Neutral semi-purified glycerin in starting pigs feeding
Glycerin is a major co-product resulting from biodiesel production, and it has been proposed as a highenergy source for use in swine diets. However, it is necessary to determine the nutritional value of neutral semi-purified glycerin (NSPG). In this study two experiments were carried out to determin...

There were ten replicates with two piglets per experimental unit. Additionally, a control diet containing no glycerin (0%) was formulated. The results show it is feasible to use up to 14% NSPG in piglet feed without impairing performance and plasma chemistry. http://www.uel.br/revistas/uel/index.php/semagrarias/editor/submission/16732Biodiesel; Digestibility; Glycerol; Performance |

Glycerin is a major co-product resulting from biodiesel production, and it has been proposed as a highenergy source for use in swine diets. However, it is necessary to determine the nutritional value of neutral semi-purified glycerin (NSPG). In this study two experiments were carried out to determine the nutritional value, evaluated the performance and economic feasibility of starting piglets fed on neutral semi-purified glycerin. A digestibility trial (Experiment I) was conducted using 30 crossbred barrows with an initial average body weight of 42.91±1.58 kg. The glycerin levels used in the digestibility assay were 4, 8, 12 and 16% of the basal diet (corn + soybean meal based).
