In order to use mango (Mangifera indica L.) variety Ubá industrial residues, the bromatological composition was determined in the total residues (peels and seeds) and in the kernel seeds. Also was determined physical-chemical characteristics and fatty acids profile of kernel seeds. The effect of inclusion (0; 2.5; 5; 7.5; and 10% of the diet) of total residue or mango residue meal (MRM) was evaluated in the performance and blood biochemical parameters of broiler chicks from one to 42 days of age. Also it was determined the concentration of total phenols in all rations used and in the total residue. Dry matter (DM), crude protein (CP), neutral (NDF) and acid (ADF) detergent fibers, crude fiber (CF), kernel seeds lignin (KSL), ether extract (EE), ash (A), calcium (Ca) and phosphorus (P) and total carbohydrates (TC) were determined. The bromatological composition of kernel seeds and the total residue meals were, respectively: DM 88.36 and 92.23%; CP 4.39 and 3.87%; NDF 29.65 and 37.25%; ADF 2.20 and 21.84%; CF 1.90 and 14.60%; KSL 0.72%; EE 12.18 and 4.36%; A 1.81 and 2.08%; Ca 0.10 and 0.18%; P 0.05 and 0.11%; TC 69.98 and 81.92%. Total phenol compounds concentration varied form 0.0728 to 0.48g/100g in the initial rations, from 0.0917 to 0.665g/100g in the final rations and 5.8g/100g of total residue. 600 broiler chicks, one day old, male, Ross, were used for the biological assay. They were distributed in five treatments with six replicates of 20 animals each. Treatments were corn soybean meal rations with a total residue inclusion of 0; 2.5; 5; 7.5; and 10% of ration. Feed consumption (FC), weight gain (WG), feed/gain ration (F/G), viability and production factor (PF) were determined. FC was not affected (P>0.05) by dietary treatments. WG was not influenced (P>0.05) by the inclusion up top 7.5% of MRM. But F/G and PF were worst at the 7.5 and 10% inclusion level (P<0.05). In conclusion up to 5% of MRM did not affect the broiler performance. Creatinin (C), albumin (AB), total proteins (TP), total cholesterol (TC), HDL, VLDL, LDL and triglycerides (TAG) serum broilers concentrations were determined in chicks at 14, 28 and 42 days of age. No effects were (P>0.05) observed in the broiler serum C, TP, TC, HDL, VLDL, TAG concentrations at 14 days of age. Serum AB levels increased with the MRM inclusion up to 10% (P<0.0%). Serum LDL levels were lower (P<0.05) in animals fed 10 % MRM inclusion in relation to those fed the control diets. No effects were (P>0.05) observed in the broiler serum C, AB, TC and HDL concentrations at 28 days of age. MRM at only 7.5% did reduced (P<0.05) the broiler serum TAG concentrations. Serum TP concentrations were lower in chicks fed 10 % MRM. MRM did reduced the levels of serum VLDL and LDL, but only at 7.5% was significant (P<0.05). At 42 days of age serum C concentrations were lower (P<0.05) in chicks fed rations with MRM. No effects were (P>0.05) observed in the broiler serum TC, HDL and TP at 42 days of age. Serum AB concentrations were higher and TAG and VLDL levels were lower in chicks fed 10 % MRM (P<0.05).
