Fancy large pony gelding, coming 6. There’s some TB in his bloodlines and he’s built more like a small horse than a pony. Needs to add about 50-75 lbs of lean muscle to fill out. Obviously, this is going to be a multi-year process of careful training and diet. This is a full lease situation for now.
In speaking to the owners of the barn where we would board, it sounds like they feed everyone TC Senior, beet pulp, rice bran, and a little flax seed. Hay is high quality but appears to be fed only while horses are stalled. Basically, concentrates would be upped if a calorie deficit occurred. I suggested maybe adding a small amount of alfalfa pellets or cubes and some oil instead of beet pulp or additional grain if the pony does turn out to need more calories. This is how the barns where I have worked in the past 5 years and the barn where my leased horse lives all feed. BO and hunter/jumper trainer both told me that the latter diet would make the pony too hot.
I’m just going to let it go because I don’t own the pony and likely neither way is 100% right for every horse. But because I’m curious and bored sitting here at home -what is the current thinking on diet for developing young horses? What are you feeding? I’m wondering if it isn’t somewhat discipline specific, at least in this area. The show hunter barns seem to feed basically as they when I was a kid 30+ years ago whereas the eventing/dressage/show jumpers seem to have backed way off on grain and feed a lot more forage foodstuffs and oils.
