12 Management of Bulls at Custom Collection Studs

Veterinary Services for the Commercial Bull Stud
The semen collection – or “custom bull stud” – industry has markedly evolved during the time it has been in existence. Initially, a large majority of semen product was provided by large cooperatives or studs that maintained a large resident bull herd, catering primarily to the dairy industry and its needs. Most bulls in these studs were either purchased outright by stud management or secured by a long‐term lease, and thus breeders/owners very rarely realized the full rewards of their production successes. Beef cattle were processed as an aside, as the beef industry's use of frozen semen products was not widespread. As technology and breeding synchronization systems have evolved, the demand for semen in the beef industry has skyrocketed and custom bull studs have developed throughout the USA. These custom studs allow bull owners the opportunity to present herd sires with proven genetic merit, process and store these quality genetics, and retain ownership and possession of
