Abstract The effect of Agolin Ruminant, a blend of essential oils, on methane (CH 4)
emissions were investigated in two in vivo experiments and in four in vitro experiments. In
the in vivo experiments, four lactating dairy cows and four beef heifers were supplemented
0.2 g/d of the essential oils (ca. 2–4 ppm m/v) during an eight-weeks period, where the first
two weeks served as control (no essential oils supplementation). In dairy cattle, essential
oils tended to decrease the daily CH 4 emissions (g/d) and CH 4 relative to dry matter intake …
