Efek suplementasi tepung kulit jengkol pada pelepah sawit fermentasi terhadap profil mikroba rumen dan produksi gas metan in vitro

<p class="MDPI17abstract"><strong>Objective: </strong>This research was aimed to evaluation the effect of supplementation jengkol peel powder in fermented oil palm fronds on rumen microbes profile and methane production <em>in vitro</em>.</p><p class="MDPI17abstract"><strong>Methods: </strong>The used design factorial randomized block with four treatments at 0, 2, 4, 6% groups as replications. The observed variables were (population total bacteria, cellulolytic, protozoa), production, partial <em>volatile fatty acid</em> (VFA) proportion acetate/propionate (A/P) ratio. data analyzed using ANOVA different among means examined by Duncan Multiple Range Test (DMRT).<strong></strong></p><p class="MDPI17abstract"><strong>Results: result showed that substrate increased (P<0.05) cellulolytic bacteria population. Jengkol much 4 decreased protozoa population, acetate A/P Supplementation 2% propionate production.<strong></strong></p><p class="MDPI17abstract"><strong>Conclusions: </strong>In conclusion, can be substituted did not disturb profile, proportion, ratio vitro</em>.<strong></strong></p>
