摘  要:
为了研究斑嘴鸭的生长发育规律,试验采用Logistic和Gompertz 2种非线性模型对斑嘴鸭体重变化规律进行拟合。结果表明:2种模型均能较好地拟合斑嘴鸭生长规律,但与Logistic相比,Gompertz模型拟合效果更好;斑嘴鸭快速生长区间为9.15~57.27日龄,在33日龄生长速度最快,每天增重15.60 g。

摘  要:
To explore the growth law of Anas poecilorhyncha,two kinds of nonlinear curves of Logistic and Gompertz models were used to fit the change of body weight in the study.The results showed that the two models could fit the growth of Anas poecilorhyncha.However,compared with Logistic,the fitted effect of Gompertz was better.According to Gompertz model,the time interval of rapid growth was 9.15-57.27 days.The time of growth fastest was 33 days,increasing weight was 15.60 g every day.
