Organic matter digestibility (OMD), methane gas production (CH4), short chain fatty acids (SCFA) and metabolizable energy (ME) were evaluated using in vitro gas production technique. Data generated were subjected to appropriate statistical analysis. From the results, parameters assessed were significantly (P<0.05) improved among the treatments. Ensiling significantly improved the nutritive qualities with respect to the cultivars. The assayed phytochemicals were at tolerable levels and would not hinder nutrients absorption, if fed to ruminants.

Hence, Samsorg-14 sweet sorghum cultivar was the best of all the cultivars and could serve as protein/energy source in ruminants’ diet vis-à-vis its methanogenesis, which invariably could contribute to greenhouse gas emission.
