Question

You have a horse that needs to be fed a diet that consists of 78% hay and (100-78)% grain on a DM basis. You placed samples of the hay and grain in your oven at 220F for a few days until the samples were completely dry (they had reached a constant weight). Your results show that the hay was 84% DM and the grain was 92% DM. In order to feed these two ingredients in the correct proportions, what would the percentage of grain be on an as fed basis?
