Kim asks about supplements/feeding program for her colt…

What would you recommend feeding a 10 month old colt?  He was not properly looked after before my friend got him. I think she over wormed him etc.  He coliced.  The vet said his system was over stressed.  Put him on an ulcer medication.  She is looking for a nutrition program that will make sure he has all the vitamins/minerals etc for a growing baby.  She would like to take him off the mare and foal product that has molasses, corn etc. I have two months left of my other supplements and them I want to order your feeding program.  We also have a quarter horse that has terrible feet. 

Any recommendations?  

Thanks, Kim
