Recipe and Label Analysis: Costco Kirkland Signature Adult Chicken, Rice & Vegetable Formula
To provide a detailed analysis, the “Costco Kirkland Signature Adult Chicken, Rice & Vegetable Formula” was selected as a representative of the product line. This formula boasts an estimated dry matter nutrient content of 28.9% protein, 17.8% fat, and 45.3% carbohydrates.
The ingredient list begins with chicken, a high-quality source of protein and essential amino acids. Following this is chicken meal, a concentrated protein source, and whole grain brown rice, providing digestible carbohydrates. Cracked pearled barley is another source of carbohydrates and fiber. Chicken fat, preserved with mixed tocopherols, is a good source of omega-6 fatty acids.
The formula also includes egg product, a highly digestible and biologically valuable protein source. Dried beet pulp, a source of fiber, is present, and while controversial to some, it is generally considered acceptable in moderate amounts for its digestive benefits. Potatoes offer a gluten-free carbohydrate source.
Fish meal is included as another protein concentrate, though the lack of specificity regarding the fish species is a minor drawback. Other ingredients include flaxseed, a rich source of omega-3 fatty acids, and dried yeast, which can be a nutritious additive and a source of B vitamins, though it may be a concern for dogs with yeast allergies.
The recipe also contains peas for carbohydrates and fiber, and chicory root, a source of inulin, acting as a prebiotic to support digestive health. Notably, the presence of chelated minerals indicates improved nutrient absorption. However, the inclusion of sodium selenite is noted as a potentially controversial form of selenium compared to more natural sources like selenium yeast.
