I need recommendations for a weight gain supplement/feed that will NOT make my horse "hot". My 5 year old paint mare has always been a little bit of a picky eater. Right now she is not quite where I want her to be weight wise (ribs are still covered and has nice topline coverage, just a little slender in the belly), especially going into the colder winter months. She has always been more on the "energetic" side and will run off what weight she does put on playing in the pasture. She is currently on 2 scoops (about 3 lbs each) of Purina Strategy a day, a complete mineral supplement, as much alfalfa hay as she can eat, and the little bit of pasture grass that is left for this time of year. I do not want to up her grain any more than it already is, as she is already a little "hot" due to the hay and amount of grain she is receiving. So are there any supplements out there that will help increase her weight without adding any more energy? I have already tried SmartPaks "SmartGain" powder and could not get her to eat it. In fact she went off her grain any time it was applied. Oil or pellet type feed would be preferred. I have used Nutrena EmPower with my old gelding, but it made him a litttle "hot" and he was definitely not a hot horse.
