The objective of this investigation was to study the possibility to increase the docosahexaenoic acid (DHA) content of Muscovy duck meat by supplementing thew diet with the microalga Crypthecodinium cohnii. Two diets were provided to 58 male ducks, belonging to an Italian rural strain, from the 7th to the 10th week of life: a corn-soybean based diet as the control diet and the same diet supplemented with 0.5% microalga meal. Dietary treatment did not induce differences in growth performances and slaughtering yields. Similarly, chemical composition, colour, pH and oxidative stability of breast muscle were not influenced by the diet. DHA content of breast and liver was significantly increased by the experimental diet.
