Description: Biogenic methane from ruminants is a potent greenhouse gas that is produced and released from methanogens in the rumen. The vast majority of ruminant methane research worldwide has been conducted within ‘high input’ indoor environments, where the animals are offered diets that differ considerably to grazing systems. Recent advances in the state of the art enable routine measurement of methane emissions with grazing dairy cows. The aim of this research is to understand more clearly, and ultimately develop mitigation strategies for enteric methane emissions, relevant to grazing dairy systems. The project will aim to quantify more accurately enteric methane emissions of Irish grazing

dairy cows, establish the impact of variations in pasture quality, mass, and availability, as well as the influence of the presence of clover and multispecies swards, and the effect of cow characteristics and breed. Seasonal variation in enteric methane emissions will also be investigated
