Sounds fishy … but it apparently works.
Scientists at the Ghent University in Belgium say adding a dash of fish oil to animal fodder could reduce the amount of methane released by livestock.
Bacteria in the fluid of the fore-stomachs of sheep normally break food down, releasing methane. But scientists found that rations containing around 4% fish oil slashed the sheep belching by 25-to-40%.
According to the U.S. Environmental Protection Agency, belches from farmyard animals account for around 22% of the global emissions of the greenhouse gas methane.
