Bos taurus (or Bos taurus taurus), typically referred to as "taurine" cattle, are generally adapted to cooler climates and include almost all cattle breeds originating from Europe and northern Asia. In some parts of the world further species of cattle are found (both as wild and domesticated animals), and some of these are related so closely to ...
Both scientific names Bos taurus and Bos indicus were introduced by Carl Linnaeus in 1758, with the latter used to describe humped cattle in China. [3]The zebu was classified as a distinct species by Juliet Clutton-Brock in 1999, [8] but as a subspecies of the domestic cattle, Bos taurus indicus, by both Clutton-Brock and Colin Groves in 2004 [9] and by Peter Grubb in 2005.

Crossbreeding Bos indicus and Bos taurus breeds maximises genetic gains through a process called heterosis (hybrid vigour), which increases the productive potential of the Charbray through a combination of Charolais and Brahman genes. [8] Complementarity can be exploited using crossbreeding methods in order to increase beef productivity. [9]
Before 1790, beef cattle averaged only 160 kg (350 lb) net. Thereafter, weights climbed steadily. [ 8 ] [ 9 ] Cattle breeds vary widely in size; the tallest and heaviest is the Chianina , where a mature bull may be up to 1.8 m (5 ft 11 in) at the shoulder, and may reach 1,280 kg (2,820 lb) in weight.

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.
A group of Asian indicine cattle ("Zebu", Bos taurus indicus) split off in around 700 AD (around the time of Islamization of the East African coast) and mingled with African taurines in different ratios, producing the four groups of African humped cattle. In Kim's own analysis, African taurines gained key adaptations in 16 genes for immunity ...
The Southern Yellow is a group of cattle breeds distributed in southern China. It is one of the three principal groups within the overall Chinese Yellow cattle population, which includes all indigenous Chinese cattle of both Bos taurus and Bos indicus origin, as well as hybrids between the two species; Chinese people traditionally do not distinguish between these.

The Droughtmaster is an Australian breed of beef cattle. It was developed from about 1915 in North Queensland by crossing zebuine cattle with cattle of British origin, principally the Beef Shorthorn. It was the first Australian taurindicine hybrid breed; [3]: 171 it is approximately 50% Bos indicus and 50% Bos taurus. [4]
