To evaluate the effect of two exogenous enzymatic complex (EEC) in diets with soybean meal with different protein solubility on the performance of broilers, 990 Cobb chickens from 8 to 42 days were assigned in a completely randomly design with factorial arrangement 3x2, to diets with soybean meal with 73, 80 and 86% of KOH solubility, and the on top addition (Soy73E, Soy80E and Soy86E) or not (Soy73, Soy80 and Soy86) of a proteolytic (Allzyme VegPro®) and fibrolytic (Allzyme SSF®) EEC. The EEC did not affect (P>0.05) live weight variation (58.9 ± 1.2 g/anim/d), feed conversion (1.95 ± 0.04), viscosity (1.35 ± 0.07 cps) neither intestinal pH (6.5 ± 0.1), increasing the intake on Soy 86 in 3.5 and 2.8% for finishing and total cycle. EEC increased the crypts depth (P=0.052) on 7.1%, and intestinal lesions were lower on Soy73. The EEC addition increased the feed intake when soybean meal had the lower thermal processing, and increased the crypts depth in intestinal villi, without variations in live weight, feed conversion, pH neither intestinal viscosity.
