摘要
为探索京海黄鸡生长发育规律和合理利用种质资源,本研究随机选取京海黄鸡母鸡300只,测量0~35周龄体重和19~66周龄产蛋率,用Logistic、Bertalanffy、Compertz3种生长曲线模型和伍德、杨宁、分室、三次方程4种产蛋曲线模型拟合京海黄鸡的生长曲线和产蛋率曲线,并对拟合结果加以比较分析,结果表明,Compertz模型能更好地拟合京海黄鸡的生长曲线(R2=0.9994),杨宁模型最适合应用于京海黄鸡的产蛋曲线拟合(R2=0.976)。
To explore the growth and development of Jinghai yellow chicken and rationally utilize the breed resource,wc randomly selected 300 hens of Jinghai yellow chicken as materials. BW of 0 to 35 weeks of age and laying rate of 19 to 66 weeks of age were measured. Three growth curve models (Logistie,Bertalanffy,Compertz)and four types of egg production curve models (Wood,Yang Ning,Compartment,three equation)were used to fit the growth curve and egg production curve of Jinghai yellow chicken. Comparative analysis showed that Compertz model could better fit the growth curve of Jinghai yellow chicken (R^2=0.9994),Yang Ning model was most suitable to fit egg production curve of Jinghai yellow chicken (R^2=0.976).
