I. 2010 . Dietary lipid sources and vitamin E affect fatty acid composition or lipid stability of breast meat from Muscovy duck. Can. J. Anim. Sci. 90: 371Á378. A trial was conducted in order to assess the fatty acid composition and lipid stability of breast meat from Muscovy ducks (Cairina moschata domestica L.) fed a basal diet supplemented with 20 g kg (1 of soybean oil or fish oil and 30 or 230 mg kg (1 a-tocopheryl acetate (a-TA). A total of 120 one-day-old female muscovy ducklings were

... tributed over 12 pens (10 birds/pen). Growth performance traits were measured through the study. Each dietary treatment was randomly administered to three replicates when birds were 43 d until the slaughtering age of 66 d. Dietary treatments did not induce differences in growth performances and slaughter traits. Similarly, proximate composition and pH of breast muscle were not influenced by the diets. Significant increases in eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) contents in breast meat of ducks fed fish-oil-supplemented diets was observed. Lipid oxidation, expressed as thiobarbituric acid reactive substances (TBARS), of breast meat from birds fed 230 mg kg (1 a-TA-supplemented diets was significantly lower, compared with those fed diets supplemented with 30 mg kg (1 a-TA, both 1 and 7 d after slaughter.
