You are correct. There are not much for nutrients in corn untill it is cracked and dried. What i like to do with my corn when I use it, is run it through my mixer mill once. Just like when making feed and then bag it. I run at a lower RPM there for not to turn it into powder like feed. Seems to work pretty good but is work. Another thing I do is shell it. I have a corn sheller with a motor on it shell it into a metal garbage can and fill that half full, take a 4x4 and smash the hell out of the corn the best i can to crack as much as I can.. But mostly I use a good mix of deer food and corn.
