One project investigating impacts of feed additives on reducing methane emissions from the burps of beef cattle over their lifetime was allocated almost €1.5 million.
The research will look at ways of reducing methane emissions in Irish beef systems through strategic use of feed additives and early-life interventions.
The vast majority of methane - a greenhouse gas - released by cattle during digestion is by belching, rather than flatulance.



a good additive is seaweed, and has already been commercialised in Tasmania years ago
