate technology would eliminate  the archaic wooden wheels, axles, and heavy carts and substitute lightweight carts,  perhaps with such features as metal wheels, pneumatic tires, ball bearings, and fixed  axles. With such improvements, loads might be increased and hauled over longer  distances at greater speed and with less work.  </P>
1248<P ALIGN="JUSTIFY">&nbsp;</P>
1249<P ALIGN="JUSTIFY">Trials in New Areas</P>
1251<P ALIGN="JUSTIFY">Testing of water buffalo production is needed in many areas where the animal is not  known.  </P>
1253<P ALIGN="JUSTIFY">A seemingly adaptable animal, the water buffalo should be productive throughout the  earth's warm temperate, subtropical, and tropical zones. Different breeds may adapt  differently to extremes of heat, humidity, and cold, and this needs further study.  </P>
1255<P ALIGN="JUSTIFY">The United States, the Mediterranean Basin of Europe, and some of the more temperate  European areas like southern England are worth considering for water buffalo trials. In the Southern Hemisphere River buffaloes are already found as far south as 25° latitude in Brazil's Sao Paulo State (where large herds are raised); an experimental herd of Swamp buffaloes has performed outstandingly in Brisbane, Australia (27°S); and there are a few Swamp buffalo in South Australia and Victoria (35°S or more). There is good reason to believe that water buffaloes may be productive in all of the states in Australia, New Zealand's North Island, South Africa, Argentina, and other warm temperate areas of the Southern Hemisphere.  </P>
1257<P ALIGN="JUSTIFY">The biggest void in the water buffalo map is virtually the entire continent of Africa. It seems a paradox that the buffalo-Egypt's most important domestic animal-is not farmed commercially in any other African country. Experimental herds have been introduced to Nigeria, Uganda, Mozambique, Tanzania, and other countries in the past, and the initial success of three of them is described in Appendix A.  </P>
1259<P ALIGN="JUSTIFY">The water buffalo, with its tolerance for heat, disease, poor-quality feed, and mismanagement, appears to have outstanding promise for African nations such as Sudan, Tunisia, Morocco, Senegal, and The Gambia as well as all nations south of the Sahara (Nambia perhaps being an exception).  </P>
1261<P ALIGN="JUSTIFY">More specific aspects of environmental tolerance deserving research attention are:  </P>
1263<P ALIGN="JUSTIFY">· The physiology of the buffalo's response to heat, cold, humidity, and other environmental factors;  </P>
1264<P ALIGN="JUSTIFY">· The effect of climate on growth, reproduction, milk production, health, respiration rate, behavior, and carcass quality; and  </P>
1265<P ALIGN="JUSTIFY">· Measurement of the calorific efficiency and chemical composition of all breeds of buffaloes and cattle to determine the environments best suited to each breed.  </P>
1267<P ALIGN="JUSTIFY">&nbsp;</P>
1268<P ALIGN="JUSTIFY">Nutrition Research</P>
1270<P ALIGN="JUSTIFY">Despite observations of the buffalo's ability to utilize poor quality forage, research is needed to learn how the animal does it.  </P>
1272<P ALIGN="JUSTIFY">This research should:  </P>
1274<P ALIGN="JUSTIFY">· Establish the buffalo's nutrient requirements by breed, sex, age, and weight for maintenance, growth, reproduction, lactation, and work;  </P>
1275<P ALIGN="JUSTIFY">· Determine voluntary forage consumption and the nutrient utilization of different forages in various stages of maturity;  </P>
1276<P ALIGN="JUSTIFY">· Examine rumen microbiology and fermentation, the rate of digestion, production, and absorption of volatile fatty acids produced in the rumen, and utilization of energy, nitrogen, vitamins, and minerals; </P>
1277<P ALIGN="JUSTIFY">· Develop milk replacements for early~weaned calves;  </P>
1278<P ALIGN="JUSTIFY">· Observe the current village-level feeding of low~uality forages to learn their nutrient requirements, nutrient deficiency diseases, and nutrient supplementation needed;  </P>
