Calf should be eating 25 pounds of grain right now. I would feed him 3 times a day. 2 scoops feed, 1 scoop Barley, 1 pound Stabilized rice bran, 3 ounces of the high octane each feeding. I would also get some good 3 way grain forage hay, and let him eat as much as he wants at night. We have found that it really helps drop the flank and give them a fuller deeper look, plus the added calories from the hay wont hurt. The hay is coarser than grass hay, works kinda like the beet pulp as far as fill.
