ResumeEssential oils from African basil (O. gratissimum) have shown the potential to modify rumen microbial fermentation and reduce ruminal CH4 production from grass forages in in vitro batch cultures. However, it is not known whether the effects of EO on rumen microbial fermentation attenuate over time. The objective of this study was to examine the effects of African basil EO at 0 (control), 100, 200 and 400 mg L-1 incubation medium on microbial fermentation and CH4 production in the Rumen Simulation Technique (RUSITEC) using A. gayanus grass as a substrate. African basil EO quadratically affected (P < 0.05) CH4 production, gas production and the pH of fermenter liquid. Total VFA production was linearly decreased (P < 0.05) by African basil EO along with a shift in VFA profile towards less propionate and more acetate and butyrate. African basil EO quadratically altered (P < 0.05) apparent DM, NDF digestibility, 15N incorporation into total microbial protein and the total production of microbial protein. This study confirms that EO from African basil quadratically affected CH4 emissions arising from the ruminal fermentation of A. gayanus grass mainly by reducing overall digestibility of the forage.
