Hi! I had previously posted about my horse Charlie who had worms and a big, ribby belly... The worms are gone, the ribs aren't showing, but the big belly is still there. I also noticed that the other horse we have in the pasture is getting a big belly. As far as I can tell, they have a good amount of muscle on their top line, and as I said it's not worms. I'm not sure about the quality of the hay, but it seems nice and green. We just have round bales so they eat as much as they want, as well as a few lbs of Nutrena SafeChoice Original grain every day. We ride them regularly, out on the trail for several hours a week. They are not fat.
What can I do to get rid of the big bellies? I know that a "hay belly" is basically undigested hay, so is there some sort of supplement to make it digest faster? Or do I need to change something about their feed?
Thank you so much for any input!
