Impacto de características zootécnicas e de manejo no desempenho ponderal em um programa de bonificação de bovinos de corte

Abstract

This study aims to develop regression models, which can infer what are the variables that partly explain the weight and gain bonus obtained of the sale of cattle to slaughterhouses. So that these models help the farmers in the most efficient management of your business. Thus allowing an increase in the financial gain from them. And to verify the relationship between qualitative and quantitative factors of animals; identify the relative importance of the model variables and see how variability in the variables interfere in the results for the proposed models. Thus, it was used as a method of Multiple Linear Regression analysis, the method of Ordinary Least Squares(OLS). Through these models can be seen that variables such as birth time, weaning, weaning weight, age at slaughter and ADG of animals, influence on farm weight variables and bonus of animals in carcass quality program. Thus being able to prescriptive models in this study serve as a support tool to decision making for the rancher to estimate the expected results.
