The water buffalo or domestic Asian water buffalo (Bubalus bubalis) is a large bovine animal, frequently used as livestock in southern Asia, and also widely in South America, southern Europe, northern Africa, and elsewhere.
In 2000, the United Nations Food and Agriculture Organization estimated there were approximately 158 million water buffalo in the world, with 97% of them (approximately 153 million animals) in Asia.[1] There are established feral populations in northern Australia, but the dwindling true wild populations are thought to survive in India, Bangladesh, Pakistan, Nepal, Bhutan, and Thailand. All the domestic varieties and breeds descend from one common ancestor, the wild water buffalo, which is now an endangered species.[2] The domestic water buffalo, although derived from the wild water buffalo, is the product of thousands of years of selective breeding in either South Asia or Southeast Asia.[3]
Buffalo are used as draft, meat, and dairy animals. Their dung is used as a fertilizer, and as a fuel when dried. In the Chonburi of Thailand, Pakistan, and the southwestern region of Karnataka, India, there are annual water buffalo races known as kambala. A few have also found use as pack animals, carrying loads even for special forces.
American bison are known as buffalo in parts of North America, but not normally in other usages; bison are more closely related to cattle, gaur, banteng, and yaks than to Asian buffalo. The water buffalo genus includes water buffalo, tamaraw and anoas, all of which are Asian species. The ancestry of the African buffalo is unclear, but it is not believed to be closely related to the water buffalo.

True wild water buffalo are thought to survive in Pakistan, Bangladesh, India, Nepal, Bhutan, and Thailand.
The IUCN Red List of threatened species classifies wild water buffalo (Bubalis arnee)[4] as an endangered species in Southeast Asia. They run rampant as wild animals in the Northern Territory, Australia, which is the only part of the world where they are legally hunted because of their large numbers there. The total number of wild water buffalo left in Southeast Asia is thought to be less than 4,000, which suggests the number of mature individuals will be less than 2,500, and an estimated continuing decline of at least 20% within 14 years (about two generations) and at least 50% within 21 years seems likely, given the severity of the threats, especially hybridization with the abundant domestic Asian water buffalo, leading to genetic pollution.[5]
Adult water buffalo range in size from 400 to 900 kg (880 to 2,000 lb) for the domestic breeds, while the wild animals are nearly 3 m (9.8 ft) long and 2 m (6.6 ft) tall, weighing up to 1,200 kg (2,600 lb); females are about two-thirds this size.[6]
River buffalo are usually black, have curled horns, and are native to the western half of Asia, whereas swamp buffalo can be black, white or both, with long, gently curved, swept-back horns; they are native to the eastern half of Asia from India to Taiwan.[1] The largest recorded horns are just under two metres long.[6]
The rumen (the first chamber of the digestive system of a ruminant) of the water buffalo has important differences from that of other ruminants.[7]
The water buffalo rumen has been found to contain a larger population of bacteria, particularly the cellulolytic bacteria, lower protozoa and higher fungi zoospores. In addition, higher rumen ammonia nitrogen (NH4-N) and higher pH have been found as compared to those in cattle.[8]
The classification of the water buffalo is uncertain. Some authorities list a single species, Bubalus bubalis, with three subspecies, the river buffalo (B. bubalis bubalis) of South Asia, the carabao or swamp buffalo (B. bubalis carabanesis) of the Philippines and Southeast Asia, and the arni, or wild water buffalo (B. bubalis arnee). Others regard these as closely related, but separate, species.[9] In 2003, the International Commission on Zoological Nomenclature ruled in favor of keeping wild water buffaloes a separate taxon from river buffaloes. They are now usually referred to as Bubalus arnee, though the former usage is still acceptable for authors who consider them conspecific.
The swamp buffalo has 48 chromosomes; the river buffalo has 50 chromosomes. The two types do not readily interbreed, but fertile offspring can occur. Buffalo-cattle hybrids have not been observed to occur, and the embryos of such hybrids do not reach maturity in laboratory experiments.[10]
Type Locality: "Habitat in Asia, cultus in Italia". Restricted by Thomas (1911a:154) to Italy, Rome, but Linnaeus' (1758) comment indicates Asia (India?).
Distribution: Bangladesh, Burma, Cambodia, India (survives in Assam and Orissa), Nepal, northern Thailand, Vietnam, and possibly at least formerly in Laos; domesticated in North Africa, southern Europe, and even England, east to Indonesia and in eastern South America; supposedly feral populations in Sri Lanka, Sumatra, Java, Borneo, Philippines and other parts of SE Asia; feral populations resulting from introductions in New Britain and New Ireland (Bismarck Arch., Papua New Guinea), and Australia.
