First off I wouldn't spend a lot of money on stuff with a picture of a big buck on it. This is not needed. Go to your local feed store or something similar. Deer like salt but it doesn't really do much for them nutritionally. However they do use a salt like all summer long and then shuts off in fall. Do some research on this and get prepared to get some out next February and youll be prepared for next spring/summer. If your looking for a mixture to help with nutrition find something or have a feed store mix it for you which is what I do. You shouldnt have more than 25% salt, and then about 18% calcium and 9% phos, also have them mix in many trace minerals, dried molasses, sulfur, etc. I get 50lb bag of a killer mixture for $15 a bag. Can't beat it. Nothing on the market compares to what I use and its 1/4 the price. Good luck with this! Its alot of fun to experiment with different mixtures and see what works in your area.
