摘要：Thermal comfort is essential to animal production directly influencing feed conversion and increase in production. The experiment was conducted at the Laboratory of Rural Buildings and Ambience-seals, the Federal University of Campina Grande. Is conducted in two stages lasting 32 days each. 768 European quail (Cortunix cortunix cortunix) were used. We used 2 battery cage\s, each containing 6 cages and they split into two boxes, totaling 12 boxes per battery. Environmental temperatures (25 °C and 29 °C) to population density (70 birds / m2 and 90 birds / m2) in the two temperature ranges were simulated, and the relative humidity equal for both the stages, around 60%. Performance in weight gain under such circumstances, where the difference in population density no significant interference occurred, however, a difference of 20 g in average weight gain per animal was analyzed as the lower temperature.
