It is proposed that the composition of waterfowl diets would be expressed better in terms of metabolizable energy (ME) than in volume or weight. The use of formulas for estimating ME from chemical data of waterfowl foods is suggested. Average ME of three barleys fed to captive mallards (Anas platyrhynchos) was 3.173 kcal/gram dry matter; of four wheats, 3.526 kcal/gram dry matter; and of fall rye, 3.336 kcal/gram dry matter. Values for barley and wheat are comparable to published values determined for chickens; the value for rye fed to mallards is higher than values published for chickens.
