Fitting and Analysis of Growth Curve for Jining Grey Goats
摘要
Abstract
To study the growth and development regularities of Jining grey goat, the weights of 0 ～ 18-month-old Jining grey goat with different sex were measured in the experiment. Their growth curve were fitted by three nonlinear growth models including Von Bertalanffy, Gompertz and Logistic. The results showed that all the three models could better fit the growth of Jining grey goat (R2 > 0. 970). The fitting results of Von Bertalanffy model was much closer to the actual values, so it had the best fitting effect. Through further study the fitting parameters and estimated values of Von Bertalanffy model and the actual values, we concluded that the inflection growth point of ram was at the age of 3. 873 months and the corresponding body weight was 10. 379 kg, while that of ewe was at the age of 3. 635 months and the body weight was 9. 387 kg. The inflection point weight of rams was higher than that of ewes, and the inflexion point age of rams was larger than that of ewes in the three models.关键词
