Don't know what bull You are looking at but unless the stud collects it themselves, quality is the least of your worries. And if they do, they have been there a long time, if quality was a problem, you would have heard rumors.
Universal in Great Falls is only a sales/distributor facilitity. The semen they handle is collected elsewhere. I have never ever heard any concerns except for NEEL Swoosh...I think his had to do with his owners trying to stretch the semen because he was collected as a yearling. If you are interested in a popular bull, you best hurry. I was in there last Monday and they had 20 tanks lined up for shipment that day.
