摘要
应用VonBertalanffy、Gompertz、logistic、幂函数非线性生长模型对河南大尾寒羊的生长进行了拟合,Gom-pertz和logistic方程能很好地反映河南大尾寒羊的生长特点。本品种具有较好的早熟性;粗放的饲养管理可导致羔羊断奶后体增重急剧减慢;利用回归方程计算的母羊适宜初配日龄为211￣240d。
To study the body weight growth characteristics of Henan fat-tailed sheep, the body weight growth characteristics were fitted by four non-linear fitted models（Von Bertalanffy, Gompertz, logistic, power function） according to the actually observed numerical value. Analyzing and comparing found that Gompertz and logistic fitting-curve have a good fitting of precision with the growth characteristics of Henan fat-tailed sheep. The extensive feeding and management could lead to low weight gain after weaning. The suitable breeding age is 211-240 days according to regression equation.
