Cattle

Cattle, large ruminant mammal of the family Bovidae, most of which have been domesticated, including bison, buffalo, yak, zebu, and European cattle. By 2500 B.C. the Egyptians had several breed of cattle, which may have been used as draft animals and for leather. Their dung served as fuel and manure. Today, beef cattle (like Aberdeen Angus or Hereford) are square and heavily built commonly kept on poor grazing land, whereas dairy breeds (like Holstein or Guernsey) have good grazing. Recent breeds are mixed beef and dairy animals. A dairy cow can give as much as 14,000 lb (6,350 kg) of milk in 1 year.
