Poultry by-product meal consists of the ground, rendered, clean parts of the carcasses of slaughtered poultry, such as necks, feet, undeveloped eggs, and intestines - exclusive of feathers except in such amounts as might occur unavoidably in good processing practices. (AAFCO, 2003) It may contain parts from ducks, geese, turkeys, buzzards or chickens, etc. Poultry by-product meal is considered low quality and low nutrient, and is much less expensive than just chicken meat.
