A study conducted at Gyeongsang National University investigated the effects of Pinus koraiensis cone essential oil (PEO) on methane emissions in goats during the fattening phase. The study found that the administration of PEO reduced methane concentrations in the exhaled gas by 12.0-13.6%. Although the microbial composition in the rumen was not altered, certain microbial interactions and metabolites were affected by PEO supplementation. The study suggests that PEO administration can reduce methane emissions in goats through various mechanisms, such as formate, sulfur, methylated amines metabolism, and propionate production. This research provides valuable insights for future strategies to mitigate methane emissions while maintaining animal production and health. [Extracted from the article]
