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.
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).
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.
These statistical methods influenced the artificial insemination stud rankings used in the United States. These early statistical methods are confused with the BLUP now common in livestock breeding. The actual term BLUP originated out of work at the University of Guelph in Canada by Daniel Sorensen and Brian Kennedy, in which they extended ...

This is a more exact but time consuming way to manipulate the cycle of multiple cows to sync up the timing of A.I. [5] Estrus synchronisation has major advantages in making artificial insemination more practical. Increasing the productivity of embryo transfer and artificial insemination is economically profitable as the costs associated with ...
Artificial insemination is a biotechnology widely used to improve production of cattle in agriculture, using selection methods that ensure optimal fertility and breeding outcomes. The fertility of the Charolais bull is an important factor as defective semen quality can contribute to reproductive failure, accounting for approximately 5-20% of ...
