Nutrition Fact #5

Formulation method v. feeding trial method: If your pet's food label says something to the effect of "This food is formulated to meet the nutritional levels established by the Association of American Feed Control Officials..." rather than "Animal feeding test using AAFCO procedures substantiate that this food provides complete and balanced nutrition...", it means that the food did not undergo actual feeding or digestibility trials. The formulation method is quicker and cheaper, but does not document the effect on animals.
