I should mention that last week we did begin changing his feed over to a low starch diet. We chose Purina's well solve to help maintain his weight but also to reduce his sugar intake. Here is the link: Purina Horse Feeds - WELLSOLVE
It is a complete feed with added supplements which support tissue repair. It also has a daily dose of biotin which will continue to help with transitioning to bare feet. He has always had a biotin supplement but now its all in one. I am interested to see if this will do anything. I also read an article months ago that young horses and their growth plates can be impacted by their protein intake. My vet did not seem to think that was his case and felt that his feed was appropriate. He has always been on LMF Developmental G, or Omolene 200.
