| 摘 要： | [目的]分析半番鸭不同组合及其亲本的生长性状及发育曲线。[方法]以樱桃谷鸭、金定鸭、苏牧麻鸭和白羽番鸭为亲本，杂交组配成3个杂交半番鸭，采用3种不同生长曲线模型对7个群体体重进行拟合，比较半番鸭及其亲本的生长性能。[结果]10周龄鸭体重比较表明，4个亲本鸭体重大小依次是樱桃谷鸭〉白羽番鸭〉苏牧麻鸭〉金定鸭，3个半番鸭“番金”、“番樱”和“番苏”鸭10周龄体重分别有30．33％、12．8％和22．04％的杂种优势率。3种模型中以Gompertz模型的拟合效果最佳，其拟合参数比较表明，半番鸭的极限体重、拐点体重、最大周增重和拐点时间均较亲本有大幅提高，“番樱”鸭、“番苏”鸭绝对生长速度也有明显的杂种优势。[结论]该研究为开展肉鸭的杂交育种工作提供理论数据。

| Abstract: | [Objective] The study aimed to analyze the growth performance and developing curve of the different combination of mule ducks and their parents.[Method] With the ducks of Cherry Valley,Jinding,Sumuma and White Feather muscovy as parents,3 crossbred mule ducks were bred,the weight of 7 populations were fitted by using 3 different growth curves to compare the growth performance of mule ducks and their parents.[Result] The comparison on body weight for 10-week-old ducks showed that the weight of 4 parent ducks... |
