RESUMO

This research aimed to evaluate the impact of the combination of bioclimatic variables such as: temperature, wind velocity and relative humidity in turkey production, as well as the efficiency of two minimum ventilation systems (positive and negative) for the initial phase ( 1 . 28 days), and three acclimatization systems (positive ventilation I, positive ventilation II and negative ventilation) for the final turkey growing stage ( 4 . 20 weeks). The turkey housing was placed at Francisco Beltrão country, Paraná state, used in the initial stage of production there were compared the following parameters: CO2 concentration, both ambient temperature and relative humidity, and production index. In the houses located in the country of Uberlândia, Minas Gerais state, used in the final stage of production the following data were compared: CO2 concentration, both ambient temperature and relative humidity, light intensity and production index. It was concluded that air CO2 concentration was below the maximum internationally recommended limits for both stages of growth. The ambient temperatures for both ventilation systems evaluated in the initial phase remained within the thermal comfort zone, and the relative humidity was also whit the recommended limits. For the final growing stage the ambient temperature in both evaluated acclimatization systems were above the recommended for the birds, and the mean air relative humidity results were also within the limits. It was concluded that for the initial and final growing stage the minimum positive ventilation system and the negative tunnel ventilation system respectively provided better thermal environment for the birds. For the final growing stage was not possible to choice the best one between the positive ventilation systems I and II
