This research aimed to carry out a bioclimatic study of Sergipe state to poultry farming, as a way to define the limits of acceptability of the species to the prevailing environmental conditions in coastal, agreste and semi arid regions of the state. For this survey it was conducted a history of the monthly mean values of temperature and relative humidity of the air and the calculation of the monthly index of temperature and humidity (ITU) of the three regions of the state of Sergipe. It was found that despite its special climate, coastal, agreste and semi arid region of Sergipe present the best thermal comfort conditions for the poultry industry and posture only during the months from June to September. In the dry season, no region presents thermal comfort conditions for the poultry activity. Only in the rainy season the region has rugged comfort conditions for the poultry industry. For laying poultry only the coastal region not provides thermal comfort.