1279<P ALIGN="JUSTIFY">· Study the utilization of concentrated, high-energy feeds (especially byproduct feeds) to determine the upper limits of buffalo growth and productivity (milk, meat, and work) and carcass quality;  </P>
1280<P ALIGN="JUSTIFY">· Compare various breeds of water buffaloes and other ruminants to determine possible differences in nutritional requirements and performance; and  </P>
1281<P ALIGN="JUSTIFY">· Apply economic research to production practices, including night feeding of cut forage and the use of improved pastures.  </P>
1283<P ALIGN="JUSTIFY">&nbsp;</P>
1284<P ALIGN="JUSTIFY">Management</P>
1286<P ALIGN="JUSTIFY">Research to improve management practices could benefit small farmers, ranchers, and feedlot feeders alike.  </P>
1288<P ALIGN="JUSTIFY">Little is known about the farm management factors that influence water buffalo productivity. Studies and extension literature for farmers are needed on subjects such as:  </P>
1290<P ALIGN="JUSTIFY">· Proper fencing;  </P>
1291<P ALIGN="JUSTIFY">· Procedures for dehorning and for preventing horn growth in calves;  </P>
1292<P ALIGN="JUSTIFY">· Grazing management methods;  </P>
1293<P ALIGN="JUSTIFY">· Preservation of forages;  </P>
1294<P ALIGN="JUSTIFY">· Methods and effect of castration;  </P>
1295<P ALIGN="JUSTIFY">· Methods and effect of spaying;  </P>
1296<P ALIGN="JUSTIFY">· Breeding methods;  </P>
1297<P ALIGN="JUSTIFY">· Milking methods;  </P>
1298<P ALIGN="JUSTIFY">· Artificial insemination, methodology and use;  </P>
1299<P ALIGN="JUSTIFY">· Methods of handling animals under grazing conditions or in feedlots;  </P>
1300<P ALIGN="JUSTIFY">· Age for weaning under different conditions;  </P>
1301<P ALIGN="JUSTIFY">· Mineral and protein supplementation methods;  </P>
1302<P ALIGN="JUSTIFY">· Semen freezing;  </P>
1303<P ALIGN="JUSTIFY">· Ova transplantation methods;  </P>
1304<P ALIGN="JUSTIFY">· Cryobranding and other methods of animal identification;  </P>
1305<P ALIGN="JUSTIFY">· Control of internal parasites; and  </P>
1306<P ALIGN="JUSTIFY">· Disease prevention and treatments. </P>
1308<P ALIGN="JUSTIFY">&nbsp;</P>
1309<P ALIGN="JUSTIFY">Health</P>
1311<P ALIGN="JUSTIFY">Research is needed in areas where uncertainties about buffalo diseases are hindering  the animals' use.  </P>
1313<P ALIGN="JUSTIFY">The research should:  </P>
1315<P ALIGN="JUSTIFY">· Develop control and management practices to prevent specific infections and parasites  for buffalo groups such as calves, yearlings, heifers, pregnant cows, newly calved cows,  and bulls;  </P>
1317<P ALIGN="JUSTIFY">· Elucidate the factors (genetic, nutritional,management, disease) causing losses of  newly born calves;  </P>
1319<P ALIGN="JUSTIFY">· Prevent and control the major diseases and parasites of the buffalo: hemorrhagic  septicemia, brucellosis, tuberculosis, foot-and-mouth disease, sarcoptic mange,  fascioliasis, nematode parasites, rinderpest and "rinderpestlike" diseases, nephritis, and  conjunctivitis;  </P>
1321<P ALIGN="JUSTIFY">· Develop herd-health programs and specific disease-control programs for the various  production systems;  </P>
1323<P ALIGN="JUSTIFY">· Determine the level of susceptibility to trypanosomiasis, a disease that might mitigate  against introducing the animal widely to Africa; and  </P>
1325<P ALIGN="JUSTIFY">· Define the buffalo's role in malarial ecology.  </P>
1327<P ALIGN="JUSTIFY">&nbsp;</P>
1328<P ALIGN="JUSTIFY">Reproduction</P>
1330<P ALIGN="JUSTIFY">Research is needed to improve water buffalo reproduction.  </P>
1332<P ALIGN="JUSTIFY">Research topics should include:  </P>
1334<P ALIGN="JUSTIFY">· Physiology and deep-freezing of buffalo semen. (Although it is possible to freeze the  buffalo semen now, further improvements are needed to achieve higher conception  rates.)  </P>
1336<P ALIGN="JUSTIFY">· Incidence of sub-estrus and anestrus. This is fairly high in buffaloes. Work is needed to  determine the factors contributing to this problem and find solutions applicable in the  field. A simple, inexpensive test for the routine diagnosis of estrus is needed. It could  ensure that buffaloes are inseminated at the optimal time and could lead to the possible  synchronizing of estrus in groups of animals as well as the elimination of seasonal  breeding.  </P>
