摘要： 为了研究高邮鸭的早期生长发育规律,本试验运用Gompertz、Logistic和Von Bertalanffy 3种非线性生长模型对高邮鸭1~10周龄生长情况进行了分析和曲线拟合。结果表明,高邮鸭早期生长迅速,3周龄时体重增加最大;3种模型均能较好地拟合高邮鸭早期生长,其中Gompertz曲线模型的拟合度为0.99902,拟合估计值与实际观测值最接近,拟合效果最佳,更适合早期生长发育较快的高邮鸭。

Abstract: In order to study the rules of early growth and development of Gaoyou duck, the nonlinear curves of Gompertz model, Logistic model, Von Bertalanffy model were used to analyze the growth of 1 to 10-week-old Gaoyou duck and fit the growth model. The results showed that Gaoyou ducks grow rapidly early. The gain weight reached the pinnacle at 3 weeks old. The growth curves were appropriately fitted with all three models, but the Gompertz model had the best effect on fitting the growth curve, and the value of R2 was 0.99902, and the estimated values were more similar to the observed values. It was indicated that the Gompertz model was more fit to early growth of Gaoyou duck.

Key words: Gaoyou duck; growth curve; body weight; model; fitting
