Abstract

Abstract This study determined the effects of geranium essential oil (0%, 0.5%, 1%, and 1.5%) on the in vitro ruminal fermentation of a ruminant diet consisting of 60% concentrate and 40% forage. Gas production (GP), carbon dioxide (CO 2 ), methane (CH 4 ), total and individual short-chain fatty acids (SCFAs), and nutrient degradability were measured. The 1.5% essential oil inclusion resulted in the highest (P
