Concentration of Short Chain Fatty Acid and Methane Gas of Ration Containing Different Level of Oil Palm Decanter Meal: In vitro Study

The aim of this study was to reveal the differences of concentration of short chain fatty acid (SCFA) and methane gas production from ration containing different level of oil palm decanter meal (OPDM). Four treatment rations namely P0, P1, P2 and P4 were formulated to contain forage, OPDM and concentrate. In vitro technique was applied for measuring SCFA and methane production. Production of SCFA including acetate, propionate, butyrate and the ratio of acetic, propionic acid and methane gas was significantly P less than 0.05) different among treatments. It could be concluded that OPDM in ration was suitable for dairy ruminant but it was not recommended for meat.
