**Cowra, NSW** – Australian farmers are taking a proactive approach to reducing their greenhouse gas emissions by adopting new technology that “breathalyses” their cattle. The devices, developed by Agscent and Optiweigh, track methane emissions from each breath and burp, providing valuable data on individual animal performance and overall herd methane output.
This innovative technology comes at a crucial time, as Australia aims to reduce its methane emissions by 30% by 2030. The agricultural industry, particularly livestock, is a significant contributor to national emissions. Cattle, sheep, and goats are responsible for around 70% of NSW’s agricultural greenhouse gas emissions, primarily due to methane released during digestion.
The devices, which resemble a feeding station, lure cattle with molasses. As the animals feed, their weight and methane emissions are recorded, allowing farmers to make informed decisions about feed plans and breeding strategies.
“Every single breath tells a different story,” explains Dr. Daniela Carnovale of Agscent. “We’ve been able to map the breath to give us insights on pregnancy, disease and methane.”
The technology has been implemented on five farms in NSW and Queensland, as well as a farm in Kansas, USA. Initial results indicate a strong correlation between an animal’s body weight and methane emissions. This data can be used to breed cattle with lower methane production and optimize feed for better efficiency.
“I’m trying to tell people not to be embarrassed about the amount of methane our animals produce,” says Jon Wright, a cattle farmer near Cowra who has been using the technology since August. “It’s exciting if we can improve efficiency and productivity and show a good story for the industry to show we are taking responsibility for the emissions we’re producing.”
The NSW Department of Primary Industries is also actively researching alternative pasture species and feed additives that could further reduce methane emissions.
Professor Luciano Gonzales, Chair of the University of Sydney’s Sustainability Livestock Production committee, highlights the potential of this technology: “It has huge potential given it can provide real-time information on how much gases are being emitted, it’s a powerful tool for the industry.”
With this innovative approach, Australian farmers are leading the way in sustainable agriculture, taking responsibility for their impact on the environment while ensuring the future of the livestock industry.
