Ramie leaves silage qualities improvement by addition 20% W/W FS of absorbance and water soluble carbohydrates (WSC) sources prior to 42 days of ensiling time have been done in two experiments. Experiment-1 examined three types of the additives (cassava meal, pollard and coarse grinding corn) for their capacities to improve physical (color, odor, texture and spoilage), fermentative (pH, protein degradation, organic acid profiles) and utilities characteristics of the silages for ruminants (rumen fermentabilities and digestibilities) in vitro. The silages had bright greenish brown of color, lactic acid odor and firm textures, categorized as highly fermentable and digestible feeds (dry matter digestibility >72%). Compare to other additives, cassava meal produced better silage based on their physical chemical characteristics and drop silage pH faster than other additives. However, high butyric acid and protein degradation proportions in the silage were not seem in line to these data. Coarse grinding corn failed to do its function therefore produced poor silage quality. Second experiment was aimed to confirm the previous results. Five types of additives (cassava meal, pollard, fine grinding corn, rice bran, and cassava extract meal) of the same functions were examined. The results confirmed that cassava meal still produce better ramie leave silages than other additives. However, this time, all additives successes to serve their functions therefore produce good ramie leave silage qualities.
