We used him 2 years ago when that 1 blaze faced heifer sold thousands of units of semen, and the thing that I didn't like was that we got a buckler out of him out of a very structurally sound commercial Ext cow + his did throw all different types of calves for us. We did not have any goofy dispositions out of the bull, in fact I can get my hands on all 3 heifers that are out of him out in the lot and they have not been halter broke. I'm with Gidget on this one, use the semen on clean cows and test or breed any replacements clean. No big deal. JMO. Brent
