Well, all things considered the Meat Plants are doing very well keeping up with the Nation. It is one thing to stand next to cattle staring you through the fence as they go up the ramp to the kill floor knowing that hours later they will be in the trailer on the way to NYC or Chicago Markets as processed meats in different cuts.
One other thought. NOTHING in those livestock is WASTED... NOTHING. If memory serves even the Hoof is used along with the hides and everything else.
What they DO do is try to keep certain guts OUT of the human food chain and send them in special trucks to ... dog and catfood plants to be processed into food for animals and pets.
Finally but not last, nerve material sometimes harbor sickness and think those are seperated from the meats and sent away to be processed.
