The objective of this study was to evaluate the effect of supplying diets containing different levels of the blend: candy industry residue (CIR) + corn gluten feed (CGF) replacing ground corn, on the physicochemical compositions of sheep carcasses in growth of the Santa Inês breed. Thirty six lambs were used, non-castrated, with an average age of six months and initial body weight of 19.43 ± 1.69 kg, distributed in a completely randomized design in the treatments: 1) control, without addition of CIR + CGF; 2) replacement of 33% of corn by CIR + CGF; 3) replacement of 66% of corn by CIR + CGF; and 4) replacement of 100% of corn by CIR + CGF in the diet based on dry matter. The experimental period lasted 63 days. After slaughter, the carcasses were weighed and cooled for 24 hours. Then weighed and divided into two half carcasses. The left half carcass was dissected to obtain the physical and chemical composition of the carcass. The data were evaluated by means of analysis of variance and regression, using SAS 9.4 (P <5%). The replacement of corn by RID + FGM did not influence the physicochemical compositions and tissue relationships of the carcass and meat cuts. Ground maize can be completely replaced by mixing the residue from the candy industry with corn gluten feed (ratio 613: 387 in dry matter) without affecting the carcass physico-chemical compositions.
