Resumo: | The experiment was conducted to determine the effect of feeding three levels of energy (2800, 3000 and 3200 kcal ME/kg) in diets and two stocking densities (10 and 22 birds/m 2) on broilers performance. The experimental design was randomized blocks in a 3 × 2 × 2 factorial arrangement with four replication per treatment. The factors studied were levels of energy in the diet, population density, and sex. The birds were killed at 42 days of age. The data indicate that increasing energy levels in the diets of broilers, 1 to 42 days of age, reduced feed intake, improved feed conversion, and increased the amount of abdominal fat, energy intake, and weight gain without affecting carcass yield. There was no significant effect of diet on the live weight production of broilers produced per area of floorspace or on mortality. The higher values for carcass yield were obtained for birds raised under the higher population density and for males in comparison to females. With the exception of the undesirable elevation in the amount of abdominal fat, the increase in the level of energy in the diets resulted, in general, in an improvement in the performance of the broilers independent of the population density. However, the response to the amount of energy in the diet was similar for both population densities. |
