Here is what I use and it makes 200 punds for $20 to $25:

2 parts Red trace minerial [unmedicated]

1 Part Stock salt

1 Part Dicalcium Phosphate [ Di-Cal ]

From what I have been told Salt is only used for taste and has no nutritional bennifits for the deer. The deer are getting all of the good stuff from the trace minerials and the the Di-Cal. The di-cal is used for rack development and milk production.

I have had extremely good luck with this mixture. A person has to remember that there are certain times of the year that deer do not use mineral licks very often but ther use them alot right after the rut and and during the summer when bucks are growing racks and does are caring young'ins and when does are nursing young'ins.

This mixture is cheaper than any commercial brand and I would put it up against any commercial brand.
