Abstract: The growth curve of Bian chicken was analyzed and fitted with three kinds of nonlinear models(Logistic, Gompertz, Bertallanffy). The results showed that the growth curves were appropriately fitted with three models. The values of R2 were higher than 0.99, and the Bertallanffy models had the best effect on fitting with the growth curve(the values of R2 in cock and hen were 0.9974 and 0.9984 respectively). It is feasible to analyze and fit the growth curve of the Bian chicken using the three models.
