This paper provides an update of research on enteric methanogenesis by reporting data from recent case studies on promising methane (CH4) mitigation strategies and biomarkers to estimate CH4 emissions in cattle. We demonstrated an additive and persistent effect between lipids and nitrate for reducing rumen methanogenesis in cows. This proof of concept opens up a range of possibilities for designing new strategies to increase CH4 abatement. Despite a high individual variability in daily CH4 emissions among animals, the dairy cow ranking was not stable over time across the different diets. Our data highlight the importance of phenotyping animals across environments in which they will be expected to perform. In growing bulls, enteric CH4 methane emissions are positively associated to residual feed intake in growing bulls suggesting that animals that ingested food in excess of their maintenance and growth requirements emitted more CH4 per day with both diets. A meta-analyse approach indicated that milk fatty acids have better potential to accurately predict CH4 emissions when combined with other variables (e.g, days in milk, diet composition) compared with on their own. Inhibition of enteric methanogenesis in dairy cows induced changes in plasma metabolome highlighting metabolomic shifts and potential new markers of CH4 emissions.
