Interesting stuff Gflo, I had ideas about this but that is a good technical explanation. I think in free range deer, the odds of them consuming so much corn they die of too high blood acidity in unlikely. I could definitely see it happen in pen raised deer though.

My biggest concern is if you haven't been feeding the deer and then in February when they are about starved to death and then you start feeding them. You are going to do them more harm than good. Biggest reason, they are wasting all that time and energy consuming corn in which their stomach microbes aren't current ready to digest.

The same can be said you have have been heavily feeding deer corn and then all of sudden stop. They now have to switch back to an all natural browse diet, again they could face serious issues.

Tell me more about how deer digest protein? So it's a waste to feed them high protein pellets of even roasted soybeans?
