We have had our steer since May he has had loose stools on and off since we've had him. He's on 18 lbs of full range show chow per day. He is gaining g an average of 2.65 lbs per day. We've given sulfa bolus a few times and it helps for a little while then he's at it again. We were giving 16 Oz of power fuel per day but stopped it 5 days ago thinking it could be part of the problem. He was doing well until today and it started again. Had stool tested last week and it was good but I am still concerned. Any suggestions? He's eating grass hay,as well
