Dog-food products described as light, lite, or low calorie must meet specific calorie levels set by the Association of American Feed Control Officials (AAFCO), while dog foods named “less” or “reduced calorie” must show a percent reduction in calories as compared to a product in the same moisture-content category. The following table shows the guidelines as set by AAFCO for both dog and cat foods for determining whether a product can use the term “light.”
| Food Texture | Moisture Content | Dog Foods Maximum kcal ME/kg | Cat Foods Maximum kcalME/kg |
|---|---|---|---|
| Dry | less than 20% moisture | 3,100 | 3,250 |
| Semi-Moist | between 20 and 64% moisture | 2,500 | 2,650 |
| Canned | 65% or more moisture | 900 | 950 |
Like light versus reduced-calorie foods, lean or low-fat dog-food products must meet specific fat levels set by AAFCO, and less-fat or reduced-fat dog-food products need to show a percent reduction in fat as compared to a product in the same moisture category. AAFCO guidelines for dog and cat foods with “lean,” “low fat,” or similar words are shown in the following table.
| Food Texture | Moisture Content | Dog Foods Maximum % Crude Fat | Cat Foods Maximum % Crude Fat |
|---|---|---|---|
| Dry | less than 20% moisture | 9 | 10 |
| Semi-Moist | between 20 and 64% moisture | 7 | 8 |
| Canned | 65% or more moisture | 4 | 5 |
Ethoxyquin is a synthetic antioxidant (artificially manufactured from other elements) that is approved for different uses.
Ethoxyquin is approved and regulated by the Food and Drug Administration (FDA) and the Association of American Feed Control Officials (AAFCO) for use as a preservative in animal feeds.
Dog-food manufacturers have been using ethoxyquin to prevent rancidity and to maintain the nutritional quality of their products for more than 35 years.
Ethoxyquin remains stable at the high temperatures required to process dog foods during extrusion. It is important in protecting fats and oils from degrading, losing available calories, and becoming rancid.
Despite the fact that all studies conducted to date prove that ethoxyquin is safe for use in all animal foods when used at approved levels, rumors continue to circulate to the contrary.
Individuals who seek to discredit the use of ethoxyquin will often cite certain studies that showed toxic effects in animals fed ethoxyquin. What these individuals fail to point out is that the animals in these studies were given excessive amounts of ethoxyquin—20 to more than 50 times the maximum limit—before negative effects were exhibited.
