Abstract

GONCALVES, Liliane Maria Piano et al. Semi purified glycerins in growing and finishing pigs feeding (30-90 kg). Rev. bras. saúde prod. anim. [online]. 2014, vol.15, n.1, pp.221-236. ISSN 1519-9940.  https://doi.org/10.1590/S1519-99402014000100018.

Two experiments were carried out to determine the nutritional value and to evaluate the performance and carcass traits in the growing-finishing pigs fed on two types of semipurified glycerin, which were made from vegetable oil (SPGV) and mixed of animal + vegetable oil (SPGM). In the digestibility trial (experiment I) 32 crossbreed barrows were used with initial body weight of 45.08 ± 4.11kg. It were used three levels of inclusion (6, 12 e 18%) of semipurified glycerin (SPGV and SPGM) in the basal diet. The metabolizable energy (ME) value of glycerin were estimated by regression of ME (kcal/kg) intake associated with glycerin vs. glycerin intake (kg). The values of ME (kcal/kg) obtained were: 2,731 for SPGV and 2,210 for SPGM. In experiment II, 72 pigs (30.08 ± 1.65 to 60.58 ± 3.57) in growing and (60.83 ± 2.63 to 93.79 ± 5.72) in finishing phase, were allotted in a completely randomized design in a 2 x 4 + 1 factorial scheme, with two types of semipurified glycerin (SPGV and SPGA), four inclusion levels (4; 8; 12 and 16%), eight experimental unit and a control diet containing no glycerin (0%). All pigs were slaughtered to evaluate the carcass traits. The performance results suggest that it is feasible to use up to 16% of both semipurified glycerins on growing and finishing pigs feeding, without impairing performance and carcass traits.
