Public Access to Feed Terms, Common or Usual ingredient Names, and Ingredient Definitions

To advance transparency and encourage consumer education about feed ingredients, AAFCO provides a free electronic version of the official feed terms, common or usual ingredient names, and ingredient definitions found in Chapter Six of the 2021 Official Publication (OP).

These feed terms, names, and definitions are typically adopted by state feed control officials and used as the regulatory basis to ensure all ingredients used in animal feed (including pet food) meet specific efficacy and identification standards. Likewise, feed manufacturers rely on these feed terms, names, and definitions to ensure compliance with the state regulations to distribute feed products in the marketplace. Finally, these feed terms, names, and definitions provide consumers with clarity and greater understanding about the ingredients in the feed they purchase.
