Commercial dry aging of venison is done between 33 and 37 degrees, typically 5-8 days. Wet aging is more variable depending on methodology.
There was an excellent article in Forbes online magazine this week about a Texas purveyor of antelope meat that described their aging process. Because they are a meat producer, not a hunting outfitter, they have a mobile butchering facility, drive it out into the ranch lands to where they are harvesting, use sharpshooting rifles to drop the antelope where they stood, no running, then immediately process the game on the truck before it goes to a combined dry + wet aging that involves a total of 25-26 days. Apparently their products are pretty tasty.
