Growing up in PA deer hunting season was practically a holiday. We got the first day of the season off from school. It was much more humane for a deer to die quickly from a bullet through the heart than to slowly starve to death as the food supply dwindled with the onset of winter. If you had a choice between being shot and dying rapidly or slowly starving to death over the course of several weeks or months, which would you choose?
In a similar vein, race horses who are past both their racing and breeding primes are sometimes sold to meat packers in other countries, China was, maybe still is, a big market. The horses often ended up as dog food. Some years back Kentucky outlawed selling old horses to meat packers because it seemed inhumane. What happened was that the horses died pretty much the lingering deaths you describe, starvation, lingering illness and pain because there was no one to feed and otherwise look after them.
That would be the likely fate of billions of cattle,pigs, chickens, etc. if suddenly everyone stopped eating meat. No rancher in Nebraska or Montana, etc. is going to hire a private plane to fly over his cattle heard dropping hay bales to keep them from starving after a blizzard has covered up all their grazing land.
