Looking for information on worts in cattle, specifically worts on the penis of yearling bulls. Seems to be a concern in our area. I understand it is a virus and will go away in time, but with the risk of the bull infecting other cows. What effect will it have on their reproduction as well as his? How serious is this and should it be a concern when buying a new bull or herd sire???? The vets in our area seem to disagree with regard to this with some failing a bull on his breeding evaluation test (semen test) because of it. Others pass the bull and don't even mention it on the form. Any information would be greatly appreciated. Thanks.
