The objective of the research was to evaluate the effect of adding a energetic substrate on the productive behavior and economic profitability in diets of laying hens from week 40 to 47 of production. 672 Hy Line Brown hens were used, housed in experimental units with 28 birds each one (four cages of seven birds each one), distributed under a completely randomized design with four treatments (0%,0.1%,0.2% y 0.3% energetic substrate adition) and six repetitions. The diets were formulated to meet the nutritional requirements of the hens in this stage, the results were analyzed through the analysis of regression. The posture percentage, feed conversion, egg mass and weight showed significant difference (P<0.0001); the best results were obtained with the 0.2% energetic substrate addition. The economic profitability was major in the diet with 0.2% energetic substrate addition. It is concluded that the addition of energetic substrate in laying hens’ diets improve the productive behavior and increases the economic profitability.
