The National Research Council (NRC) makes recommendations for nutrient requirements based on current research using purified diets for animals. In the US, the Association of American Feed Control Officials (AAFCO) uses the information provided by the NRC and adjusts these recommendations according to the lower digestibility and bioavailability of feed-grade ingredients that is often used in pet foods. The fresh, whole food ingredients we use at Tom&Sawyer more closely resemble the nutrient bioavailability and digestibility profiles from the NRC. Although there is a lack of Canadian regulation for pet food in Canada, at Tom&Sawyer we ensure all of our meals meet or exceed the recommendations from AAFCO and the NRC.
