- Abstract
To find out the growth and development regularity, the growth curves of Muchuan black chicken at the age of 0 - 21 weeks were established by Logistic, Bertalanffy and Gompertz models in this study. The results showed that all the three models can well fit the growth curve of Muchuan black chicken with a degree above 0. 988, while the Gompertz model and the Bertalanffy model was the best for hens and cocks, respectively. Finally, the weight of hens and cocks were analyzed according to their corresponding high fitting models. Results showed that the inflexion age of Muchuan black chicken was 6. 8 - 6. 9 weeks old with an inflexion weight of 692. 98 g in hens and 805. 57 gin cocks. In conclusion, it was feasible to establish the growth curve of Muchuan black chicken with Logistic, Bertalanffy and Gompertz model.
