Abstract: The objective was to study the growth and development rules of Wenchang chicken.Three nonlinear curves of Logistic, Gompertz and Bertallanffy model were used to fit the growth model in Wenchang chicken of both sex. The results indicated that the growth curves were appropriately fitted with three models, but the Gompertz model had the best effect on fitting with the growth curves. The Wenchang cock and hen grew approximately consistent before the age of 4 weeks, but cock grew faster than hen after the age of 4 weeks. It is feasible to analyze and fit the growth curve of the Wenchang chicken using the three models.
