I am not sure if you have had his teeth floated or not but I was having weight problems and I was feeding oats, alfalfa, and multi vitamins for the last three months. I purchased my guy a little underweight and though his weight is up now I now know the problem was with his teeth, I had them floated today and I am so happy I did because I learnt so much about him. He was in pretty bad shape in his mouth seems he has a bit of a overbite (about a quarter inch, not bad!) but I now know he has to be done at least every year, I feel this was the best investment in him I have made to date, I had to wait a while because equine dentists only come through town every three months or so but I was so happy that today was the day:) I notice a immediate improvement in his temperament and most of all the way he is chewing his food, I can't wait to ride him again in a couple days because I know he is going to be a dream to ride again, if you haven't had your horse examined yet don't waste time with feeding supplements make the call immediately if you think you may have a problem, a simple exam and float will tell you alot and make a big difference in your horses health, hope this helps!!!
Also I wouldn't guess on what to feed find out what your horse is lacking and go from there, I am now switching to rice bran and vegetable oil for weight gain.
