The AAFCO requirements were developed based on research from the National Research Council (NRC), described in their publication Nutrient Requirements of Dogs and Cats. In generating requirements, the AAFCO also considered recommendations by the European Pet Food Industry Federation. A pdf providing the AAFCO requirements and footnotes can be found online. The NRC publication can be purchased from a bookstore.
AAFCO requirements are applicable to both dog and cat food. This GoodGrub version only supports dog food recipes. Future versions may support cat food recipes.
