Tracing cow's methane emissions via the milk
There is a link between the milk composition and methane emission of a cow. Methane is the main greenhouse gas produced by cows but it is difficult to measure the quantity of gas an individual cow produces. While looking for ways to reduce the methane emissions through changes in feed, researchers at Wageningen University, part of Wageningen UR, discovered that the fatty acid composition in the milk also changed. It turned out that the fatty acid composition can be used as an indicator for methane emission. The scientists hope that this will result in an accurate and affordable measuring method for methane emissions.
