The goal in beef cattle breeding is the production of animals that make rapid and efficient gains and have desirable conformation. Performance testing has recently been advanced as a means of identifying individuals possessing superior productive qualities and as a means of evaluating sires for transmitting these qualities to their offspring. This report gives the results of performance tests conducted with Hereford and Shorthorn calves fed over a constant time period as well as the results of a supplemental study undertaken to gain information that might add refinement to the evaluation of gains in beef cattle.
