Abstract :This study was conducted to determine the adaptation of the individual growth curves of Japanese quails to both female and male quail data modeled by using Richard, Logistic, Gompertz, Von Bertalanffy, Cubic Spline and Quadratic Spline models. In the study, 810 quail data consist of 298 females and 512 males were used as material. For six different models, Mean Square Error insert ignore into journalissuearticles values(MSE);, Durbin-Watson autocorrelation test insert ignore into journalissuearticles values(DW);, Akaike Information Criteria insert ignore into journalissuearticles values(AIC);, Adjusted Determination Coefficient insert ignore into journalissuearticles values(adj. R 2 ); values were compared for both female and male quails. In addition model predictions of growth curve parameters were shown. As a result of this study for individual growth curve models in Japanese quails, MSE= 92.50 ± 17.69, adj.R 2 =0.986 ± 0.001, AIC= |-19.21| ± 0.15 and DW= 2.21 ± 0.01 for female quails MSE= 35,391 ± 9.07, adj.R 2 =0.997 ± 0.033, AIC= |-35.04| ± 0.29 and DW= 2.09 ± 0.91 for male quail. It was found the cubic Spline model, which was the best model for both female and male quails.
