The water buffalo, also called domestic water buffalo or Asian water buffalo is a large bovid originating in the Indian subcontinent, Southeast Asia, and China. Today, it is also found in Europe, Australia, North America, South America and some African countries. Two extant types of water buffalo are recognized, based on morphological and behavioural criteria – the river buffalo of the Indian subcontinent and further west to the Balkans, Egypt, and Italy, and the swamp buffalo, found from Assam in the west through Southeast Asia to the Yangtze valley of China in the east.
Bubalus is a genus of Asiatic bovines that was proposed by Charles Hamilton Smith in 1827. Bubalus and Syncerus form the subtribe Bubalina, the true buffaloes.
The Highland is a Scottish breed of rustic cattle. It originated in the Scottish Highlands and the Outer Hebrides islands of Scotland and has long horns and a long shaggy coat. It is a hardy breed, bred to withstand the intemperate conditions in the region. The first herd-book dates from 1885; two types – a smaller island type, usually black, and a larger mainland type, usually dun – were registered as a single breed. It is reared primarily for beef, and has been exported to several other countries.
The domestic yak is a long-haired domesticated cattle found throughout the Himalayan region of the Indian subcontinent, the Tibetan Plateau, Northern Myanmar, Yunnan, Sichuan and as far north as Mongolia and Siberia. It is descended from the wild yak.
The Hereford is a British breed of beef cattle that originated in the county of Herefordshire, in the West Midlands of England. It has been exported to many countries, and there are more than five million purebred Hereford cattle in over fifty nations worldwide. The breed was first exported from the United Kingdom in 1817, initially to Kentucky, and spreading across the United States and Canada, through Mexico, to the great beef-raising countries of South America. Today, Hereford cattle dominate the world scene from Australasia to the Russian steppes. They can be found in Israel, Japan and throughout continental Europe and Scandinavia, in the temperate parts of Australia, Canada, the United States, Kazakhstan and Russia, in the centre and east of Argentina, in Uruguay, in Chile, and in New Zealand, where they make up the largest proportion of registered cattle. They are found all around Brazil and they are also found in some Southern African countries. They originally found great popularity among ranchers of the American Southwest, testament to the hardiness of the breed; while originating in cool, moist Britain, they have proven to thrive in much harsher climates on nearly every continent.
Dwarfing is a process in which a breed of animals or cultivar of plants is changed to become significantly smaller than standard members of their species. The effect can be induced through human intervention or non-human processes, and can include genetic, nutritional or hormonal means. Used most specifically, dwarfing includes pathogenic changes in the structure of an organism, in contrast to non-pathogenic proportional reduction in stature.
A bovid hybrid is a hybrid of two different members of the bovid family.
The Limousin, French: Limousine, is a French breed of beef cattle from the Limousin and Marche regions of France. It was formerly used mainly as a draught animal, but in modern times is reared for beef. A herd book was established in France in 1886. With the mechanisation of agriculture in the twentieth century, numbers declined. In the 1960s there were still more than 250 000 head, but the future of the breed was not clear; it was proposed that it be merged with the other blonde draught breeds of south-western France – the Blonde des Pyrénées, the Blonde de Quercy and the Garonnaise – to form the new Blonde d'Aquitaine. Instead, a breeders' association was formed; new importance was given to extensive management, to performance recording and to exports. In the twenty-first century the Limousin is the second-most numerous beef breed in France after the Charolais. It is a world breed, raised in about eighty countries round the world, many of which have breed associations.
Island gigantism, or insular gigantism, is a biological phenomenon in which the size of an animal species isolated on an island increases dramatically in comparison to its mainland relatives. Island gigantism is one aspect of the more general "island effect" or "Foster's rule", which posits that when mainland animals colonize islands, small species tend to evolve larger bodies, and large species tend to evolve smaller bodies. Following the arrival of humans and associated introduced predators, many giant as well as other island endemics have become extinct. A similar size increase, as well as increased woodiness, has been observed in some insular plants.
