Methane emissions from cows (burping rather than farting, apparently) are a serious problem, contributing to climate change due to the huge numbers being bred for our insatiable appetite for a good steak and milk. Now though researchers in Brisbane, Australia are investigating breeding low-methane livestock and modifying feeding regimes to keep the emissions low.
They will be monitoring gas build up using a small submarine like sensor with wings that keep it in the cows rumen – the chamber in the stomach where gas production is greatest. Using infra-red sensors they can assess the conditions that create the most gas and adjust feeding accordingly.
Good news for those of us who enjoy a good sirloin.
