Jersey Regional Sire Proving Groups

The American Jersey Cattle Association administers five (5) regional sire proving groups.

These breeder cooperatives sample and prove additional young Jersey sires in order to provide superior genetic material for the continued improvement of the Jersey breed. Membership in the group of choice is included in REAP herd enrollment. Herds not enrolled on REAP are also eligible to join a group to participate in sampling its bulls.

In general:

• The regional sire proving group identifies young registered Jersey sires worthy of sampling based on genetic evaluation of pedigree information, and acquires title.
• It arranges with a reputable AI organization to collect, process, store and distribute semen to the member.
• The group distributes 5 to 10 units of semen per sampling sire to an adequate number of randomly selected participating herds. Semen will be distributed at the rate of at least 10 units of sampling sire semen per 30 AI bred females or major fraction thereof in the participating herds each sampling year. For example a herd numbering 90 AI bred females would be allocated at least 30 units of sampling sire semen each year.
• The member agrees to participate in continuous official DHIA production testing.
• The member agrees to allow access of DHIA records through the Dairy Records Processing Center for the purpose of monitoring semen use, conception and offspring of the group's sires.
• The member agrees to participate in Type Traits Appraisal to obtain type information suitable for genetic evaluations.
• The member agrees to keep adequate records to ensure positive identification of daughters of bulls and their contemporaries.
• The member agrees to establish priority in the timely use of the distributed sampling sire semen.
• The member agrees to avoid premature culling of young sire daughters before adequate performance information is obtained.
