zebu
A zebu (, or ; ''Bos primigenius indicus'' or ''Bos indicus'' or ''Bos taurus indicus''), sometimes known as indicine cattle, humped cattle or Brahman, is a species or sub-species of domestic cattle originating in South Asia. Zebu are characterised by a fatty hump on their shoulders, a large dewlap and sometimes drooping ears. They are well adapted to withstanding high temperatures, and are farmed throughout the tropical countries, both as pure zebu and as hybrids with taurine cattle, the other main type of domestic cattle. Zebu are used as draught oxen, as dairy cattle and as beef cattle, as well as for byproducts such as hides and dung for fuel and manure. In 1999, researchers at Texas A&M University successfully cloned a zebu.
==Taxonomy and etymology==
The scientific name of zebu cattle was originally ''Bos indicus'', but they are now more commonly classified within the species ''Bos taurus'' as ''Bos taurus indicus'', together with taurine cattle (''Bos taurus taurus'') and the ancestor of both of them, the extinct aurochs (''Bos taurus primigenius'').〔(【引用サイトリンク】url=http://www.departments.bucknell.edu/biology/resources/msw3/browse.asp?id=14200687 )〕 Taurine ("European") cattle are descended from the Eurasian subspecies, while zebu are descended from the Indian subspecies. "Zebu" may be either singular or plural, but "zebus" is also an acceptable plural form. The Spanish name, "cebu" or "cebú", is also present in a few English works.
