| 摘 要： | 利用14头杜洛克公猪1 596条连续日称重记录,进行了Logistic方程和Compertz方程的生长曲线拟合分析。结果表明:两种方程的拟合度(R2)在0.99以上,拐点体重和日龄差别不显著。但综合杜洛克公猪实际成熟体重考虑,用Compertz方程对杜洛克公猪进行生长曲线的拟合效果更好,更接近实际。

| Abstract: | The 1 596 daily body weight records of 14 Duroc boars were used to fit the growth curve,the Logistic and Gompertz function were tested.The results showed that R2 of the two functions were all up to 0.99,the point of the inflection for the body weight and age have no significant difference,and the Gompertz function was better than the Logistic function,as the maturity body weight was considered. |
