RESUMO

The study of female broiler breeders is of great importance for the country as broiler production is the third largest export item, and Brazil is the world second largest producer. The study of female breeder behavior is of scientific interest as it searches of specific pattern that may determine health and welfare in those birds. Production housing needs to provide inside environmental conditions that reaches bird s thermal comfort. This research has as objective the implementation of statistical and methodology analysis tools that may contribute to develop a system of electronic behavior monitoring. The experiment was developed with data collected under controlled environmental conditions, using birds from one genetic, and submitted to three distinct levels of ambient temperature, feed energy and age. Data were organized and processes using the software Minitab@ and SAS@. The descriptive, and exploratory analysis were applied, and afterwards the modeling - using the Generalized Estimate Equation. This research allowed the development of simulation statistical models for predicting female broiler breeders behavior, that may permit the building of an expert system for controlling production housing environment, as well as an indicative of welfare
