    New diet set to cut cows’ gas ‘emissions’

    British farmers could soon be helping to fight climate change by adapting their cattle’s diet so they break wind less frequently.

    Researchers in Wales are developing varieties of grass and clover that are easier for ruminants to digest.

    The effect is to cut the amount of methane they produce.

    Michael Abberton, of the Institute of Grassland and Environmental Research, said on Monday that cows accounted for between a fifth and a quarter of UK methane emissions arising from human activity.

    Most cattle in the UK graze on perennial ryegrass, sometimes mixed with clover. But high sugar versions of ryegrass under development at IGER, and new varieties of clover, could cut cattle’s “emissions” dramatically.

    Mr Abberton said: “Farmers can do this now [by introducing the new feeds] if they have the knowledge and the skills.”

    Some studies have suggested new feed could halve methane emissions, though Mr Abberton said the true proportion was likely to be less in practice.

    Methane is a greenhouse gas with a warming effect on the atmosphere more than 20 times that of carbon dioxide.
