Judging by his pedigree, I would say he is a PHA carrier. Therefore, I'd say cut him, not only as a purebred Shorthorn and Maine breeder, but just as a cow calf producer. Either test him, or cut him.
he looks good. would be a nice steer not a breeding bull. but my question is where'd he get all of that waste on his front?? paddy and wmw do not give waste.
