Spatial characterization of thermoacoustic and luminance environment in commercial broiler chicken house

The goal of this study was to evaluate and map the thermo-acoustic and the luminance variables inside of a commercial broiler chicken house equipped with conventional ventilation and misting system. Hybro breed broiler chickens were lodged in three regions (refuse, female and male), at a density of approximately 20 birds m-2. The productive environment was evaluated by the black-globe humidity index, relative humidity, air velocity, noise level and luminance. Spatial distribution maps of these variables were generated inside the broiler house using the kriging method. Based on the results, it was concluded that, in general, broiler chickens were subjected to inadequate environmental conditions during the hottest period of the day; however, the exploration potential for using evaporative cooling systems was verified. The spatial profile of the variables related to the productive environment provide for the attainment of more detailed information about the studied system.
