An experiment was conducted to study the effect of supplemental malic acid on methane mitigation and rumen fermentation characteristics for dairy cattle in forage based diet by in vitro gas production technique (IVGPT). The methane emission and methane (ml) per 100 mg of truly digested substrate were significantly (p<0.01) decreased in 0.26 % malic acid added group than other treatment groups. The volatile fatty acid and propionic acid were significantly (p<0.01) increased in malic acid added groups than control. It was concluded that the minimum concentration of malic acid at 0.26 % was able to reduce the methane to the maximum extent by IVGPT.

Key Words: Malic acid, methane, rumen fermentation, dairy cattle
