[QUOTE="Dega Moo, post: 1013727, member: 19930"] So this vet tested your bulls semen two different times and called the bull unsound both times? Were you there during the sample and test? Was the sperm just not as active as the vet expected or did the bull test fully sterile? Our bulls need to fail three samples before we cull them based on a microscope test. Not sure of the percentages, but the difference between a highly motile sperm sample and less motile sperm is pretty clear and there's a break point where doc suggests culling. Of course improper handling of the sample can impact the results, typically a temperature shock can kill some or all of the sperm. On the other hand, did you test after the bull had run with the girls or did you leave him in after the test and prior to culling him? It is possible for a stressful event to impact a bulls sperm motility and within 90 days return to normal. [/QUOTE]
