Beef cattle are cattle raised for meat production (as distinguished from dairy cattle, used for milk production). The meat of cattle is known as beef. When raised in a feedlot cattle are known as feeder cattle. Many such feeder cattle are born in cow-calf operations specifically designed to produce beef calves. While the principal use of beef cattle is meat production, other uses include leather, and products used in shampoo and cosmetics.
Breeds known as dual purpose breeds are also used for beef production. These breeds have been selected for two purposes at once, such as for both beef and dairy production, or both beef and draught. Dual-purpose breeds include the Brown Swiss and many of the Zebu breeds of India such as Tharparkar and Ongole. The original Shorthorn was also a dual-purpose breed but diverged into two groups through selective breeding.
A steer that weighs 1,000 lb (450 kg) when alive will make a carcase weighing about 615 lb (280 kg), once the blood, head, feet, skin, offal and guts have been removed. The carcase will then be hung in a cold room for between one and four weeks, during which time it loses some weight as water dries from the meat. When boned and cut by a butcher or packing house this carcase would then make about 430 lb (200 kg) of beef.[citation needed]
