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.

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).
There are two routes of direct transmission for Tritrichomonas foetus between cattle: cow-to-bull or bull-to-cow. The most common route of transmission is from bull to cow. The cow can get infected either when naturally bred to an infected bull or when receiving semen from an infected bull during 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.
Electroejaculation is a procedure used to obtain semen samples from sexually mature male mammals.The procedure is used for breeding programs and research purposes in various species, as well as in the treatment of ejaculatory dysfunction in human males.
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 ...
