随机选取浙川乌骨鸡健康母雏600只,测定0~18周龄体重和21~66周龄产蛋率,用Gompertz,Logistic,Bertalanffy3种生长曲线模型和伍德、杨宁、分室3种产蛋曲线模型分别拟合浙川乌骨鸡的生长曲线和产蛋曲线,并对拟合结果加以比较分析,结果表明,Gompertz模型能更好地拟合淅川乌骨鸡的生长曲线(R2=1.000),而杨宁模型最适合应用于淅川乌骨鸡的产蛋曲线拟合(R2=0.986)。
To explore the growth and laying rule of Xichuan black-bone chicken and rationally utilize the breed resource,600 females of newborn healthy Xichuan black-bone chickens were randomly select- ed as experiment materials. BW of 0 to 18 weeks of age and laying rate of 21 to 66 weeks of age were measured. Three growth curve models (Gompertz, Logistic, Bertalanffy) and three types of egg pro- duction curve models (Wood, Yang Ning, Compartment) were used to fit the growth curve and egg production curve of Xichuan black-bone chicken. Comparative analysis showed that Gompertz model could better fit the growth curve of Xichuan black-bone chicken(R2 = 1. 000) , and Yang Ning model was most suitable to fit egg production curve of Xichuan black-bone chicken(R2 =0. 986).
