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.
Sperm sorting by flow cytometry is an established technique in veterinary practice, and in the dairy industry most female cows are artificially inseminated with sorted semen to increase the number of female calves (using sperm sorting is less common in other species of farm animals, however artificial insemination is common). [16] Artificial ...
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]
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. [18]
His book The Artificial Insemination of Cattle (1947) was the first comprehensive publication on AI published in England. Hammond founded the British Cattle Breeders Club in 1946 and was an active member in the early days of the European Association for Animal Production, serving on its Preparatory Committee.
For this reason, they require more land than other cattle operations, [7] such as feedlots, veal and dairy cattle production, or breeding operations that focus primarily on the management of bulls for artificial insemination. Pastures may be native or "improved" with forage designed to withstand grazing pressure and help animals gain weight ...
