Summary:[ Objective] To investigate the genetic differences of growth performances and camass traits between different duck breeds and provide a reference for breeding fine ducks. [Method] Three kinds of healthy ducks including Cherry Valley duck, White Muscow duck and Jingjiang duck were selected as experimental animals. After they were fed under the same raising condition for 8 weeks, the body weight and meat traits were determined. [ Result] The growth performance had significant differences between three duck breeds （P 〈 0.05）; the Cherry Valley duck had the fastest growth, the Jingjiang duck grew most slowly, and the White Muscovy duck started to grow rapidly at the age of 4 weeks. The carcass weight, eviscerated weight, lean meat percentage, breast muscle rate, subcutaneous fat percentage and abdominal fat percentage of Cherry Valley duck were higher than those of other two duck breeds （ P 〈 0.05）, and the abdominal fat percentage of Jingjiang duck was 0. The eviscerated rate, breast muscle rate and dressing percentage of Cherry Valley duck were significantly lower than those of Jingjiang duck （ P 〈 0.05）. The carcass traits had differences between male and female ducks. [ Conclusion] The growth performances and carcass traits are different in these three duck breeds.
