Evaluation of reflective painting of the roof and artificial ventilation on performance and carcass yield of broilers

This study was developed with the objective of evaluating reflective paint on covering and artificial ventilation on performance of broilers (males and females). A randomized design with a 2 × 2 × 2 factorial arrangement of treatments was used, as follows: 2 external management systems (coverage with and without reflective paint), 2 internal management systems (with and without artificial ventilation) and 2 sexes (male and female), totalizing 8 treatments. A total of 480 1-day old chicks of the Cobb strain were distributed randomly, according to sex, to treatments. Each treatment consisted o...
