1. origin of cattle Cattle were originally identified as three separate species. These were Bos Taurus the European or "taurine" cattle , the Bos indicus, the Cebu; and the extinct Bos primigenius Taurus the aurochs. The aurochs is ancestral to both zebu and taurine cattle. BY : alejandra pineda♥

2. Bos taurus. Like most domestic animals, Bos Taurus (domestic cow) is currently found throughout much of the world. The wild ancestors of cows were native to northern Africa, Europe, and southern Asia. Domestic cows are common and can be found throughout the world. Cattle are born and raised on rangelands. Rangelands are unfertilized, uncultured, and not irrigated. Also, they must contain adequate areas for grazing.

3. Bos indicus Beef production in New South Wales covers a range of climatic zones from subtropical through temperate to Mediterranean. Superimposed on the climatic variability The American Brahman is a B. indicus breed that has the typical loose skin, large ears and a hump over its shoulders. These have sweat glands in their skin that their B. Taurus cousins' don't. Their loose skin helps in better heat adapted because of the greater surface area for heat to be expelled; their ears work in the same manner.

4. Bos primigenius the ancestor of domestic cattle, was a type of huge wild cattle which inhabited Europe , Asia and North Africa but is now extinct; it survived in Europe until 1627. The aurochs were far larger than most modern domestic cattle with a shoulder height of 2 meters and weight of 1,000 kilograms The aurochs was regarded as a challenging hunting quarry animal, contributing to its extinction.
