Mixed Models in Nonlinear Regression for Description of the Growth of Nelore Cattle
Body weight records were used to characterize the growth curve of Nelore cattle.Body weight was regressed as a function of age, for both sexes, by using nonlinear models through the functions of Brody, Gompertz, Logistic, Richards, Meloun 1, Von Bertalanffy, and Von Bertalanffy.The quality of the model arrangements was evaluated by employing Akaike
