I completely took Poco off of all grains or ration balancers. He is now on oats, alfalfa, and beet pulp. He also gets his biotin supplement and I just bought the flax seed meal a week and a half ago. Already I can see a HUGE change in his feet. I now only have to put his hoof conditioner on every 3 days. His feet are no longer dry and cracking. They look wonderful. I started to see a change only a few days after I started the flax seed meal.
That's great! I feed a similar diet, minus the beet pulp, and have had great results. I just throw in a vitamin supplement to cover all my bases, but they seem fine even when I run out for a while, lol.
Sometimes all that extra "stuff" does more harm than good!
