I totally agree with Elkhunter, corn will have a bigger effect than protein for the cost and end result. Corn gives energy that helps deer to hustle protein. I have been told it takes at least 2 lb.s per day per deer protein. I would go broke fast for little help. I feed corn only. However, if ya got a lot of money to spend...then it doesn't hurt one way or the other.

How many deer are you feeding 100000 lb.s of protein to and how many acres are you hunting.

A somewhat interesting spin. Outside of penned deer, none will sit there and consume 2 pounds per day.

I agree with Hudbone...deer will not normally eat 2 lb.s...when I count deer I actually have measured how much corn deer consume in one setting. This helps to keep deer feeding about the same amount of time at each feeding area across the lease. I measured 1.45 lb.s / deer average over 30 days...that number was derived after two weeks of feeding for precensus each year before collecting data. A few days the numbers were a little higher around 1.5lb.s /deer.
A note: the dominate buck each day, when food is scarce, after eating, will run every deer (bucks & Does) out of the pen saving some corn for later...however, does would come in before bucks but sometimes after the bucks leave..so when the dominate buck leaves the pen empty, the does would come in and feed. The does would usually still leave some corn when they leave.
I asked biologist and feed stores how much of protein to feed....the results were 2 to 4 lb.s/day.

not each setting but per day.
