The National Research Council (NRC) of the USA is the working arm of the National Academies of the United States, carrying out most of the studies done in their names.
The Association of American Feed Control Officials (AAFCO) is a non-profit organization which sets standards for the quality and safety of animal feed (fodder) and pet food in the United States.
Most states have adopted the AAFCO models or use them in the regulation of animal feed/pet food.
