Scoular and Cargill have some facilities not far from Dayton, but I have not contacted them to see if I can get defatted soybean meal. I am not sure where you are located, but there is a place not too far from Columbus you could call:

I will mix the soy meal with corn in Ohio and with Alfalfa hay in Ontario.
Everything molds eventually. Acorn rage tends not to mold quickly because it contains calcium carbonate. I assume cracked corn and soy meal are more prone to mold if they get a lot of rain. If the deer don't eat it and it gets rained on, i will simply stop feeding it for a while.
