In the town I grew up in there was an abbatoir. Live animals in the back door, full retail butcher service out the front door. They also did custom slaughter and processing on a per pound/item basis.
Got word they closed a couple of years ago. Perhaps they couldn't compete. It's too bad really, I used to get beautiful farm fresh chicken roasters and other wonderful, unique products from there. They even had their own smokehouse for sausage, deli meats, bacon, hams.
