corn doesn't offer nearly as much usable protein as it seems and there are plenty of things that offer as much (or more) protein as soy, as well as the good essential fatty acids. i would suggest peas, flax, sunflower seeds, fish... lots of options. the benefit of corn, really, is it's high fat and carb content for the ridiculously cheap prices.

i don't know of any feeds that exclude corn, but there are several that don't have soy. Countryside Naturals is the one i use. it's organic, so the corn isn't GMO and it's not the main ingredient.
wow, that table looks terrible, but i can't figure out how to fix it since it looks perfect in edit...
