Cattle produce large amounts of methane as they digest their food and then belch out most of it through their mouths.

A herd of 200 cows can produce annual emissions of methane roughly equivalent in energy terms to driving a family car more than 100,000 miles 180,000km on more than four gallons 21,400 litres of petrol.

Researchers from University College Dublin found however, by adding two per cent of fish oil to the animals feed the amount of methane is reduced by around a fifth.

The omega 3 fatty acids found in fish oils can also help the heart and circulatory system and improve meat quality.

Speaking at the Society for General Microbiology meeting in Harrogate, Dr Lorraine Lillis, one of the researchers, said the study could help the agriculture industry cut emissions.

She said: The fish oil affects the methaneproducing bacteria in the rumen part of the cows gut, leading to reduced emissions.

Understanding which microbial species are particularly influenced by changes in diet and relating them to methane production could bring about a more targeted approach to reducing methane emissions in animals.

The UK is committed to cutting greenhouse gases by 80 per cent by 2050.

More than a third of all methane emissions in the UK is produced by farm animals. By volume, methan longchamps travel bag e is 2 longchamps travel bag 0 times more powerful at trapping solar energy than carbon dioxide making it a potent greenhouse gas.

Jonathan Scurlock, an adviser at the National Farmers Union, said farmers were willing to modify feed in order to reduce emissions but at the moment there are few affordable options on the market and he encoura longchamps travel bag ged more research into the area. longchamps travel bag
