To evaluate the effect of sunflower meal (SM) and two enzyme complexes (EC) on the performance of finishing broilers, 720 broilers were distributed through a completely randomized design 2 x 3 factorial arrangement, two levels with inclusion sunflower meal (SM); 0 and 3%; including three levels of EC; without EC (NEC), with EC A; (with activity of proteases and cellulases; ECA) and EC B enzymes, with activity the  b-glucanase and xylanase enzymes; CEB, with six replicates of 20 broilers each. The CE factor affected by adding the CEB, obtaining feed conversion (P=0.032) 1.555, european efficiency index (P=0.007) of 377.13, carcass yield (P=0.012) of 76.69%, breast yield (P=0.044) of 24.86%. For the interaction of factors was obtained a feed intake (P=0.005) of 2596.90 g (3%SM+NEC), feed conversion (P=0.0009) of 1,513 (0%SM+CEA), similar index european Efficiency (P = 0.0011) of 399.86 (0% SM + CEA) and 379.98 (3%SM+CEB), the diet 3% SM + ECB with carcass yield (P=0.0024) of 77.14% and breast yield (P=0.044) of 25.72%. These results demonstrate that adding 3% HG do not affect production performance and the addition of both EC generate positive results, more efficiently ECB, obtaining a performance viable economically for broilers feeding.
