The Bull Breeding Soundness Examination and Its Application in the Production Setting.

breeding soundness for several reasons and at several times during their life span. These include before sale for the reason of affirming their sale ability or before a breeding season to determine their readiness for breeding. Bulls may also be evaluated for diagnostic purposes. The breeding soundness examination (BSE) is universally promoted as an important management tool, but there continues to be a level of inconsistency in its performance. A complete bull BSE consists of a thorough physical examination including internal and external reproductive tract, measurement of the circumference of the scrotum and evaluation of individual sperm motility and morphology.
