Active rumen manipulations by use of Solid State Fermentation technique which provide crude biomass with microbes and active fiber degrading enzymes leads to better nutritive values of high fibrous feeds with improved production performance. Considering above facts present study was conducted in two phases (in vitro and in vivo) to evaluate the effect of SSF biomass on productive performance of lactating buffaloes. On incubating TMR prepared according to farmer feeding schedule which were further supplemented with increasing level of SSF biomass (0, 1, 2, 3, 4, 5, 6 and 7%) replacing cereal straw for in vitro studies. It was found that IVDMD (67.08 vs. 60.64%) and IVOMD (67.55 vs. 60.47%) was most significantly improved at 4% SSF supplemental level having CMCase (170 U/g), FPase (60 U/g), Xylanase (468 U/g), Laccase (270 U/g), MnP (488 U/g) and LiP (298 U/g) enzyme activities. Accordingly, in vitro methane production was also most significantly decreased at 4% SSF level (0.85 vs. 1.38 ml/100 mg DDM) by 38.40% as compared to control. The study revealed that incorporation of SSF biomass at 4% level in ration of lactating buffaloes would be helpful to get beneficial effects.EnglishThesis
