Can anyone give me any suggestions concerning weight loss in a horse? One of my horses is 24-25 years old and I noticed progressive weight loss in him. His teeth were floated last year and he is wormed monthly (rotating wormers). I came up with a concoction of beet pulp (soaked), Mazola corn oil, 10% sweet feed, and Calfmanna (a lot I know). He eats every bite. I have noticed some weight gain, but not enough to satisfy me. I can still see ribs and his spine. I am very disturbed by this and feel that everything I'm putting in him ought to have him big as the side of a barn by now (feeding this for several weeks now). He seems happy and does not appear to have any internal issues. I feel maybe I should switch to Omolene and maybe add the Calfmanna. Cost wise, maybe I am buying too much stuff for him. I just don't know. All of the others look great, it is just him. I've had horses for over 20 years and have had this horse a long time, but he is actually the oldest horse I've ever had and really don't know what to feed him I guess.
