Digestibilidade Da Materia Seca E Parâmetros Da Fermentação in Vitro De Plantas Forrageiras

Abstract: RESUMO:Objetivou-se avaliar a digestibilidade da matéria seca (MS) e os parâmetros da fermentação in vitro de plantas forrageiras in natura e ensiladas no período da seca por meio da técnica de 24 horas de incubação. As plantas forrageiras avaliadas foram Brachiaria brizantha cv. Marandu; Brachiaria humidicola; Panicum maximum cv. Mombaça; Panicum maximum cv. Massai; silagem de milho (Zea mays); silagem de sorgo (Sorghum bicolor L. Moench); cana -de-açúcar (Saccharum officinarum L) picada in natura. Foi utiliz… Show more

“…Geron et al (2014Geron et al ( , 2015 evaluated the DM IVD and fermentative parameters of diets with increasing levels of concentrate and different forages, and showed that the mean pH was 7.30, regardless of the level of concentrate (20,40,60, and 80%) and forage evaluated. Normally, in in vivo studies on ruminal parameters, the ruminal liquid has a lower pH in relation to that observed in vitro; this may be due to the absorption dynamics of short-chain fatty acids and ammoniacal nitrogen in the rumen, which does not occur in in vitro studies.…”
