Like other meats, duck is an excellent source of high quality protein containing a well-balanced array of amino acids. Duck also contains generous amounts of iron, phosphorus, zinc, copper, selenium, and lesser amounts of the minerals potassium, magnesium, vitamin E, A, C and folic acid. Duck is rich in faty acids. It is an excellent food for performance or highly active dogs or as a novel protein source for allergic pets. For pets that require a lower fat diet, duck can still be fed, although less often or in smaller portions per meal is recommended.
