Table 1.
Fixed and mixed nonlinear models for the functions of Brody, Gompertz, Logistic, Morgan-Mercer-Flodin, Richars and Von Bertalanffy.
Table 2.
Number of observations (N) means and standard deviations (SD) for body weight of male and female quails at different ages.
Table 3.
Estimation of parameters obtained in the models that used the functions: Morgan-Mercer-Flodin, Gompertz and Von Bertalanffy, considering asymptotic weight as random at age âtâ.
Fig 1.
Predicted body weight and absolute growth rate (AGR) as a function of age (days) using the Morgan-Mercer-Flodin model for male and female quails, with asymptotic weight parameter being random.
Note: pred_m, and pred_f are the body weights of males and females, respectively. TCA_m, and TCA_f are the absolute growth rates of males and females, respectively.