The average lifespan in captivity is up to 25 years.
Asia is the native home of the water buffalo, with 95% of the world population, with about half of the total in India. Many Asian countries depend on the water buffalo as their primary bovine species. It is valuable for its meat and milk, as well as the labour it performs. As of 1992, the Asian population was estimated at 141 million. The fat content of buffalo milk is the highest amongst farm animals, and the butterfat is a major source of ghee in some Asian countries. Its success in Asia is evident by its extensive range. Both variants occur in Asia. River buffalo are found in elevations of 2,800 m in Nepal, and swamp buffalo are found throughout the lowland tropics. Part of their success is due to their ability to thrive on poor foodstuffs and yet be valuable economically. Moreover, they are much better suited to plough the muddy paddy fields, as they are better adapted than common cattle (Bos taurus) to move in swamps. In India, buffalo populations are thriving because they are considered to be similar to the cattle, which are sacred to the Hindus. Some ethnic groups, such as Batak and Toraja in Indonesia and the Derung in China, use water buffalo or kerbau (called horbo in Batak or tedong in Toraja) as sacrificial animals at several festivals. Especially in the Tana Toraja Regency, a local variety of water buffalo (tedong bonga) features a unique black and white colouration.
Swamp buffalo were introduced into the Northern Territory from Timor early in the 19th century as a food source and a beast of burden. They escaped, thrived and became feral, causing significant environmental damage. Buffalo are also found in Arnhem Land and the Top End. An estimated 350,000 buffalo were living on the floodplains of Arnhem Land and the Katherine region in the 1980s. As a result, they were hunted in the Top End from 1885 until 1980. The commencement of the Brucellosis and Tuberculosis Campaign (BTEC) resulted in a huge culling program to reduce buffalo herds to a fraction of the numbers that were reached in the 1980s. The BTEC was finished when the Northern Territory was declared free of the disease in 1997.[11]
During the 1950s, buffalo were hunted for their skins and meat, which was exported and used in the local trade. In the late 1970s, live exports were made to Cuba and continued later into other countries. Buffalo are now crossed with riverine buffalo in artificial breeding (AI) programs, and may be found in many areas of Australia. Some of these crossbreds are used for milk production.[11]
Melville Island is a popular hunting location, where a steady population of up to 4,000 individuals exist. Safari outfits are run out of Darwin to Melville Island and other locations in the Top End, often with the use of bush pilots. The horns, which can measure up to a record of 3.1 metres tip-to-tip, are prized hunting trophies.[11]
The buffalo have developed a different appearance from the Indonesian buffalo from which they descend. They live mainly in freshwater marshes and billabongs, and their territory range can be quite expansive during the wet season. Their only natural predators in Australia are large adult saltwater crocodiles, with whom they share the billabongs, and dingoes, which have been known to prey on buffalo calves and occasionally adult buffalos when the dingoes are in large packs.
Introduced into North Africa and the Near East by 600 AD, the water buffalo was brought to Europe with returning Crusaders in the Middle Ages, and herds can be found in Turkey, Bulgaria, Romania, Albania, Hungary, extreme south of Serbia, Austria and Italy. As in Asia, buffalo of the Middle East and Europe live on coarse vegetation on the marginal land traditionally available to peasants. They are an economic asset by serving as a protein source, draft animal, and storage of family or household wealth. In some areas, they also provide occasional recreation at annual racing festivals. These buffalo are mostly river buffalo; due to genetic isolation, they have adopted a distinct appearance. Buffalo milk is used for the production of buffalo mozzarella in Campania and many other locations around the world.
There are very limited commercial herds in North America, for yogurt and cheese products. In Gainesville, Florida, a University of Florida professor, Hugh Popenoe, has raised water buffalo from young obtained from zoo overflow. He uses them primarily for meat production (frequently sold as hamburger), although other local ranchers use them for production of high-quality mozzarella cheese.[12]
Water buffalo were introduced into the Amazon River basin in 1895. They are now extensively used there for meat and dairy production. In 2005, the buffalo herd in the Brazilian Amazon stood at approximately 1.6 million head, of which approximately 460,000 were located in the lower Amazon floodplain.[13] Breeds used include Mediterranean (from Italy), Murrah (India), Jafarabadi (India) and Carabao (Philippines).
In Argentina, many game ranches raise water buffalo for commercial hunting.
There are many breeds of domestic water buffalo.
