Resumo

Two experiments were carried out aiming to determine the nutritional value and to evaluate performance, carcass traits and economic feasibility of growing-finishing pigs fed on two types of crude glycerine (CG) which were made from vegetable oil (CGS), and mixed of animal fat + soybean oil (CGA). In Experiment I, a digestibility assay were carried out using 32 (24 test diet and 8 basal diet) cross breed pig (45.08 ± 4.11 kg). The experimental unit consisted of one pig, with a total of four experimental units per diet. Glycerine levels used in the digestibility assay were 6, 12, and 18% of the basal diet (corn + soybean meal based). The values (as-fed-basis) of DE and ME (kcal/kg) obtained were: CGS= 5,040 and 4,481; CGA= 5,234 and 4,707, respectively. In the Experiment II, 63 pigs, were allotted in a completely randomized design in 2 x 4 factorial scheme, with two types of crude glycerine (CGS and CGA) and four inclusion levels (3, 6, 9, and 12%). Additionally, it was formulated a control diet containg no glycerine (0%). There was no interaction (P?0.05) among levels of CG and types of glycerine sources, and the regression analysis indicates no effects (P?0.05) of crude glycerine inclusion on performance and carcass traits (backfat thickness and loin depth). The results suggest that it is feasible to use up to 12% of both crude glycerine (made from soybean oil and mixed) on growing-finishing pigs diet, without impairing performance and carcass traits, besides providing a reduction of about 11% on feeding cost.
