This is the carcass of a cow we euthanized. She was put in a cooler to age for a week before we processed her for sausage and ground beef. She was not sick, just consumed all of her energy trying to get unstuck from mud and her unborn calf.
After 4 days, her carcass was not setting up. I had to pay to dispose of this carcass.
I tried donating it to the Calgary Zoo, the wolf sanctuary, the Birds of Prey rescue, another wolf place… nobody would take it. The carcass was not rotten but didn’t have the right enzyme balance to set up.
The answer is you pay to dispose of it. Even the dog food and rendering plants get paid to take the dead horses and livestock ($300). I paid $50 which was cheaper than me going to get it and leaving it out for coyote bait.
Oh and that strange cut in the far side of the carcass - that is from doing a successful Texas C-Section.
