We have been feeding our bees Bee-Pro in the spring for a few years. = Bee-Pro is supposed to be a high protein pollen substitute. It is made = by Mann Lakes bee supplies. They claim that it promotes brood rearing = prior to the availablilty of natural pollen. I know that it keeps the = bees out of the farmers' cattle and pig feed. We don't get anymore = calls from farmers, upset about the bees in the spring. I'd like to know if anyong using this product has seen a noticable = increase in brood rearing that can be atributed to Bee-Pro. Has anyone = studied the contents of the product to see how the proteins compair to = real pollens. Any comments would be appreciated. Kevin Christensen
