Most backyard animals, like pigs, turkeys, and many varieties of cattle, sheep, chickens, ducks and geese would not exist without our omniverous nature. I see no moral ambiguity in raising animals for meat. It is not a stretch to say this, they rely on us to feed, shelter, love and protect them, and in exchange, we eat a select number of them. I see it as much nicer than how wolves, cats, or other carnivores and omnivores interact with their food. I would rather my food animals grow comfortably, well cared for with a humane ending, than to struggle with life to be ripped apart by some hungry predators, who proceed to decimate extra for sport. I've had friends that had sheep killed for sport by wolves, where the wolves obviously tortured the ewe before tearing her up, and only eating the lamb in her belly and leaving the rest to rot. It is not immoral to eat meat raised with care and love.
