I have a 970 lb Chi/Maine market steer (short and stout, not tall and skinny). He is 10 months old, and I am currently feeding him 25 lb. of Associated 2 (grain for steers up to 1000 lb), 2 lb. Calf Manna, 4 lb. oat hay, and Ringmaster pellets ( a couple ounces) per day. He is short, and I would like him to continue growing taller until the fair in May. I realize that this is mostly up to genetics, but I've been told that if you feed over 20 lb. of grain, you wash out the steer's frame, and he will not grow much more. Is this at all true?
