I have Brown on 14 pounds of alfalfa/bermuda pellets and 1 pound Integrity Lite Low Starch. While I have upped his feed by a couple of pounds a day I wanted to know what others expierences with Rice Bran and Biotin were. He is still slightly underwieght and we are working on his muscling up. His coat and hooves are also pretty dry and flaky. I wanted to add something and so far I have seen that biotin is good for the hooves and coat and Rice Bran adds fat with out adding carbs. There is a product by TDI horse feeds called Competition Conditioner that I was looking at. Would adding this stuff make my horse hyper? Has anyone used either product with any success for the reasons I am trying to use them. I was also looking at Equidae Coastal feed, it has rice bran as well. Sorry so long and thanks for reading.
