Corn types with different nutritional profiles, extruded or not, on piglets (6 to 15 kg) feeding

Abstract: -Two experiments were carried out to determine the nutritional value and verify piglets' performance in the nursery phase fed with diets containing common corn (CC), extruded common corn (ECC), high-lysine corn (HLC), extruded high-lysine corn (EHLC), high-oil corn (HOC) and extruded high-oil corn (EHOC). In the total digestibility trial 14 barrows averaging 6.49 ± 0.16 kg initial body weight were allotted in metabolism cages, distributed in a randomized design with seven diets, six replicates, and one piglet … Show more

“…In addition, extrusion could increase the susceptibility of starch to enzyme degradation (Amornthewaphat et al, 2005;de Oliveira et al, 2011) and the proportion of rapidly digestible starch (Sun et al, 2006), and, as was expected in this study, the DE and ME concentrations in extruded and dehulled-extruded diets and extruded and dehulled-extruded corn were greater compared with raw corn diet and raw corn. This finding is in agreement with a previous report that DE and ME concentrations in extruded corn increased slightly compared with non-extruded corn (Herkelman et al, 1990;Menoyo et al, 2011).…”

“…Não houve diferença entre o CDEE (P>0,40) das diferentes rações como também não houve efeito de acidificante (p>0,50) ou interação entre acidificante e dieta (P>0,07). Oliveira et al (15) também não verificaram diferenças na utilização de milho extrusado em relação ao comum em dietas para leitões na fase inicial. No estudo de Mroz et al (12) , não se verificaram diferenças significativas na digestibilidade aparente do EE em relação às dietas com diferentes capacidades tamponantes, apenas se evidenciou diferença (p<0,05) entre dietas quando houve a inclusão de tapioca (76,6%), casca de soja (74,4%) e polpa de beterraba (60,9%).…”

“…O CDRM médio da dieta convencional apresentou um valor maior em relação à alternativa (P<0,001). Da mesma maneira como nas variáveis da fibra, a comparação com outros resultados apresenta o mesmo problema, já que a maioria dos estudos de tratamento térmico de grãos (6,8,15,20) não avaliou a digestibilidade do resíduo mineral. Porém, já foi supracitado que a dieta alternativa apresentou valores de fibra insolúvel (FDN, FDA e FB) consideravelmente superiores aos da dieta convencional pela inclusão principalmente de soja integral.…”
