This experiment was conducted to study the effect of the inclusion of a commercial enzyme complex (alpha-amylase, xylanase and proteases) especific for corn and soybean meal based diets, on laying hens performance. One hundred and twenty eight Hy-line White Leghorns hens with 68 weeks of age, in the 2nd cycle of production were assigned to a completely randomized block design with four replications of four birds per block, totalizing 32 birds per treatment. Two isonitrogenous diets with different levels of […]
