Poly Zinc and Poly Copper
I bought 10 lbs of each. I had heard good things about adding these two minerals to their diet. I have NO idea if it's a positive for my horses because they turn their noses up to it. Both products have a very strong smell. This was a $150 experiment that I don't know the results yet since they are not eating it. Before I purchased, I asked if it was palatable and did they suggest powder or pellet form for picky eaters (which they are not, but was trying to be proactive). I was told powder would be best. I mix it in their feed and a majority of it is left in the bottom of the feed tub. I tried mixing it with their beet pulp so it would 'stick'...they quit eating their beet pulp. 2 stars because I can't say it's not a good product, but I can't say if its helping either.
