Growth Performances and Carcass Traits of Different Duck Breeds


  [Objective] To investigate the genetic differences of growth performances and carcass traits between different duck breeds and provide a reference for breeding fine ducks.[Method] Three kinds of healthy ducks including Cherry Valley duck,White Muscovy 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.……
