摘要: 【目的】研究京红系蛋鸡的生长发育规律,运用科学的数学模型对其分析,比较得出京红系蛋鸡最适生长曲线。【方法】通过选用Logistic 、 Gompertz和Bertalanffy 3种常用模型对育雏、育成阶段540只京红系蛋鸡体重、胫长分别进行生长、发育曲线拟合和分析。【结果】更加适合京红系蛋鸡体重生长曲线的模型是Gompertz模型,其拟合度0.999。其模型模拟的京红系蛋鸡的体重曲线方程为Y=1 731×e-4.067 exp(-0.187 t),其拐点周龄和拐点体重为7.502周龄和637.123 g。并且更加适合京红系蛋鸡胫长发育曲线的模型是Logistic模型,其拟合度0.997。其模型拟合的京红系蛋鸡的胫长曲线方程为Y=101.029/(1+2.098×e-0.271t),其拐点周龄和拐点胫长为3.953周龄和5.051 cm。【结论】Gompertz 模型对 0~17 周龄京红系蛋鸡体重的拟合效果最佳,Logistic模型对0~17周龄京红系蛋鸡胫长的拟合效果最佳。

Abstract: 【Objective】 The growth and development regularity of Jinghong hens was analyzed by scientific mathematical model, and the optimal growth curve of Jinghong hens was compared.【Method】Through the selection of three commonly used models of Logistic, Gompertz and Bertalanffy, the growth and development curve fitting and analysis were carried out for the weight and length of 540 Jinghong hens in the brooding and breeding stages.【Result】The comparison of the three models showed that the model suitable for the weight growth curve of the Jinghong system was the Gompertz model with a fit of 0.999. According to the experimental data, the weight curve equation of the Jinghong hens simulated by the model was Y=1731×e-4.067exp(-0.187t), and the inflection point age and the inflection point weight were 7.502 weeks old and 637.123 g. And the model more suitable for the growth curve of Jinghong hens was the Logistic model, and its fitting degree was 0.997. According to the experimental data, the equation of the length curve of Jinghong hens fitted with the model was Y=101.029/(1+2.098×e-0.271t), and the inflection point age and inflection point length were 3.953 weeks old and 5.051 cm.【Conclusion】 The Gompertz model has the best fitting effect on the body weight of 0-17 weeks old Jinghong laying hens while the Logistic model has the best fitting effect on the length of 0-17 weeks old Jinghong laying hens
