ABSTRACT – The present work was conducted to evaluate the effect of constant thermal environment on the performance and physiological traits of barrows from 30 to 60 kg LW. A total of 100 animals were allotted to a randomized block design, with five treatments (3100, 3250, 3400, 3550 and 3700 kcal of DE/kg of diet), five replicates and two animals per experimental unit. Weight gain, intakes of diet, protein and energy and feed:gain ratio and the efficiencies of protein and […]

This experiment was carried out to evaluate the metabolizable energy (ME) (2850, 2921, 3000, 3075 e 3150 kcal/kg) levels for male broilers from 1 to 21 days of age, maintained in thermoneutralenvironment. Four hundred and fifty chicks, male, with average initial 44±0.2 g LW, were allotted to a completely randomized experimental design with five treatments, nine replicates and ten animals per experimental unit. The ME level of the diet affected the average weight gain and the ME intake, which increased, […]
