Operating since 1973, Oklahoma BEEF Inc. is now the second largest test station in the United States.
OBI tests approximately 700 bull annually and merchandises 300 of them through two All-Breed Performance Tested bull sales held in March and October. To qualify for the sale, bulls must complete testing with an index ranking in the top 70% of their contemporary group and pass a breeding soundness exam. The fall sale also features a select group of heifers consigned by OBI customers and testers.
All bulls are tested according to the procedures recommended by the Beef Improvement Federation Guidelines for Uniform Beef Improvement Program.
OBI is breeder owned and financed. A board of directors consists of representatives from nine member breeds. Non-member breeds are welcome to host performance tests at OBI, though the number of breeds and frequency of tests varies.
