Modelo de Von Bertalanffy e aplicações.

Abstract

At every moment, Mathematics becomes more present and necessary in our daily lives. In this work, a study on Differential Equations was carried out, emphatically on the Von Bertalanffy’s model. This research aims to find an equation that more effectively describes the experimental

data of this study, referring to the weight of free range chickens raised outdoors (in non- confinement). The methodology consists of the experimental part, of data collection (chicken’s

weight), and the theoretical part, in which the generalized Von Bertalanffy’s model was used to describe the weight-age experimental data, calculate the values of the parameters existing in the model. In this sense, it was possible to discuss the best time to slaughter the bird so that the rural producer can reduce expenses and increase their profits. Thus, with this work, it was possible to evaluate the bird’s growth process in terms of its weight and thus estimate how far it is profitable to keep the chicken alive.
