Bull Fertility and testing

A bull breeding soundness exam comprises 2 basic parts. Initially a health and physical soundness for mating exam is performed paying particularly attention to leg and joint conformation, body condition and structure of the internal and external genitalia. The second check looks at semen quantity and quality and sperm morphology (the structure of the sperm).

This exam gives an assurance that at the time of the exam, the bull was considered either fertile or sub-fertile. A sub-fertile bull may need follow up testing or considered unable to perform normal mating function and may need to be replaced.

Other services such as vaccination and pestivirus testing can also be performed at the same time. We recommend all bulls be vaccinated for Leptospirosis, Vibriosis and Pestivirus (BVDV) and be tested to ensure they are not Persistently Infected (PI) with Pestivirus.
