AAFCO Standards
"Manufacturers can show their food meets AAFCO's standards for nutritional adequacy by calculations or by feeding trials. Calculations estimate the amount of nutrients in a pet food either on the basis of average nutrient content of its ingredients, or on results of laboratory tests—but not animal feed tests. If the calculations show that the food provides sufficient nutrients to meet the specific AAFCO nutritional profile referenced, the pet food label will carry a statement like: "(Name of product) is formulated to meet the nutritional levels established by the AAFCO (Dog or Cat) Food Nutrient Profiles for (specific life stage)."'
"Feeding trials signify that the manufacturer has tested the product (or a similar product made by the same manufacturer) in dogs or cats under strict guidelines. Products found to provide proper nutrition based on feeding trials will carry a statement such as: "Animal feeding tests using AAFCO procedures substantiate that (name of product) provides complete and balanced nutrition for (specific life stage)."'
Ingredients
Pet food ingredients must be listed on the label in descending order by weight. However, the weight includes the moisture in the ingredient, which makes it tricky to interpret. "A moist ingredient, such as chicken, which may be 70 percent water, may be listed ahead of a dry ingredient, such as soybean meal, which is only 10 percent water—yet the soy actually contributes more solids to the diet," says Susan Donoghue, V.M.D., owner of Nutrition Support Services, Inc., and past president of the American Academy of Veterinary Nutrition.
Similar materials listed as separate ingredients may outweigh other ingredients that precede them on the list of ingredients. For example, chicken may be listed as the first ingredient, then wheat flour, ground wheat, and wheat middlings. The consumer may believe that chicken is the predominant ingredient, but the three wheat products—when added together—may weigh more than the chicken.
The Right Stuff: Choosing a Good Pet Food
Pet owners should look for the manufacturer's telephone number. Only the manufacturer's name and address are required, but people should be able to call manufacturers to ask questions about their products, says Burkholder, and manufacturers should be responsive. "They will not tell you how much liver, for example, is in their product, because that's part of their proprietary formula. But they should tell you how much of any nutrient is in the product."
Some people prefer to pass up animal by-products, which are proteins that have not been heat processed (unrendered) and may contain heads, feet, viscera and other animal parts not particularly appetizing. But protein quality of by-products sometimes is better than that from muscle meat, says Burkholder.
"Meal" is another ingredient that some people like to avoid. In processing meat meal or poultry by-product meal, by-products are rendered (heat processed), which removes the fat and water from the product. Meat or poultry by-product meal contains parts of animals not normally eaten by people.
Providing precisely balanced nutrition is an investment in your pet's health. The right level of nutrients promotes good health, which impacts your pet's life expectancy and quality of life. Transitioning to the right food at each life stage (typically at ages 1, 5 and 7) helps meet the changes associated with aging.
