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 ...
Polled Holsteins were not fully recognized in the 1800s and were often placed in different categories then horned Holsteins. When record keeping began, polled Holsteins became more aware of and the understanding of the polled trait grew. The first polled Holstein sires used for artificial insemination (AI) started in the early to mid 1900s. [1]

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]
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 main cattle breeding method is using Artificial insemination (AI), which covers approximately 60% and Natural Breeding using improved breeds of stud bulls is practiced in remote areas and it covers approximately 25% of the total. Artificial Insemination (AI) is being practiced using locally produced semen and a limited amount of imported semen.
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]
Cattle only produce milk after calving, and so every dairy cow must produce a calf every year. In dairy herds (which in Britain and Ireland are almost all Holstein-Friesians), the best milking cows will normally be bred to a dairy bull, usually by artificial insemination (AI). The female purebred dairy calves from these matings will go on to ...
