Abstract :In this study, 11 different growth curve models (Logistic, Gompertz, McNally, Schnute, Richards, Bertalanffy, Cubic, Cubic Piecewise, Wilmink, Wood, and Log-Logistic) were compared using live weight data of Japanese quails (Coturnix japonica). The predictive performance of the models was evaluated using statistical metrics such as mean square error, corrected coefficient of determination, accuracy and bias factors, Durbin-Watson statistics, Akaike information criterion, corrected Akaike information criterion, and Bayesian information criterion. The analyses determined that the Logistic model best represented the live weight data. The Logistic model provided advantages in terms of high fit, low error, and parametric simplicity. The results demonstrate that the Logistic model can be used in practical breeding applications in modeling the growth processes of Japanese quails (Coturnix japonica). Application of extended modeling approaches with different genotypes and individual data is recommended in future studies.
