A University of Adelaide-led study will investigate if mixing a variety of compounds, including biserrula, into cow feed that contains seaweed, can reduce the amount of methane produced by livestock.
The study will also breath test livestock to record methane levels using a low-cost device that will make it more accessible for farmers.
The burps and farts of cows produce methane, a greenhouse gas that has 21 times more global warming potential than carbon dioxide and is accumulating in the atmosphere at the rate of one per cent per year.