Water buffalo have been domesticated for 5,000 years, and have become economically important animals. They provide more than 5% of the world’s milk supply and 20% to 30% of the farm power in Southeast Asia.[9] Milk from these animals is used by many human populations, and is the traditional raw material for mozzarella cheese and curd due to its higher fat content. In Africa and other locations, water buffalo milk is used for yogurt, as in Vermont, USA. The chief dairy breed of buffalo is the Murrah breed. Buffalo meat, sometimes called "carabeef", is often passed off as beef in certain regions, and is also a major source of export revenue for India, which has the largest population of buffalo in the world. In many Asian regions, buffalo meat is less preferred due to its toughness; however, recipes have evolved (rendang, for example) where the slow cooking process and spices not only makes the meat palatable, but also preserves it, an important factor in hot climates where refrigeration is not always available. Water buffalo horns are used for the embouchure of musical instruments, such as ney and kaval. Water buffalo hide provides a tough and useful leather, often used for shoes and motorcycle helmets. The bones and horns are often made into jewelry, especially earrings.
The water buffalo has promise as a major source of meat, even the milking ones. The water buffalo also is the classic work animal in Asia, an integral part of that continent’s traditional village farming structure, and also used for hauling cotton, pumping water in Pakistan and hauling logs in Turkey. The domesticated water buffalo is often referred to as “the living tractor of the East”, as it is relied upon for plowing and transportation in many parts of Asia.

Water buffalo spend much of their day submerged in the muddy waters of Asia’s tropical and subtropical forests. They have wide-splayed hooves, which are used to prevent them from sinking too deeply in the mud. These adaptations allow them to move in wetlands and swamps. Water buffalo also prefer to feed in grasslands on grass and forbs.
Water buffalo behavior sometimes differs from cattle. For example, most water buffalo are not trained to be driven. Instead, the herdsman must walk alongside or ahead of them. They then instinctively follow. They also rub against trees more often than cattle do, and they sometimes debark the trees, causing them to die.
The water buffalo has a reputation for being a sluggish breeder. Without reasonable nutrition, the animals cannot reach puberty as early in life as genetic capability would normally allow. Females normally produce calves every other year after gestation of 9 to 11 months. Young bulls typically remain with maternal herds, which consist of around 30 buffalo, for three years after birth. They then go on to form small, all-male herds.
The water buffalo may affect the environment in either positive or negative ways.
Wildlife and conservation scientists have started to recommend and use introduced populations of feral water buffalo to manage uncontrolled vegetation growth in and around natural wetlands. Introduced Asian water buffalo at home in such environs provide cheap service by regularly grazing uncontrolled vegetation and opening up clogged water bodies for waterfowl, wetland birds and other wildlife.[15][16] Grazing water buffalo are sometimes used in Great Britain for conservation grazing, for example to manage Chippenham Fen NNR. These buffalo have been found to be better suited to the wet conditions and poor-quality vegetation than many cattle.[17]
Currently, research is being conducted at the Lyle Center for Regenerative Studies to determine the levels of nutrients removed and returned to wetlands when water buffalo are used for wetland vegetation management.
However, in uncontrolled circumstances, water buffalo can cause environmental damage, such as trampling vegetation, disturbing bird and reptile nesting sites, and spreading exotic weeds.[9]
The world's first cloned buffalo was developed by Indian scientists from National Dairy Research Institute, Karnal. The buffalo calf was named Samrupa. The calf did not survive more than a week, and died due to some genetic disorders. So, the scientists created another cloned buffalo a few months later, and named it Garima. [18]
On 15 September 2007, the Philippines announced its development of Southeast Asia's first cloned buffalo. The Philippine Council for Agriculture, Forestry and Natural Resources Research and Development (PCARRD), under the Department of Science and Technology in Los Baños, Laguna approved this project. The Department of Agriculture's Philippine Carabao Center (PCC) will implement "Cloning through somatic cell nuclear transfer as a tool for genetic improvement in water buffaloes". "Super buffalo calves" will be produced. There will be no modification or alteration of the genetic materials, as in genetically modified organisms (GMOs).[19]
On 1 January 2008, the Philippine Carabao Center in Nueva Ecija, per Filipino scientists, initiated a study to breed a super water buffalo that could produce 4 to 18 litres of milk/day using gene-based technology. Also, the first in vitro river buffalo was born there in 2004 from an in vitro-produced, vitrified embryo, named "Glory" after President Gloria Macapagal-Arroyo. Joseph Estrada's most successful project as an opposition senator, the PCC was created through Republic Act 3707, the Carabao Act of 1992.[20]
