> Enteric CH4 is a consequence of anaerobic fermentation of feed organic matter (OM) by a microbial consortium that produces substrate CO2 and hydrogen in a reduction pathway used by methanogens (Morgavi et al. 2010). Feed additives have been used to interfere with this pathway or otherwise reduce the numbers of functional methanogens. (https://doi.org/10.1071/AN15576 https://doi.org/10.1071/AN15576) i guess that means they stay as co2 and hydrogen, but the paper also says that fermentation efficiency is decreased which ends up making the cows eat fewer molecules.
