I have been wondering about that too. about corn and it passing through deer or not. for a fact corn is not nutritous. its a grain not a veggie . its not mineral pact .you say for a fact deer digest corn...so digesting corn isnt the question nutrients are . people use corn to bringdeer in, not to grow them .deer do seem to be atracted to corn gravel . i think thats all it is ,corn gravel, im going to plant some for kicks this year if i can handle the chore of watering it .not to provide nutrients but to bring them in to an area of wheat farms where their arent any deer... so true deer do digest corn and true its not worth much to over all deer nutrition. and true people mostly can not digest the plastic like hull of corn . later
