Many of the bulls will be used in the owners' herds during beef breeding season. However, they have the genetic merit to be used in many others as well. A beef bull may only be able to service 20 to 30 head via natural service during the breeding season. He will be able to service many more during the breeding season via artificial insemination.
The first recorded case of artificial insemination was John Hunter in 1790, who helped impregnate a linen draper's wife. [1] [2] The first reported case of artificial insemination by donor occurred in 1884: William H. Pancoast, a professor in Philadelphia, took sperm from his "best looking" student to inseminate an anesthetized woman without her knowledge.
The site opened in February 1943 as the Reading Centre for the Artificial Insemination of Dairy Cattle. [2] It had Shorthorn and Guernsey cattle. In January 1944 the site produced the world's first calf produced by artificial insemination, working with the Agricultural Improvement Council. [3] Another site had been opened at Cambridge in ...
Whereas in the past cattle had multiple functions, modern dairy cow breeding has resulted in specialised Holstein Friesian-type animals that produce large quantities of milk economically. Artificial insemination is widely available to allow farmers to select for the particular traits that suit their circumstances. [58]
Feeder cattle or store cattle are young cattle soon to be either backgrounded or sent to fattening, most especially those intended to be sold to someone else for finishing before butchering. In some regions, a distinction between stockers and feeders (by those names) is the distinction of backgrounding versus immediate sale to a finisher.
For the last five decades starting in the late 1960s, the main thrust of BAIF activities has been animal husbandry. This has principally involved artificial insemination (AI) of indigenous Indian cattle breeds with semen from bulls of high milk yielding European cattle breeds such as Jersey and Holstein Friesian.
