    Abstract


    The study was conducted to determine the appropriate non-linear function to describe the laying rate curve of fighting chickens raised at Dabaco Chicken Breeding Company. The data collected was the laying rate of two groups including 600 Black fighting and 600 Dark Brown fighting hens from 1st to 26th laying week raised in an intensive farming system. Four mathematical models Logistic, Logistic Curvilinear, Compartmental and Modified Compartmental were used to investigate laying rate curve. The results obtained included mathematical parameters of the curve, weeks of age and peak laying rate, and criteria for the suitability of the models. The Modified Compartmental model with lower values of AIC, BIC, MSE, MAE and MAPE was the most appropriate to describe the laying curve for the Dark Brown fighting hens. The Modified Compartmental model and the Logistic Curvilineear model were appropriate options to describe the laying curves for the Black fighting hens.
