Since starting diet and supplementation based on ECIR protocols, my horse gets a little less than 1/2 cup 3 x a day. I weighed it once and it might be listed as weight in his case history. I eliminated soy products that I used to feed. It's always hard to say, but I believe it has been a good addition for him. He eats only soaked ODTBC with soaked beet pulp, and all of his dry supplements are sprinkled on top. No problems.
