Perhaps such a system did exist somewhere in some bygone era—maybe in ancient India where milk was common but where cows or calves were never intentionally killed, and skin and carrion was sometimes taken from the corpse. I think most people would consider that non-objectionable—as did most ancient Jains, Buddhist, and Hindus, who believed in ahimsa.
But such a system does not, and probably can not, exist at any significant scale in the modern era. And while instant death is sometimes preferable to a "natural death"—I doubt those interested in "harvesting" the corpse would ever have any incentive to care about whether the death was "without much suffering".

I am. I work really hard to make sure my animals have the best death I can possibly give them. There’s horrific things happening in industrial meat production, no argument. That doesn’t mean that everyone who raises meat animals is uncaring.
