The objective this work was to evaluate the technical and economic viability of the substitution level of soybean meal by babassu meal in rations to broiler from 22 to 42 days old. It was used 80 male broiler chicks at one day of age, distributed into complete random designs with four treatments (0, 10, 20 e 30% substituition of soybean meal by babassu meal) and five repetitions of four broilers each. Were evaluated the performance (weight dain, feed intake and feed conversion), carcass and cuts, organ biometry, feed cost per kilogram body weight and gross margin. To verify the relationship of cost of replacing soybean meal with pie babassu, inequalities were established. The substitution level of soybean meal by babassu meal had no influence (P>0,05) any of the performance characteristics, wich showed the technical viability of substituting up to 30%. Similarly, there was no affect on carcass yield, cuts weight and organ biometry. The cust less with feed per kg for chicken produced and the higher gross margin were obtained from chickens fed diets with 0% babassu meal. The increased of substitution level soybean meal by babassu meal in ration for broilers from 22 to 42 days old proved unviable economically, however, the inequalities produced can be useful in practical situations.
