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.

These estrus synchronization protocols allow Fixed Time Artificial Insemination to be used, giving herd managers more accurate control. [6] The use of CIDRs with synchronization protocols helps improve reproductive performance by reducing the inefficiency associated with estrus detection.
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.
A breeding mount with built-in artificial vagina used to collect semen from horses for use in artificial insemination. Semen collection refers to the process of obtaining semen from human males or other animals with the use of various methods, for the purposes of artificial insemination, or medical study (usually in fertility clinics).
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]
Cows can be impregnated naturally (by a bull) or, as here, by artificial insemination. Since the 1950s, artificial insemination (AI) is used at most dairy farms; these farms may keep no bull. Artificial insemination uses estrus synchronization to indicate when the cow is going through ovulation and is susceptible to fertilization. Advantages of ...
