Well, I suppose if you donate the meat to charity you could write off the value of the venison. In my mind, the value of the venison consists of the cost of the bow, the arrows, the stands, the camo, the scents, the license fees, the processing fees etc. etc. If consider the true cost of venison, it's probably around $30 a pound by the time you consider all the above costs.
If venison is valued at $30 / pound and you donated say 100 pounds to a food bank, then you could write off $3,000 for those two deer you donated to the food bank since charitable donations are tax deductable.
