This study aimed to evaluate the performance, carcass characteristics and economic viability with the inclusion levels of residue processing of the mango (RPM) in the diet of slow growing broilers. For this, 250 male chicks were used, black carijó line with 1 day old, in a completely randomized design (CRD) with 5 treatments and 5 repetitions of 10 birds each. The treatments consisted of a ration formulated control based on corn and soybean meal and the other containing inclusion of 2, 4, 6 and 8% of RPM . According to the regression analysis increased linearly, only feed conversion, an increase of RPM the inclusion level in the period 1-28 and 1-78 day-old chickens. The RPM the inclusion levels did not affect carcass traits, except the gizzard, which showed higher yield when comparing the diets with levels from 4% of RPM with the control diet. Yet for gizzard, there was a linear increase in revenue in the same elevating RPM levels. The analysis of economic feasibility by comparing the diets containing the RPM with the control diet, there was a significant difference in cost of feed per kilogram of weight gain (CFK), economic efficiency index (EEI) and cost index (CI) only for the diet with 8% of RPM. The inclusion of RPM from 2% provided linear increase in CFK and CI and linear reduction in the EEI. However, one can include up to 8% RPM at the feed slow growing broilers without sacrificing performance and major characteristics of the poultry carcass. However, is economically feasible to use levels up to 6%.
