Effect of essential oils on the production of methane in the in vitro fermentation of Koronivia grass
The objective was to evaluate the increasing use of garlic, sesame, and cinnamon oil in the production of CH4 in 60 d in vitro regrowth of Koronivia grass. The addition of 0, 2.5, 5.0, 5.0, 7.5, and 10 % garlic, cinnamon, or sesame oil was evaluated in an in vitro fermentation using a 60-d regrowth of Koronivia grass as substrate. The variables evaluated were cumulative CH4 production at 12, 24, 36, 36, 48, and 72 h; dry matter degradation (DMD), and CH4 production kinetics estimators (A= CH4 production potential, b= CH4 production rate constant, and k= lag time). The CH4 production and the DMD were analyzed with a completely randomized experimental design and orthogonal contrast. The estimators were subjected to a descriptive analysis. An increase of garlic oil and cinnamon linearly reduced CH4 production at 12, 24, 36, 48, and 72 h. The DMD decreased linearly with the use of any of the three oils (P<0.05). The highest value of A was obtained with 2.5 % garlic oil, and the highest value of k and b, with 10 % cinnamon oil. In conclusion, the use of garlic and cinnamon oils resulted in a linear decrease of Koronivia grass CH4 and Koronivia grass DMD under in vitro conditions.
