Evaluating breeding soundness of bulls is an often neglected management practice. Producers may incorrectly believe that bulls that have previously proven fertile are of sound breeding value for the rest of their lives. They may also assume that new bulls are reproductively sound simply because of some vague or implied guarantee by the seller. Unfortunately, neither assumption is correct. Bulls that do not settle their share of cows early in the breeding season contribute to reproductive inefficiency. This can be as costly as dead calves, although much less dramatic.
