The Muscovy duck （MD）, Cherry Valley duck （CVD） and their crossing mule duck were fed under the same raising condition for 10 weeks, the eareass traits, breastmuscle nutrients and meat characteristics of three breeds were measured at the age of 10 weeks. The results showed that the body weight of CVD and mule duck was significantly higher than that of MD at each weekend, the 10-week-old body weight of CVD, MD and mule duck was 2 446.4, 3 496.5 and 3 440. 0 g respectively. The dressing percentage and semi-eviscerated yield percentage of CVD were significantly higher than that of MD and mule duck, Lean percentage of CVD was the highest, and then was mule duck and MD. The subcutaneous percentage of CVD and MD was significantly higher than that of mule duck. The abdominal fat percentage of MD was significantly higher than that of CVD and mule duck. The breast muscle protein percentage of mule duck was significantly higher than that of MD and CVD. The breast muscle fat percentage of CVD was higher than that of MD and mule duck. The breast muscle water percentage of mule duck was significantly lower than that of MD and CVD. The breast muscle shear value of MD was significantly higher than that of CVD and mule duck.
