This study was carried out with the aim of evaluating the effects of the inclusion of the wheat bran (WB) and the addition of an enzymatic complex (EC), amylase, protease and celullase contained, on the performance of semi-heavily pullets from 14 weeks of age and its residual effect on egg-production phase. 288 pullets were used, distributed in a completely randomized design in a factorial arrangment 4X2, being the following levels of WB in the ration: 0 (control), 10, 20 and 30% X 0 or 50g of a EC/100 kg of diet, resulting in eight treatments, with six replicates of six birds. The EC contained the enzymes amylase, protease and celullase. In the growth phase, FI, WG, FC and LW showed better for the birds that received the diets without FT. The addition of the EC decreased the consumption in the diets with 0 and 30% of WB. During the production phase, the use EC in the level 0% of WB increased LW of the birds, but it reduced in the level 30% of WB. The production of eggs fell in the level of 20% of WB when the diet was supllementing with EC. The feed conversion in the level of 10% of WB was similar to the control. Quadratic effect of the level of WB was observed on the feed egg-mass conversion, that was better with 8,01%. Therefore, it is recommended up to 8.01% of inclusion of the wheat bran in the ration of semi-heavily pullets from 14 to 19 weeks of age.
