He has free choice hay and a 1 1/2 acre dry lot to roam on. I fed him about 30lb this afternoon and he cleaned it up. I am afraid the cost of corn will just about break me in the next month...lol.The cattle that I have finished on shell corn in a self feeder got worked up to 27lbs/day. So I'm your close.
Make sure you have some type of roughage free choice for scratch.
