HIGH tech portable chambers for measuring methane emissions from sheep are being used in the UK for the first time.
Scientists at Scotland’s Rural College (SRUC) have unveiled their New Zealand-designed Portable Accumulation Chambers (PACs) as the latest tool in mitigating agricultural greenhouse gases.
The trailer-mounted chambers can predict methane emissions in individual sheep from a variety of systems, including at pasture, as well as in multiple locations.
Scientists can collect air samples and then analyse methane concentration, showing which genetics, feed types and systems generate the highest emission levels.
Dr Nicola Lambe from SRUC, who is leading the PACs project, said: “There is an urgent need to mitigate greenhouse gas emissions from sheep. Recent figures show there are more than 1.2 billion sheep in the world, producing around seven million tonnes of methane into the atmosphere.
“Despite the fact resource efficiency and greenhouse gas emissions are global priorities, there are few examples around the world of research to implement breeding strategies to directly tackle these issues in sheep.
“This is largely due to the difficulty in recording feed consumption and greenhouse gas emissions on an individual animal basis, especially in grass-based systems. The Portable Accumulation Chambers will play an important role in starting to address this issue.”
