Resumen : There measured of the effect of two environmental conditions (hot and fresh) on the biometric variables in chickens broilers separated by sex and corporal condition (CC). The treatments followed a design factorial of 2x2x2 two artificial conditions of environment, hot (C=TA > 30 °C) and fresh air (F=TA prom, 25 °C) with two corporal conditions lewd (L) and weighed (W), separated by sex (M=male, H=female). There took 1 chicken of every cage to realize measures of life weight (LW) of legs, head, total entrails, heart, bursa, liver, kidney, lung, carcass; with a scale Ohaus of precision 0,01g. the chickens in hot climate had minor LW and consumption of food and major consumption of water that the chickens in fresh condition The proportion of the organs decided with regard to the LW. There were significant differences in the measurements later to the differentiation of environment in only five variables; the heart presented irregular proportion, where CMP and FMP, were possessing major proportion with 0,45 % ± 0,16; the hot environment presented minor proportion of bursa with an average of 0,096 % ; with regard to the chickens of the fresh environment. There are important changes in the organs heart, bursa, spleen and legs concerning the age, which guard relation with the caloric stress, though the environment, the sex and the CC, they are not determinant factors in the proportions of the organs.
