It sounds interesting. Humans are actually exceptionally bad meat animals as we take far more time to reach a reasonably harvestable size than animals we actually use for livestock. You'll get 60lbs to 80lbs of meat from a fully grown human, but it takes 15 to 20 years to get it. That is not a sustainable food source. That's why cloning and other technological solutions are used in so many Dolcett stories.
