摘　　要：本文对麻旺公母鸭体重随日龄增长应用Logistic和Gompertz模型进行生长曲线拟合分析,建立麻旺鸭公、母鸭的拟合曲线方程及求出拐点体重、拐点日龄。结果表明:两种模型均能很好地拟合公、母鸭生长规律,Logistic和Gompertz模型拟合公鸭的拟合度分别为R2=0.983,R2=0.986,母鸭R2=0.989,R2=0.990,两种模型相比,Gompertz拟合效果更好。This paper mawang drake and duke weight increased with age and Applied Logistic and Gompertz model for growth curve fitting analysis,Mawang drake and duck fitting curve equation and find the growth inflexing on body weight and age.The results showed that:two models can well fit the drake and duck growth pattern,Logistic and Gompertz model fit drake of values were R2 = 0.983,R2 = 0.986,duck R2 = 0.989,R2 = 0.990,compared to two models,Gompertz fit better.
