He is currently on Alfalfa hay and senior feed. I've read info that goes both ways about the kind of hay to keep him on. I know to make any changes gradually, but I'm not sure how much of a change I need to make.
I've read both that the higher protein in alfalfa is important for an older horse, and that the higher protein is harder for an older horses system to process .
I'm planning to add beet pulp to his diet, and use that as a chance to add any supplements he may need, but I wanted opinions on what hays others have used that have worked for them.
I figure long term I'll likely end up using an alfalfa/bermuda mix, finding the middle ground that way.
