OBI tests approximately 700 bulls yearly and merchandises 300 of them through two all-breed sales held in March and October. To qualify for the sale, bulls must perform in the top 70% of their contemporary group and pass a breeding soundness exam. The October sale also features a select group of heifers consigned by OBI clients.

All bulls are tested according to the procedures recommended by the Beef Improvement Federation Guidelines for Uniform Beef Improvement Program.

Breeder-owned-and-financed, OBI’s governing board of directors consists of nine member breeds. Nonmember breeds are welcome to host performance tests at OBI, although the number of breeds and frequency of tests varies.
