The aim of this study was to determine the effect of essential oil of oregano (Origanum vulgare) on in vitro gas production, metabolisable energy (ME), organic matter digestibility (OMD), volatile fatty acid (VFA) production, true dry matter digestibility (TDMD) and neutral detergent fibre digestibility (NDFD) of alfalfa hay, maize silage and barley grain. The gas production from slowly fermentable fraction (b), VFA, ME, OMD, TDMD and NDFD decreased with increasing level of oregano oil. It is concluded that oregano oil inclusion inhibited overall fermentation process.
