In broiler poultry, the formulation of balanced diets at optimal costs is becoming more challenging every day, due to the increase in the price of inputs, as well as their altered availability, have made diets more expensive. The objective of our study was to evaluate the effect of the inclusion of xylanase in broiler diets of lower caloric value with less energy inputs on productive performance and profitability. 120 1-day-old baby chickens of the cobb500 line were used, which were distributed in three treatments, DB: Base diet (Without xylanase), DB80: Base diet with xylanase with less than 80 kcal/kg and DB120: Base diet with xylanase minus 120 kcal/kg with five replicates. The work was carried out during the months of June and July 2022 (1 to 42 days old); at La Soledad farm; located at km 592 Chicama; province of Ascope department of Liberty. The results were analyzed through the analysis of variance and did not show a statistical difference in any of the variables studied; however, xylanase treatments with hypocaloric diets of DB80kcal/kg and DB120 kcal/kg showed higher final weight and greater weight gain (3.11kg; 3.17kg and 72.65g; 73.96g respectively), in relation to the base diet. without xylanase (DB: 3.07kg and 71.71g). Regarding feed consumption, the results were favorable for the treatments with xylanase DB80: 132.38g and DB120: 132.81g, compared to the treatment without xylanase DB: 128.98g. Feed conversion was similar for all treatments (DB:1.80, D80:1.82, DB120:1.80). Obtaining greater profitability in the treatments with xylanase, with 55.15 and 58.98%; compared to 52.74% of the treatment without xylanase. Therefore, it is concluded that the inclusion of xylanase in diets with lower energy value generates the necessary energy intake, which does not negatively affect productive performance and increases profitability. Finally, it is recommended to evaluate the effect of xylanase in diets with less energy inputs on the microbiota and intestinal integrity. Keywords:
