OK, so I bought my horse at the place he is boarded at now. He is a 16 yr old thoroughbred gelding with quite the sway back. He is a pasture horse( all day and night) and he has unlimited grass hay with some alfalpha along with grass in the pasture. In the morning he is feed Progressive ( a brand up here in the north, MN) for his top line 4 scoops. I am a Hunter Jumper just starting off and work him 3-4 days a week(due to gas prices) I am moving him closer to me but every stable I go to seems to feed such different things, ex.
Corn grain, sweet feed, Purina feed. I would like help on what you think he really needs and just not what the barns think they should get. He has been on this feed for a long time and now that he is getting ridden regullary his sway back is getting better, but he is my baby and I am afraid if he switches to something extreme he may colic? Any help is thanked in advanced!
P.s. I live in a cold state in the winter and he stays outside, so I don't want him to thin because of that.
