AAFCO Ch6 chicken byproduct

AAFCO Ch6 definition 9.10 Poultry By-Product Meal consists of the ground, rendered, clean parts of the carcass of poultry, such as necks, feet, undeveloped eggs, viscera, and whole carcasses, exclusive of added feathers, except in such amounts as might occur unavoidably in good processing practices. The label shall include guarantees for minimum crude protein, minimum crude fat, maximum calcium (Ca), and minimum phosphorus (P), and the calcium level shall not exceed the actual level of phosphorus by more than 2.2 times. If the product bears a name descriptive of its kind (e.g., chicken by-product meal), the name must correspond thereto; it shall be suitable for use in animal food (Proposed 1985, Adopted 1990, Amended 2000, Proposed 2016 rev. 1, Adopted 2018 rev. 1). The AAFCO definition itself sets no fixed crude protein minimum or ash/calcium percentages — figures such as "60% CP minimum" are supplier or market specifications, not definition criteria. Poultry by-product meal is distinct from poultry meal (the corresponding flesh-and-skin rendered product) and is a legitimate, widely used ingredient in AAFCO-formulated foods.
