Here is a pretty standard recipe.
1 part Di-calcium phosphate - This is a dairy feed additive bought at feed stores.
2 parts Trace mineral salt - The red and loose kind without medications.
1 part Stock salt, ice cream salt, or rock salt.
[font="Tahoma"]We use the same mix except we use a product called ADE minerals, in place of the trace minerals. It has all the same trace minerals but also has Vitamin A, D, & E. ADE Mineral Info Link The vitamins help the deer's body absorb the minerals.
Calcium & Phosphorus are needed for antler growth and milk production. The Di-Calcium Phosphate in the mix gives you these. (So does the ADE Mineral)
The salt has some nutritional value, but it is also an attractant. We also mix in some granulated or dried molasses for extra attractant power.
An updated price for this mix is around $70 for 200 lbs. of minerals ($85 if you add the molasses)
Di-Calcium Phosphate $24 for 50 lbs
ADE Minerals $20 for 50 lbs (you need two bags)
Stock Salt - $6 for a 50 lbs
(Dry molasses - $15 for 50 lbs)
It is still way cheaper than you can buy any of the premixed commercial minerals and you know it has everything your deer need! We have 2 licks on our property. We put 50 lbs out in each lick in the early spring and 50 lbs in each lick in the late summer / early fall.
To mix it, we take two 55 gallon trash cans and mix half of the minerals back and forth between the two until it is throughly mixed. Then we pour it on the ground and mix it into the dirt with a rototiller or shovels.
The following is a much better explanation that I quoted from this great article - http://missouriwhitetails.com/forums/vi ... pid=538271
I hope this helps!!!
I'll get some photos of our giant holes from our licks on here soon! [/font]
