As a guy who raises beef cattle I wouldn't even consider slaughtering a beef that was stressed, sick or in poor shape. The same goes for wild game. It does effect the meat. A couple years ago while hunting Pe Ell South I had my daughter on 5 different branched bulls, all less than 70 yard with a muzzleloader and she passed on every one of them because they were barely able to move and emaciated. We would rather put them down and let the other critters eat them than waste a tag on an inedible (In my opinion) animal.
