I have 2 boarders at my place that are not maintaining weight. Vet came out and floated teeth, did annual vaccines and coggins. I wormed with Equimax about a week or two ago (these are new boarders). The owner is wanting me to do power packs on both of them. The vet wanted me to up their grain (12 8) to 12 quarts a day which is 4 scoops. Owner wants me to pour corn oil on the feed. Frankly I'm not comfortable with either of these answers. But they aren't my horses and ultimately it is up to the owner. Is corn oil really that bad of an idea to fatten up horses? I know it's high in omega 6 which is proinflammation but what else?
