We don't actually replace any of the ration. We use one of the big cups, 32oz I think, 1 corn 2 water in a crock pot ever 12 hours. We put that on top of the ration if we a re trying to pour the fat on we also top that with a cap full of corn gluten (the powder stuff) and a fat product that Suthers makes (I can't think of the name right now I think it is actually a show pig product).oregondad said:Thanks Red, this is small frame steer that is doing very well. He is a picky eater and is getting tired of his feed, been on it for a long time now. We tried adding oil to his ration, he hated it. We have other steers going that love it. Just looking to try something new. How much should I start with if we cook up some corn, replace 1, 2, 3 pounds of the ration?
