Abstract


Rice bran quality is subjected to instability due to season, processes and
counterfeiting. The aim of this determine was to study the effect of Natuzyme® addition on
low-quality rice bran on the concentration of methane gas, pH value and dry matter
digestibility by in vitro technique. Two series of the experimental design with 4 treatments; P0
(Rice Bran), P1 (Rice Bran + Natuzyme® 0.02%), P2 (Rice Bran + Natuzyme® 0.04%), P3
(Rice Bran + Natuzyme® 0.06%) and 5 replications were applied on completely randomized
design to determine the hypothesis. The observed parameters were the concentration of
methane gas, pH value and dry matter digestibility in vitro. The results showed that the
addition of different Natuzyme® on low-quality rice bran showed no significant difference (P>
0.05) on dry matter digestibility and pH value but had significant difference (P <0.05) on the
concentration of methane gas. The addition of Natuzyme® on low-quality rice bran has not
been able to increase dry matter digestibility and pH value but decreasing the concentration of
methane gas.
