Over a Thousand BSE's Using the New Form

Abstract

Beginning in the Fall of 1992 the Society for Theriogenology adopted a new form for evaluation of breeding soundness of bulls. To be a satisfactory potential breeder under these guidelines, a bull must pass all four parts of the examination. The four parts consist of an acceptable physical examination, minimum scrotal circumference based on age, minimum progressive motility of 30%, and minimum morphology of 70% normal cells. Failure to meet the standards of any portion of the examination means unsatisfactory or deferred classification. The three possible classifications are satisfactory potential breeder, unsatisfactory potential breeder, or deferred classification. Deferred classification replaced the old classification of questionable potential breeder and allows for reevaluation at a specified time for conditions which might improve.
