An in vitro rumen fermentation study was conducted to evaluate the effect of supplementation with solid state fermented biomass (SSF) in total mixed rations (TMRs) on total gas production, methanogenesis and dry matter digestibility by using the rumen liquor of adult Surti buffaloes. SSF biomass was supplemented at 0, 1, 2, 3, 4, 5, 6, 7, and 8% with TMR (65% wheat straw and 35% concentrate) for in vitro gas production trials. The results of the in vitro study revealed significantly (P < 0.05) greater IVDMD (58.43%) and lower CH 4 production (3.58 ml CH 4 /100 mg DDM) at a 3% level of SSF biomass addition in TMR. Based on the overall results of in vitro studies, 3% SSF biomass supplementation was found to be most suitable for further in vivo studies in adult Surti buffaloes.
