The effects of animal-produced ethane missions on the climate is one of the most hotly debated topics in agriculture today.
Now a trial of high-tech portable chambers which can measure the emissions in sheep is being carried out in the UK for the first time.
The units – known as Portable Accumulation Chambers (PACs) – are a New Zealand invention, but the project in the UK is being spearheaded by Scotland’s Rural College (SRUC).
The PACs can be used in a variety of locations and situations. They allow scientists to collect air samples from which they anlyse the concentration of methane. They then look at factors such as genetics and feed types to determine which cause the highest methane levels.
