Abstract: ResumoObjetivou-se avaliar a inclusão de glicerina bruta para leitões na fase de creche. No ensaio de desempenho, foram usados 80 animais machos, castrados, com peso inicial de 6,64 ± 0,8 kg. O delineamento foi de blocos ao acaso e os tratamentos consistiram em 0%; 2%; 4% e 6% de glicerina bruta. Houve efeito quadrático para peso final, ganho médio diário e consumo de ração, a máxima inclusão de glicerina bruta foi de 2,77% para maior consumo diário. Para o GMD, o nível de 2,76% de glicerina bruta possibilitou… Show more

“…The ADG and ADFI observed in this study were higher than the estimated expected ADG and ADFI for piglets at a relatively stress-free environment (NRC, 2012), indicating that the nutrient dilution resultant from glycerin inclusion did not impair performance. Other studies also reported no effects on performance in nursery piglets fed diets containing 120 and 140 g kg −1 glycerin (Diaz-Huepa et al, 2015;Gallego et al, 2016), whereas several authors found improved performance results in nursery pigs fed up to 100 g kg −1 crude glycerol (Groesbeck et al, 2008;Zijlstra et al, 2008;Shields et al, 2011;Rocha et al, 2016). The replacement of 100 g kg −1 of lactose with glycerin in diets of weaned piglets resulted in lower DM TTAD and GE TTAM coefficients and higher GE losses in urine and feces; however, piglet performance was not negatively affected, indicating that glycerin may be a viable alternative to replace up to 100 g kg −1 of lactose in diets of weaned piglets.…”
