摘　　要：对Z型北京鸭3个品系与樱桃谷肉鸭的胸肌肌内脂肪含量的关系进行了比较分析。结果表明:北京鸭3个品系与樱桃谷肉鸭胸肌肌内脂肪含量差异显著(P<0.05),依次为Z4系>杂交系>Z2系>樱桃谷,胸肌肌内脂肪含量分别为6.74%、5.53%、4.69%、4.13%。综合本试验可得出:在瘦肉型北京鸭选育过程中,应增加胸肌肌内脂肪含量作为肉质选育指标,以避免北京鸭肉质的退化。Intramuscular fat contents of breast muscle in 3 strains of Z Pekin ducks and cherry valley duck were compared and analysed. The results showed that significant difference was found in intramuscular fat contents of breast muscle between 3 strains of Z Pekin ducks and cherry valley duck （P〈0.05）. The intramuscular fat content in turn was as followings：Z4 line Pekin duck,hybrid line Pekin duck,Z2 line Pekin duck and cherry valley duck,the corresponding value was 6.74% ,5.53% ,4.69% and 4.13%. It could come to the conclution that intramuscular fat content of breast muscle should be used as index to avoid meat quality degradation during the process of breeding of lean-fleshed Pekin duck.
