I don't mind buying young show calves. I feel like the sooner I can get them on feed the better. For our program, it works out. We start showing in May and hit it hard as we can all summer. When I say hard as we can, I mean as much as the steers will allow and still keep their ADG's and look good. After all, our main goal is to be good in the end. If I can start knocking the green off these calves early and start softening them up then the better they look starting in May. Getting a head start also allows us to be able to haul the calves without as much recovery time after a haul.
We start on a dry 35% corn ration with oats and cottonseed hulls and work our way up from there. It takes patients and you have to bring them along slowly. Obviously every calve is different so even at that early age we hand feed so we can accommodate each ones progress.
This being said, if a breeder has a good feeding program and is not just turning them back out on momma after the sell. Then he can keep them on his feed bill for another month or so.
