摘　　要：对京白后备鸡的体重和日喂料量进行了测量,建立了体重与平均日喂料量间的回归方程,采用"三和法"拟合了两个生长模型。分析结果表明:体重与平均日喂料量间的回归方程高度显著(P<0.01);Logistic模型和Gompertz模型拟合度均较高(R2分别为0.9871和0.9982);综合分析认为,Gompertz模型为最佳生长模型。The body weight and average quantity of everyday feed on the JingBai reserve chicken is measured. Regression equation is established on the average deal of everyday feed and the weight. The two growth model is established adoption ＂method of Three total＂. Analysis result shows： The regression equation is outstanding highly on the average deal of everyday feed and the weight（P〈0.01 ）. The Logistic model and the Gompertz model are very appropriate （R2 distinguishes is 0.9871 and 0.9982）. Synthesize analysis thinks, the Gompertz model is best growth model.
