I got to thinking about this one the other day. I know some one with an arab that has a large hay belly. He could do with alot more muscle, has virtually no top line and very little muscle in the hips or neck. I'm very familiar with arabs and this guy definitely needs some work. He has been ridden sporatically throughout the winter, but with in the last week has been put on a steady riding schedule. Grass 24/7 turn out, with a little bit of senior feed. I know there are a few different causes for a horse with a big belly.
1. Worms. She claims the horse was wormed recently(just before purchase) by the old owner, but didnt see them do it. Its possible he may need to be wormed again
2. Diet. What causes a hay belly? Too little protein? Too much?
