This research was conducted in the facilities of the Poultry Nutrition and Feed Research Laboratory at “Universidad Nacional Agraria La Molina”. The objective of this research was to evaluate the effect of exogenous xylanase, amylase and protease on performance, carcass parameters and intestinal morphometry. 75 Cobb 500 male broilers housed in galvanized cages with heaters were randomly distributed into three treatments divided in five replicates with five birds each one. The treatments were the following: control treatment (T1), negative control treatment deficient in 100 Kcal/kg of feed and 3 % of protein and amino acids (T2) and negative control with addition of the enzymes (T3). Water and feed were supplied ad libitum. Body weight, weight gain, feed intake and feed conversion ratio were registered. At the end of the 28 days experiment, carcass weight and intestinal samples were taken in order to determine carcass yield, breast yield and intestinal morphometry. Animals fed with the starter diets showed significant difference (P<0.05) related to feed conversion ratio in favor of T1, nevertheless, there was not significant difference (P>0.05) between T2 and T3. As to body weight and weight gain during initial stage, there was not significant difference (P>0.05) between T2 and T3, nonetheless, there was significant difference between T1 and T3, probably due to nutrient reduction and feed intake reduction tendency when enzymatic complex was added. During growing stage and total stage, there was no significant difference (P>0.05) among the treatments regarding to body weight, weight gain, feed intake, feed conversion ratio, carcass yield, breast yield or intestinal morphometry. At the end of the experiment, the xylanase, amylase and protease treatment obtained a better economic return per bird in 0.69% regarding to the control.
