Effect of Dried Rumen Content and Carbohydrate Sources in Ensiling Process on Corn Stover Silage (Zea mays) to Increasing Nutrient Contents and InVitro Digestibility

The purpose of this study was to determine the effect of addition of inoculant (dried rumen content) and/or additives (rice bran and cassava flour) and incubation time on nutrient content of Dry Matter (DM), Organic Matter (OM), Crude Protein (CP), Neutral Detergen Fiber (NDF), in vitro DM digestibility and in vitro OM digestibility of corn stover silage. Corn stover silage was made 100% corn stover with inoculant and/or additives with treatments P0 (without addition as control), P1 (4% additives), P2 (4% mixed of inoculant and additives (1:0,5 weight ratio), and P3 (4% inoculant + 4% additives) with incubation time i.e. 2, 4 and 21 days. The incubation time is 0 days for comparison before the ensilage process. The variables observed were DM, OM, CP, NDF, in vitro DM digestibility and in vitro OM digestibility. Data were analysis of variance (ANOVA). The method used in the nutrient content test is a 4x3 factorial Completely Randomized Design (CRD) with 4 replications and continued with Duncan's Multiple Range Test (DMRT). The method used in the digestibility test is an experimental method with a CRD with 4 treatments and 4 replications. The results showed that addition of inoculant and/or additives gave highly significant effect (P<0.01) on DM, OM, CP, NDF, significantly effect (P<0.05) on DM digestibility, but not significantly different OM digestibility. The incubation time showed gave highly significant effect (P<0.01) on DM, OM
