RESUMO

The objective of the present work do the bioclimatic profile of the state of Sergipe to poultry farming, as a way to define the limits of acceptability of the species to environmental conditions prevailing in the microregions of the state. For this reason a survey history of the last 61 years, the monthly average values of temperature and relative humidity of the air. From climatic data was done the calculation of monthly index of temperature and humidity (ITU) for all microregions of Sergipe state in order to diagnose, the months with situations of comfort and thermal discomfort for the creation of birds. The microregions of Sergipe state presented monthly average values of temperature between 24 and 25 C, and is therefore within the zone of thermal comfort for the creation of laying hens and below the zone of thermal comfort for the creation of broilers with age from 17 to 45 days. The average values of relative humidity of the air, for all the microregions of Sergipe, remained outside of the patterns of thermal comfort for poultry, with values higher than 82 %. All microregions of Sergipe state, during the months of July and August presented the best thermal comfort conditions for the poultry and egg laying, with average values of ITU below 74. During the dry period, the three regions of the state did not provide thermal comfort conditions for the poultry business, with average values of ITU between 75 and 76. During the rainy period only the foothills region shows favorable conditions for the poultry, with a mean value of ITU 73, for the poultry of posture only the coastal region was not thermal comfort conditions, with an average value of ITU 75.
