Been icing the meat 5-10 days but wondering how it would turn out if we processed day of/next day.

I think any aging is good.
I would give it a day for sure, I have seen meat still twitching in the afternoon after a morning kill. An old timer told me "you need to give the meat a day to die"

I wouldn't. Give it a few days to relax.

I usually add ice at least twice, while keeping the bloody water drained off the meat, seems to me the more I'm able to let the blood settle out, the better the end product seems to be, but ymmv.

We do everything except grinding at home in the shop. I usually skin & quarter, then put everything in my shop fridge for 2 or 3 days to age...... Works for me!
(I've got it set up for catching draining blood)

After we finish trim out, wrap straps, steaks, & roasts, I take the stuff to be ground to a local processor and he does it by the pound.

Usually put ours in the freezer for a couple to 5 days at least before processing. Heard it is better to let all wild meats sit in freezer for 72 hours to kill off any bacteria.

I have processed quite a few and to be honest if you are going to freeze the meat I cannot really tell much difference in aging a few says or couple weeks with venison.

Ever notice how much blood is drained from the meat when you thaw it, doesn't really seem to matter if you soaked it for a week or processed it the same day it was killed, a lot more blood will drain from freezing than soaking.

I don't drain blood. It sits on ice to stay cold and give me the time I need to get around to processing or to get to the processing location.

Have been processing our own meat since I was a child. We have had meat sit in a fridge or on ice for up to two weeks and as little as zero and if your going to freeze it cant honestly say I notice a difference. We own the property we hunt on and have a processing facility on location. Our deer are typically processed the same weekend they are shot.

This is what we do too.

its nice to have the meat cold to work with. definitely want to get it cold so it won't spoil. but we've never had any need to bleed it or soak it in ice. I do not notice any difference in flavor or appearance. I would follow the rule of thumb that any good butcher shop would...keep it cold and keep it clean. don't do anything with it that you wouldn't do with a nice prime steak you just bought and you'll be fine.

field dressed ASAP, and cold/clean are most important. other than that I don't see any reason to let them wait other than just laziness.

I don't know about a taste difference, but in my experience, if you can age the deer for a day or two at the least, your meat will be more tender. I shot a doe down near Comfort last November on opening weekend. My buddy and I decided we wanted fresh venison for dinner that night so I kept one of the straps and a tender in the fridge and put the rest on ice. The meat we cooked that night was as tough as any venison I've eaten. I kept the quarters and everything else on ice for the next week, draining and adding ice each day until I had the time to process, package, and freeze it. Ate the remaining strap and tender about a month after freezing it and the difference was remarkable. It was much more tender. However, that may only relate to eating the meat fresh from the kill. It's possible that letting the meat age on ice or by hanging accomplishes the same thing as freezing does.

We usually butcher our deer and hogs the same day we shoot them. Cant say I've seen a difference in taste as we have used both methods.

Below is worth a quick read. Dry aging is the way to go, if you have the facilities to do so. I even use the frig in my garage to age when I am not at the ranch with the walk-in cooler.

we let ours stay on ice for a week draining off the water and adding ice twice a day. agree with others that it seems to be more tender.

I process mine as soon as I can. Sometimes the same day sometimes after it has been in cooler a week. I can't tell the difference personally but a lot of people swear they can.
