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]
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]
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.
With the aim of improving breeds and dissemination of information, CIRB has sold over 1,000 bulls, conducted ~200,000 artificial insemination in the field for the farmers' buffaloes with a 41% conception rate, distributed ~520,000 progeny tested frozen semen kits to 45,000 farmers and over 250 institutes, imparted training to several thousand ...
Artificial insemination technologies were now the main practice of crossbreeding cattle breeds. The majority of these resulting breeds share common traits relative to market requirements such as high growth rates, greater meat yields per carcass and heat and drought resistant capabilities. [ 3 ]

After the Second World War, artificial insemination became common in cattle and pig breeding. As a result of these developments, a limited number of transboundary commercial breeds, such as the Holstein cow and Large White pig, have become very widespread and nowadays increasingly dominate livestock production globally. [6]
The semen of a son of this latter bull is collected in the artificial insemination center of Saint-Symphorien, at the request of the Livestock Institute. Today, the semen of 28 bulls is stored and available for artificial insemination. [14] The inbreeding rate among females is only 1.8%, which is very low for a breed with a small population. [20]
