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).
The early artificial insemination organizations were largely farmer-owned cooperatives. The first such cooperative in America was organized at Clinton, New Jersey, through efforts of Enos J. Perry, Extension Dairyman, New Brunswick, and began operations May 17, 1938. It began operations with 102 members and 1,050 cows enrolled.
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.
In cattle, CIDR-Bs are often used with synchronization protocols. The product label typically indicates that, in conjunction with an appropriate synchronization protocol, CIDRs should be left in for 7 days. [2] Ovsynch is a particular protocol that is often followed. [5]
Cattle, sheep, and goats are sometimes dehorned [1] [2] for economic and safety reasons. Disbudding is a different process with similar results; it cauterizes and thus destroys horn buds before they have grown into horns. Disbudding is commonly performed early in an animal's life, as are other procedures such as docking and castration. In some ...
The country of Lithuania has banned the practice due to their belief that the procedure is inhumane. [6] There is some evidence that elastration is more painful if carried out on older animals, [7] although much of the immediate pain of application can be prevented by injection of local anaesthesia into the scrotal neck and testicles.

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 ...
