Beef cattle are cattle raised for meat production (as distinguished from dairy cattle, used for milk production). The meat of adult cattle is known as beef. There are three main stages in beef production: cow-calf operations, backgrounding, and feedlot operations. 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. ==Breeding and calving== Besides breeding to meet the demand for beef production, owners also use selective breeding to attain specific traits in their beef cattle. An example of a desired trait could be leaner meat or resistance to illness. 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 Cattle. The original Shorthorn was also a dual-purpose breed, but it diverged into two groups through selective breeding. Most beef cattle are mated naturally, whereby a bull is released into a cowherd approximately six weeks after calving period. However, beef cattle can also be bred through artificial insemination.〔 Cattle are normally bred during the summer so that calving may occur the following spring.〔 However, cattle breeding can occur at other times of year, such as late summer to early fall. Owners can select the breeding time based on a number of factors, including reproductive performance and seasonal cattle pricing.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「beef cattle」の詳細全文を読む スポンサード リンク
