Evaluation of thermal comfort and performance of broiler chickens under different housing systems

摘要

This research was conducted to evaluate three housing systems for broiler chicken production, aiming to characterize thermal environment and animal performance. The experiment was conducted over 42 days, developed in production modules, divided in 15 boxes with 10 birds per box, and submitted to three housing systems: semi-confined with 3 m2 per broiler of paddock area (SC 3), semi-confined with 6 m2 per broiler of paddock area (SC 6) and total confinement (CONF). The experimental design was completely randomized (CRD), in split plots, with the means compared through the Tu