Insular dwarfism, a form of phyletic dwarfism, is the process and condition of large animals evolving or having a reduced body size when their population's range is limited to a small environment, primarily islands. This natural process is distinct from the intentional creation of dwarf breeds, called dwarfing. This process has occurred many times throughout evolutionary history, with examples including dinosaurs, like Europasaurus, and modern animals such as elephants and their relatives. This process, and other "island genetics" artifacts, can occur not only on islands, but also in other situations where an ecosystem is isolated from external resources and breeding. This can include caves, desert oases, isolated valleys and isolated mountains. Insular dwarfism is one aspect of the more general "island effect" or "Foster's rule", which posits that when mainland animals colonize islands, small species tend to evolve larger bodies, and large species tend to evolve smaller bodies.
The Australian Friesian Sahiwal, is an Australian breed of dairy cattle whose development commenced in the 1960s by the Queensland Government. It is a combination of the Sahiwal, a dairy breed of Bos indicus from Pakistan and Holstein breeds, designed for the tropical regions of Australia. Cows produce approximately 3,000 litres of milk per lactation under tropical pasture conditions with a high resistance to heat, humidity, ticks and other parasites.
The wild water buffalo, also called Asian buffalo, Asiatic buffalo and wild Asian buffalo, is a large bovine native to the Indian subcontinent and Southeast Asia. It has been listed as Endangered in the IUCN Red List since 1986, as the remaining population totals less than 4,000. A population decline of at least 50% over the last three generations is projected to continue. The global population has been estimated at 3,400 individuals, of which 3,100 (91%) live in India, mostly in Assam. The wild water buffalo is the most probable ancestor of the domestic water buffalo.
Sheep are quadrupedal, ruminant mammals typically kept as livestock. Like all ruminants, sheep are members of the order Artiodactyla, the even-toed ungulates. Although the name sheep applies to many species in the genus Ovis, in everyday usage it almost always refers to Ovis aries. Numbering a little over one billion, domestic sheep are also the most numerous species of sheep. An adult female is referred to as a ewe, an intact male as a ram, occasionally a tup, a castrated male as a wether, and a young sheep as a lamb.
The Hanwoo, also Hanu or Korean Native, is a breed of small cattle native to Korea. It was formerly used as a draught animal, but this use has almost disappeared. It is now raised mainly for meat. It is one of four indigenous Korean breeds, the others being the Chikso, the Heugu and the Jeju Black.
The West African Dwarf or Djallonké is an African breed or group of breeds of domestic sheep. It is the dominant breed of West and Central Africa. This breed is primarily raised for meat.
Cattle, or cows (female) and bulls (male), are the most common type of large domesticated ungulates. They are a prominent modern member of the subfamily Bovinae, are the most widespread species of the genus Bos, and are most commonly classified collectively as Bos taurus.
A gas giant is a giant planet composed mainly of hydrogen and helium. Gas giants are sometimes known as failed stars because they contain the same basic elements as a star. Jupiter and Saturn are the gas giants of the Solar System. The term "gas giant" was originally synonymous with "giant planet", but in the 1990s it became known that Uranus and Neptune are really a distinct class of giant planet, being composed mainly of heavier volatile substances. For this reason, Uranus and Neptune are now often classified in the separate category of ice giants.
Feed manufacturing refers to the process of producing animal feed from raw agricultural products. Fodder produced by manufacturing is formulated to meet specific animal nutrition requirements for different species of animals at different life stages.
The Niata or Ñata is an extinct breed of dwarf cattle from Uruguay and Argentina. It was observed by Charles Darwin in the 1830s. George Ernest Gibson bought two in 1889, one of which was exhibited at the Segunda Exposición Internacional de Ganadería y Agricultura in Buenos Aires in April 1890. By the early twentieth century it was nearly or completely extinct.
