Fermentation Characteristics of Corn Stover and Gliricydia sepiumCombination Silage with Different Presentations

Abstract

The problem on agricultural waste utilization as forage source was its low quality and perishable character. As effort to improve the utility of agricultural waste, there is need both preservation process and nutrient quality improvement. Corn stover was one of common agricultural waste with huge number of biomass for forage source. The presence of corn stover in Indonesia while harvest season need to be overcome by fermentation technique, such as silage. Meanwhile, Gliricydiasepiumknown as high crude protein content, which suitable for feed protein source. Corn stover and Gliricydiasepium combination silage to be expected could improve feed quality and continuity. This research was aimed to compare the fermentation characteristicsof Corn Stover and Gliricydiasepiumcombination silage with different percentation (10, 30, and 50%) of Gliricydiasepium as the treatments. The research variables were organoleptic (odor and color), chemical (pH and Dry Matter (DM)) and silage Fleigh Value. The result showed that using 10 and 30% Gliricydiasepium on silage have higher DM (32.51±1.68 and 34.16±4.47 vs. 27.28±0.37) and lower pH (3.34±0.07 and3.36±0.04 vs. 3.47±0.09)compare with 50%,that’s make Fleigh Value of them was higher (136.57±4.91 and 138.91±9.55 vs.120.67±3.84) and all treatments were classified as excellent. The organoleptic variable showed that all combinations have similar green to yellow fresh color with acid fermentation odor. Based on silage fermentation characteristic in this research, theimprovement of corn stover silage quality by using Gliricydiasepium was recommended, and this need further research about silage crude protein content.
