The concern about comfort levels in poultry production is increased during the recent years, gaining more importance due to complexity with which the production factors are correlated. A great number of climatic factors affect the environment inside the animal housing and to know it's influence on final production is determinent for better understanding of environmental phenomena. The maintenance of thermal comfort inside the poultry houses is one of the problems faced by the broiler producers. The birds respond in different ways depending on the conditions of internal temperature and relative humidity. The ingestion of ration and water is also influenced by the same conditions, reason for which, in this study, an evalution of behavior of broilers submitted to different combinations of temperature and relative humidity under climatizied conditions was monitored by video cameras, permitting individual (animal) electronic monitoring (camera and video) of birds with regard to broiler's ingestive behavior. The results showed that the water ingestion was higher with increased in temperature and age, while the food ingestion was lesser when the temperature and age increased.
