As the others have already stated...corn is not going to do anything for the nutrition of your heard. I highly, highly reccommend using antlerking' s deer& elk pellets..I have seen this stuff grow some real monsters.. Talk about the nutritional needs..I don' t understand just how this stuff can help out so much. Anterking puts out a variety of products, and if you dont want to plant food plots, you can use the granular, or, like I said pelleted products. You can check this stuff out at
http://www.antlerking.com
Now honestly, normally I wouldnt put my rep. out on a limb for anything...but.. just check out some of the testomonials on this site. I have personally used this stuff... and these deer love it...they claim a bag last a whole month or so, but round here, its gone after a few weeks.
Also, if you really want to go cheap, you can use horse feed. Or there is a product that is put out by evolved habbitat called ' Rack Up" I' ve used it a few times as well, but not enough to tell if it helps or not---you can find this in the Bass pro catolog, or Cabella' s, or when it gets closer to fall, you can generally find it in your sporting goods section of Walmart!! Hope I' ve managed to help alittle in all my rambling

Good Luck,
Larry
p.s.---baiting isn' t legal here, but if the stuff is removed for a week(im pretty sure its a week) prior to hunting, it is perfectly legal in West Virginia.Also I hunt in a diffrent area from where I put it out, But in the same vicenity. In alot of states if the bait isn' t " in sight" of the stand it is legal. What I ussaully do is put the antlerking out right after the season, then just not put anymore out after early-mid August, which is around when I usually see the velvet come off. And the season starts in mid. October, which works out perfect!!
