We have a 11mo. Angus heifer that seems to have stopped growing and is just getting fat. we also have a 10mo. heifer that is on the same diet and is growing great. Their diet is 9 pounds of purina fitters edge, 3/4 pound of depth charge, ane 1/2 pound of sure champ fed twice a day. They are gaining an average of 3.5 pounds per day. What would you do with the heifer that is just getting fat?
