I have a couple of does that have lost weight due to nursing fawns and I would like to add rice bran to their feed to promote weight gain. Anyone have a suggestion as to a product they will consume. I have tried a product from Manna Pro Max-E-Glo Meal in which our Breeder Buck and a few does will eat but not the does which need the weight gain. I have been feeding 5lbs of rice bran to 50lbs of feed is this correct or is their a better ratio.
