I have a horse in my barn (boarder) who is in good weight but is lacking the topline he ought to have. He is a nice imported Irish sporthorse, 15 years old. The family bought him when he was in training with a 4* rider to go foxhunting with the owner, and the current owner is a teenager going beginner novice. Obviously he is not going to be as fit and muscled as when we got him, but I keep looking at him like he needs to bulk up.
I don’t have good pasture quality. He is on free choice orchard mix hay in his stall during the day and out at night (again, poor grass so I supplement with a round bale). He gets 2 lbs purina safechoice senior twice per day. The other horses in the program all look good, but this one is lacking.
Thoughts on favorite supplements, if any? Or maybe add some alfalfa into his diet.
