Studies suggest that Brahman cattle and its cross-breeds are more resistant to heat stress than the regular bos taurus breeds, [50] but it is considered unlikely that even more heat-resistant cattle can be bred at a sufficient rate to keep up with the expected warming. [58]
Cattle breeds fall into two main types, which are regarded as either two closely related species, or two subspecies of one species. Bos indicus (or Bos taurus indicus ) cattle, commonly called zebu, are adapted to hot climates and originated in the tropical parts of the world such as India, Sub-saharan Africa, China, and Southeast Asia.
This is a list of some of the cattle breeds considered in the United States to be wholly or partly of American origin. Some may have complex or obscure histories, so inclusion here does not necessarily imply that a breed is predominantly or exclusively American.
Small ruminants such as sheep and goats contribute approximately 475 million tons of carbon dioxide equivalent to GHG emissions, which constitutes around 6.5% of world agriculture sector emissions. [91] Methane production by animals, principally ruminants, makes up an estimated 15-20% of global production of methane. [92] [93]
Bos (from Latin bōs: cow, ox, bull) is a genus of bovines, which includes, among others, wild and domestic cattle.. Bos is often divided into four subgenera: Bos, Bibos, Novibos, and Poephagus, but including these last three divisions within the genus Bos without including Bison is believed to be paraphyletic by many workers on the classification of the genus since the 1980s.
Cattle are kept as livestock almost everywhere except in parts of India and Nepal, where they are considered sacred by most Hindus. Bovids are used as draft animals and as riding animals . Small breeds of domestic bovid, such as the Miniature Zebu , are kept as pets.
Many breeds of Turano-Mongolian cattle show a great hardiness and tolerance towards freezing temperatures as a result of adaption to harsh Asian climates.Especially the breeds of the Asian steppe and the Tibetan plateau are able to withstand temperature fluctuations from –50 °C to 35 °C (–60 °F to 95 °F).
Sanga cattle is the collective name for indigenous cattle of some regions in Africa. They are sometimes identified as a subspecies with the scientific name Bos taurus africanus . [ 2 ] Their history of domestication and their origins in relation to taurine cattle , zebu cattle (indicine), and native African varieties of the ancestral aurochs ...
