Purina has some relatively good priced ones. We have used Fitter 35 (promotes lean Muscle, will help keep is front in leaner too) and Depth charge (helps fill out their gut, so they look a little bigger ribbed). I want to try Ultra Full this year, I will let you know what I think if I can get a hold of some. For multipurpose supplement we use Stand Alone, its pricey, but once they are used to it it will keep them on feed and we think it has helped our out. Good Luck!
