The delivery of the nutrient is what is important.. With the market for deer nutrition, believe me, if the horse stuff was as good as the co-op folks say, they'd fence some deer and prove they have something equal to the deer nutrition products and cheaper and make a million$$$. It don't work that way. Co-ops are in the business of stock, to them the deer is a pest. I would bet 99.99% of those who work in the c0-ops haven't got a clue about a deers nutritional needs.
