Abstract
The effects that are implemented by OPLE on the in vitro production of methane, total gas and gas
production rate were determined. During this phase, the determination of the methane production and
gas (in vitro) was conducted. The diets (experimental) where Ctrl, T1 and T2 (0, 300 and 600 mg
OPLE \ kg DM diet). In this study, a noticeable lessening in the production of methane and gas (in
vitro) in OPLE groups for treatment was observed and analogized to a group whose feed was not
complemented with OPLE, known as the control group. Total gas production was significantly
(P<0.05) reduced by the experimental OPLE treatments which were for Ctrl, T1 and T2, 41.58, 38.67
and 38.27 (mL/250mg DM), respectively. And the gas production rate for Ctrl, T1 and T2 was 1.73,
1.61 and 1.59 (mL/hour of incubation), respectively, which are showing a significant (P<0.05)
reduction in OPLE treatment groups. Furthermore, OPLE supplement suppressed methane production
after 24 hours of incubation and the effect was significant (P<0.05).
