Wow- 10 lbs a day of Concentrates is way too much in my opinion too ! I agree with the other Heidi, lots of good quality forage and some concentrates. I like Dynamite vitamins and have used them for years, even became a Rep ! Eventually your horse will catch up, I think. I have seen horses fed too much concentrated food develop ephysitis ( spelling ) which is inflammation in the joints. Good Luck- and give him time to grow up. Happy Trails ! - Heidi Helly
