Cows in glass tanks help to reduce methane emissions

In the future, the breeding of the climate-friendly cow can be speeded up by using genetic information. A recent study identifies areas in the cow's genotype which are linked to the amount of methane it produces. Cows subjected to study did not unnecessarily chew their cuds when being placed in glass cases.Of the greenhouse gases produced by humans, 16 per cent consists of methane, of which one third originates in cattle production: more than one billion cattle graze the planet, and each of them emit around 500 litres of methane every day, thereby warming up the climate.Could it be possible to produce a cow with lower methane emissions through the means available for breeding? The genotype and feed affect a cow's microbial make-up and functioning. Microbes in the cow's intestine and rumen on their part play a key role in the functioning of the cow's entire biological system. "A similar interaction was previously detected in humans," says Johanna Vilkki, professor at Luke.
