Thanks to special bacteria in their stomachs, kangaroo flatulence contains no methane and scientists want to transfer that bacteria to cattle and sheep who emit large quantities of the harmful gas.
"Fourteen per cent of emissions from all sources in Australia is from enteric methane from cattle and sheep," said Athol Klieve, a senior research scientist with the Queensland Government.
Researchers say the bacteria also makes the digestive process much more efficient and could potentially save millions of dollars in feed costs for farmers and graziers. "Not only would they not produce the methane, they would actually get something like 10 to 15 per cent more energy out of the feed they are eating," said Dr Klieve.
I've been wondering about this ever since I learned about fecal bacteriotherapy!
