Potential of condensed tannins for the reduction of emissions of enteric methane and their effect on ruminant productivity

Methane (CH4) gas is a by-product of anaerobic fermentation of carbohydrates in the rumen of ruminant species. Agriculture contributes with 47% of anthropogenic emissions of CH4, being the ruminants responsible for 39% of enteric emissions of CH4. This greenhouse gas (GHG) has twenty-five times high...
