Various Curve -fitting and Comparative Analysis of Accumulative Egg Production of Langshan Chicken
摘要
Abstract
The curve - fitting analysis of the accumulative egg production of Langshan chicken was conducted by using 3 kinds of widely - used nonlinear growth models: Logistic, Gompertz and Bertallanffy model. The results showed that these 3 kinds of models all could well simulate the accumulative egg production, and their fitting degree (R2) all reached above 0. 99, but the fitting effect of Bertallanffy model was the best, and this model got more accurate inflexion day - age and inflexion egg production. Further study on the fitting parameters of Bertallanffy model indicated that the inflexion egg production of Langshan chicken was 66. 142 eggs, and its inflexion day -age was-275.412 days. Therefore, Bertallanffy model could be used to estimate and forecast the accumulative egg production of Langshan chicken in the actual production.关键词
