Abstract

The objective of this study was to investigate the effects of 11 active compounds of essential oils (ACEO) on rumen fermentation characteristics and methane production. Two trials were conducted. In trial 1, ACEO (eugenol, carvacrol, citral, limonene, 1,4-cineole, p-cymene, linalool, bornyl acetate, alpha-pinene, and beta-pinene) at a dose of 1,000 mu L/L were incubated for 24 h in diluted rumen fluid with a 70: 30 forage: concentrate substrate (16.2% crude protein, 36.6% neutral detergent fiber). Three fistulated Holstein cows were used as donors of rumen fluid. The reduction in methane production was observed with nine ACEO (up to 86% reduction) compared with the control (p
