Short summary
Archaeol is a cell membrane lipid of methanogenic archaea excreted in feces. This study, based on respiration chamber measurements, revealed that fecal archaeol concentration offers some potential in serving as a proxy for individual methane emission but that it also cannot be implemented easily on a farm because diet composition, dry matter intake, and the time for fecal sampling have to be taken into account.
