Abstract
New Zealand Veterinary Journal 39, 3.5–6, 1991 For some considerable period it has been my intento to record a note of caution about the use of the serving capacity test(1) as a soundness examination for 2-year-old bulls. While the principles of the serving capacity test are well established and have proven in the field to be extremely valuable to the clinician, some care is required in its interpretation with 2-year-old bulls. This is specifically in the situation where certification for breeding soundness is required. Failure of a 2-year-old bull to perform (i.e. poor libido) at a single serving capacity test is not in my experience sufficient reason to issue a certificate of unsoundness for breeding purposes. This is based on my experience of testing about 200 bulls annually for 10 years.