1338<P ALIGN="JUSTIFY">· Seasonality of breeding. Investigations are needed into seasonal effects on the intensity  and deviation of estrus in buffaloes. Most of the buffaloes in northern India and Pakistan,  for example, calve between July and December, causing scarcity of milk in the summer  season and a flush of production in the winter months (this phenomenon causes serious  marketing problems).  </P>
1339<P ALIGN="JUSTIFY">· Low libido and low semen yield in buffalo bulls. Semen yield in buffalo bulls is less than half of the yield from cattle bulls.  </P>
1340<P ALIGN="JUSTIFY">· Effect of season and other factors on semen quality.  </P>
1341<P ALIGN="JUSTIFY">· Variation in the freezability of semen from different bulls.  </P>
1343<P ALIGN="JUSTIFY">&nbsp;</P>
1344<P ALIGN="JUSTIFY">Dissemination of Information</P>
1346<P ALIGN="JUSTIFY">The panel recommends that two water buffalo publications be produced.  </P>
1348<P ALIGN="JUSTIFY">These should be:  </P>
1350<P ALIGN="JUSTIFY">· An international water buffalo newsletter. It is important to maintain communication among researchers working with the water buffalo in far flung research stations, universities, missions, and villages. Research findings may not be widely shared if technical animal science journals and the one or two national newsletters now available remain the only source of water buffalo information. A newsletter would bring together results from different parts of the world. It would provide rapid exchange of information as well as a forum for informal opinions, observations, and preliminary experimental data that are usually not accepted by journals.  </P>
1352<P ALIGN="JUSTIFY">· A formal journal of water buffalo research.  </P>
1354<P ALIGN="JUSTIFY">In addition, other methods for disseminating water buffalo information are to be encouraged. </P>

1373<P ALIGN="JUSTIFY">Water Buffalo in Africa</P>
1375<P ALIGN="JUSTIFY">For the water buffalo, Africa is the unknown continent. Apart from Egypt, where the  "gamoosa" is a major livestock resource, there have been few recorded experiences  with the animal in Africa. While this may be attributed to disease, chances are it is  because of historical oversight.  </P>
1377<P ALIGN="JUSTIFY">Small herds of buffaloes were recently introduced to Uganda, Tanzania, and Nigeria, but  because there were so few animals no firm conclusions can be drawn. Initial  observations, however, suggest that the water buffalo could have an important future role  in Africa, south of the Sahara. There seems little reason to believe that they won't thrive  there as they have done elsewhere in the tropics.  </P>
1379<P ALIGN="JUSTIFY">The following statements were provided by researchers involved in the enterprises.  </P>
1381<P ALIGN="JUSTIFY">&nbsp;</P>
1382<P ALIGN="JUSTIFY">Uganda</P>
1384<P ALIGN="JUSTIFY">"Uganda imported a herd of 12 buffalo cows and one bull in 1969. Grazed on poor-quality  unimproved pasture they received neither supplementary feeding nor any preferential  treatment over the East African zebus kept with them. The herd stayed 7 years at  Entebbe before being moved to another part of the country. They proved to be very  efficient converters of the low protein, high-fber fodder. During this time the herd grew to  40 adult cows and 2 bulls (all other steers were slaughtered). The cows calved every  year. The calves matured at 2 to 21/2 years; the zebu calves took at least 3 years to  mature. Buffalo calves were much heavier than the zebus of comparable age.  </P>
1386<P ALIGN="JUSTIFY">"The buffalo cows averaged 7 liters of milk per milking. In taste it was preferred to zebu  milk. Also, the quality of the meat after slaughter was much better than that of the zebus.  </P>
