Popis: The experiment was carried out to evaluate performance, plasma variables, carcass traits and meat quality of growing-finishing pigs fed on diets with increasing levels of neutralized semi-purified glycerin (NSPG). Eighty growing pig (30.31 ± 0.47 to 60.41 ± 0.87 kg) and 80 finishing pigs (60.45 ± 0.46 to 90.99 ± 0.83 kg) were enrolled. Pigs were allotted in a randomized block design with four inclusion levels of NSPG (3.5, 7.0, 10.5 and 14%), mainly substituted the corn in diets. The experiment included 16 replicates and one pig per pen. Additionally, there was a control diet (0% NSPG). At the end of the finishing phase, all pigs were slaughtered to evaluate quantitative carcass traits and meat quality. The regression analysis showed no effect (p > 0.05) of NSPG on growth performance, backfat thickness and loin depth in the growing and finishing phases. As to plasma variables, cholesterol and triglycerides increased linearly only in the finishing phase. A linear increase was obtained in quantitative carcass traits (p
