I was at a horse show this summer and this woman was riding a beautiful Arabian with the shiniest coat I had ever seen. We started chatting and I asked her what sort of shampoo/conditioner/magic potion she used on her horse for such a shiny coat. She told me that she never uses any special soaps, etc and that it was all due to his feed. She says she feeds him a 10/6 horse feed. Does it really come down to the feed for a horse to have a shiny coat?