1388<P ALIGN="JUSTIFY">"A major advantage the buffaloes had over the cattle was that they were remarkably  unaffected by diseases endemic to the area. Apart from a few calves that died of  diseases that also killed cattle on the farm at Entebbe, the buffaloes resisted tick-borne  diseases, the biggest killers of cattle in Uganda, and were unaffected by the virulent  strains of East Coast Fever (Theileriosis), Uganda's most serious endemic animal  disease."(Information supplied by G. L. Corry, Director, Veterinary Research Services, Entebbe  Uganda)  </P>
1390<P ALIGN="JUSTIFY">&nbsp;</P>
1391<P ALIGN="JUSTIFY">Nigeria</P>
1393<P ALIGN="JUSTIFY">Early in 1976, 194 buffaloes aged 6-9 months were imported from the environs of Darwin in Australia's Northern Territory. The animals settled down quite well, and by the end of 1978 the stock population had risen to about 320, the adults weighing about 400 kg with about 80 percent fertility. The animals were in excellent health when an outbreak of streptothricosis occurred early in 1979. Because of the intractable nature of this rare disease of cattle, sheep, and pigs, the apparent spread of the disease in the confined area of the ranch, and the persistence of the organism, the animals were slaughtered(nformation supplied by Dr. J. E. Erhiaganoma, Chief Veterinary Officer, Ministry of Agriculture and Natural Resources, Benin City, Bendel State of Nigeria)..  </P>
1395<P ALIGN="JUSTIFY">&nbsp;</P>

1398<P ALIGN="JUSTIFY">Tanzania introduced 21 buffalo heifers and 2 buffalo bulls from Egypt in 1968 and 1970. By 1977 the herd had grown to 150 animals. They were kept at the Livestock Production Research Institute at Mpwapwa, a site representative of central Tanzania(Mpwapwa is located at an elevation of 1,000 m. It receives an annual rainfall of 700 mm during a single season between late November and early May. Mean minimum temperatures of 13°C occur in June, and mean maximum temperatures of 26°C occur in November). </P>
1400<P ALIGN="JUSTIFY">Over a period of 10 years the buffalo were studied and compared with crossbreeds of local Mpwapwa cows and Friesian steers. On average, the buffaloes conceived and calved 4 months earlier than the cattle, their mean calving intervals were about a month shorter, their birth and weaning weights were 1.5 times higher, and their daily weight gain was about double that of the crossbred cattle. The milk yield from the buffaloes was only about two thirds that of the crossbred cattle, but their rnilk's high butterfat content meant that the overall butterfat production was higher in buffaloes.  </P>

1407<P ALIGN="JUSTIFY">In a second study (Shoo, R A. 1980. A study of the performance of Egyptian water buffaloes. Student project, Animal Production Department, Faculty of Agriculture, Forestry and Veterinary Medicine, University of Dar-Es-Salaam, Morogoro, Tanzania.), 30 buffaloes and 34 Mpwapwa cattle (not the crossbreeds) were compared(Mpwapwa cattle are a Tanzanian breed with 55 percent Asian, 35 percent African, and 10 percent European blood). The calving intervals were 396 + 126 days for buffaloes and 437 + 109 days for cattle. The buffaloes first conceived at mean ages of 23-25 months (matings occurred in both wet and dry seasons), the cattle at 27-36 months. The buffaloes calved at 35 months, the cattle at 46 months.  </P>
1409<P ALIGN="JUSTIFY">On farms at Ruvu and Mabuki the calving rate was 63 percent, and the mortality rate 1.2-6.9 percent(Rakha, A. 1980. water buffalo Production, Tanzania. Report of the technical Cooperation Program TCP/URT/9002, Food and Agriculture Organization of United Nations, Rome, Italy). The buffalo's overall milk yields averaged 1,237 kg in 225 days, or 5.5 kg per day.  </P>
1411<P ALIGN="JUSTIFY">The results of the introduction of buffalo to Tanzania are considered "quite encouraging and the future of buffaloes in Tanzania will be bright." (Oloufa, M. M. 1981. The future of water buffaloes in Tanzania Paper presented at the Tanzania Society of Animal Production Eighth Scientific Conference, Arusha, Tanzania May 26-29, 1981.) Future plans call for increasing the herd to about 200 animals with a view toward establishing another buffalo herd. In addition, 5 buffalo sires have been selected in Egypt for shipment to Tanzania.  </P>
