Mitigation of Enteric Methane Emissions from Dairy Cows

Enteric methane is a major contributor to global and U.S. agricultural GHG emissions and can represent 50% of a dairy farm’s GHG emissions. This fact sheet describes nutrition, feed, and management strategies to reduce methane emissions.

Decreasing enteric methane emission from dairy cows with no negative effect on milk production

This study was undertaken to investigate the effect of a methane inhibitor on enteric methane emissions from lactating dairy cows. The experiment demonstrated that, under industry-relevant conditions, the inhibitor persistently decreased by 30% enteric methane emissions, without negatively affecting animal productivity.
