Inclusion of different exogenous fibrolytic enzymes to dry jowar fodder and their effect on in vitro total gas production

Aim: Our objective was to estimate in-vitro gas production from dry jowar fodder added with different concentrations of exogenous fibrolytic enzymes (EFEs) like neutral cellulase and fungal xylanase. Materials and Methods: 34 different samples of dry jowar fodder were prepared according to different concentrations of neutral cellulase, fungal xylanase and neutral cellulase + fungal xylanase (1:1). Sample not containing any enzymes was considered as the control group. These 34 samples were subjected to further in vitro gas production analysis. Results: Statistically, significantly higher (P<0.05) potential gas production was recorded for 0.7 % at 6 hr period, 0.7 % at 12 hr period, 0.7 %, 0.8 % at 18 hr period and 0.7 %, 0.8 % at 24 hr period in the samples treated with neutral cellulase. Significantly higher potential gas production was recorded for 0.5 %, 0.8 % at 6 hr period, 0.5 %, 0.6 %, 0.8 % at 12 hr period, 0.8 % at 18 hr period and 0.5 %, 0.6 %, 0.8 % at 24 hr period in the samples treated with fungal xylanase. Significantly higher potential gas production was recorded for 0.6 %, 0.6 %, 0.8 % at 6 hr period, 0.6 %, 0.8 % at 12 hr period, 0.6 %, 0.8 % at 18 hr period and 0.6 %, 0.8 % at 24 hr period in the samples treated with mixture of neutral cellulase + fungal xylanase (1:1).
