【摘要】 本研究运用三种非线性生长模型即Logistic、Gompertz和Von Bertalanffy模型对0～22周龄闽清毛脚鸡体重生长情况进行曲线拟合和分析。经研究发现，三种模型均能较好地拟合闽清毛脚鸡生长曲线，Gompertz模型拟合效果最优（R2≥0.999）。闽清毛脚鸡公鸡、母鸡Gompertz曲线方程分别为y=2650.863e-4.472e-0.157t、y=1892.757e-4.551e-0.175t。公鸡、母鸡的拐点体重分别为975.20 g、693.31 g，拐点周龄分别为9.54周、8.66周。更多还原

【Abstract】 Three nonlinear growth models, namely Logistic, Gompertz and Von Bertalanffy were used to curve fit and analyze the weight growth of Minqing Maojiao chicken at 0-22 weeks. It was found that all three models could well fit the growth curve of Minqing Maojiao chicken, and Gompertz model had the best fitting effect(R2≥0.999). Gompertz curve equations of cock and hen in Minqing Maojiao chicken are respectively y=2650.863e-4.472e-0.157tand y=1892.757e-4.551e-0.175t.The inflexion weights of cock and hen are 975.20 g and 693.31 g, respectively, and the inflexion weeks are 9.54 weeks and 8.66 weeks, respectively.更多还原
