|Title:||Bioclimatic Patterns With In Tom Turkey Housing|
De Moura D.J.
|Abstract:||The turkey productive chain has become competith'e and highly speciahzed in the recent years. Desiring to achieve thermal and environmental equilibrium, a joint action of variables including the concentration of CO2 environment temperature and air relative humidity (RH) was evaluated. This study aimed to map the behavior of these variables along the poultry house interior in order to analyze the magnitude and homogeneity facing two different ventilation systems (A1 = poultry house with minimum negative ventilation and A2 = poultry house with minimum positive ventilation). Minimum negative ventilation means that fans on the roof worked to exhaust air, while minimum positive ventilation means that the fans directed the air into the poultry house. In the winter of 2007, two commercial turkey houses of initial production stage were used. The poultry house was located at Francisco Beltrâo city. The data were submitted to an analysis of variance. It was concluded that the minimum positive ventilation system (which injects the air into the house) provided a better themraml environment to the birds: there were similar concentrations of CO2, higher environment temperature (not so much heat loss to the external environment and no need for supplemental heat), and lower internal RH (due to the highest internal temperatures and the highest air movement).|
