My 18 hd. Draft cross eats as much grass hay as he'll consume and gets about 3 lbs of Strategy a day, plus flax seed oil (they love it, lick the pan!) and Select vitamins. He's a really easy keeper, other than the amount of hay, he eats the same feed as my 13 hd. POA pony! My horses like orchard hay better than timothy and it's a little bit cheaper so that's fine with me!
