Did some more reshearch. The bucks skeletal system sacrifices minerals during the antler growth period and thus need all they can get during that period to produce the maximum set of antlers, then they need additional mineral/protein during the post rut and winter to re-build the skeletal system to get ready to start the whole process again. Genitics play a secondary role as without adequate nutrition growth will be marginal. "nutrition plays the biggest role in maximum antler growth". So I think if we provide year round additional high protein/mineral food source would be the best course to follow. Bucks need around 16% protein to achieve maximum antlers. Fall corn doesn't help bucks very much as its only 8% protein and maturing at the post antler growth cycle. It would help to leave standing corn for a winter food as it is high in calories. Most of the high dollar plot seed companies advertise around 30-38% protein for their products. Probably should continue this discussion in another forum.
