I took my reg. Murray grey bull to the vet today for a B.S.Exam. HE FAILED...He is a 13 month old murray grey bull. His scrotal cmf. was 36 which from what I understand is average. He produced sperm but the vet said it should have about three times as much little fishies in the pool. When do most people usually give bse test's. When I got home I put him out with my cow's. The vet said he may be able to breed about 5 or so cows... maybe, but obviously thats not what I'm looking for. I'm going to give him a few more months but in the meantime I've got to borrow someone elses bull so I dont miss my breeding season. That Suck's... Should I go ahead and take him back to the previous owner or should I stick it out for a while. He is a murray grey and from all I hear, they are supposed to be very fertile bull's. I bought him from a reputable breeder. I put him out with the cow's hoping they might stimulate him a little more. Any thought's or advise????????
