The Association of American Feed Control Officials (AAFCO) was formed in 1909 to establish a framework for uniform regulation of the feed industry. Although not a government agency, AAFCO operates within the guidelines of federal and state legislation including laws administered by the Food and Drug Administration (FDA) and the U.S. Department of Agriculture (USDA).
AAFCO establishes standards or models for regulations aimed at ensuring that manufacturers provide clear, accurate, and consistent information about animal feed, including pet food.
Every year AAFCO issues an official publication called the AAFCO Manual. This manual, in addition to listing ingredient definitions and feed terms, addresses labeling issues such as label format, ingredient lists, nutrition claims, and guaranteed analysis.
These model regulations are different than laws. However a large number of state governments have adopted AAFCO pet food model regulations into state law.
The “AAFCO statement of nutritional adequacy or purpose,” also called a “nutrition claim” or “complete and balanced statement,” identifies which life stage and/or lifestyle the product has been approved for. Under AAFCO regulations, this statement must be substantiated by the manufacturer.
AAFCO recognizes three methods for substantiating the claim:
AAFCO has outlined very specific protocols, or guidelines, for conducting feeding tests. The protocols specify test criteria including such things as:
Each life stage has its own protocol. Life stages are the same for both dogs and cats and are defined as:
A pet food with an 'All Life Stages' claim can be used from weaning through adulthood. This claim is considered an unqualified (absolute) representation of nutritional adequacy. If substantiated through feeding trials, the protocol for gestation/lactation and growth must be performed sequentially, using the same group of animals.
AAFCO regulations state that specific wording must be used when a diet is intended for special nutritional or dietary needs that require the involvement of a veterinarian for diagnosis, management, and follow-up.
Understanding the AAFCO statements for nutritional adequacy can help customers choose a high-quality diet that provides complete and balanced nutrition for the appropriate life stage of their dog or cat.
Linoleic acid, a naturally occurring omega-6 fatty acid found in common pet-food ingredients such as corn and chicken fat, is a required nutritional component of the canine and feline diet.
Fatty acids are the building blocks of dietary fat and are formed by specific combinations of carbon, hydrogen, and oxygen.
Certain groups of fatty acids, called omega-3 (fatty acids in which the first double bond is located at the third carbon atom) and omega-6 (fatty acids in which the first double bond is at the sixth carbon atom), are particularly important to various functions in the cat's body.
The first double bond is located at the sixth carbon atom and, therefore, is an omega-6 fatty acid.
Omega-6 fatty acids are essential for maintenance of skin and coat condition, normal growth, proper membrane structure, and absorption of fat-soluble vitamins.
Linoleic acid is the most important omega-6 fatty acid because it cannot be synthesized by cats, and it is used to make other omega-6 fatty acids.
Cats also require arachidonic acid, because they cannot synthesize it from linoleic acid.
Most pet foods contain more than the required amount of linoleic acid. However, IAMS research shows that it is not just the amount, but the ratio of omega-6 to omega-3 fatty acids, that is most beneficial to cats.
The optimal omega-6:omega-3 fatty acid ratio to maintain a healthy skin and coat in dogs and cats is between 5:1 and 10:1, so five to 10 omega-6 fatty acids should be present for every one omega-3 fatty acid.
