Fish oil cuts the gas

April 3, 2009

If this had been published a couple of days later I’d have put it down to April Fools Day but I think its genuine.

Scientists have found that fish oil reduces burps  in cows.

Researchers from University College Dublin found however, by adding two per cent of fish oil to the animal’s 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 methane-producing bacteria in the rumen part of the cow’s gut, leading to reduced emissions.

Adding fish oil to feed for cattle in feedlots probably isn’t difficult, it may take a bit of ingenuity to get it into cattle which graze pasture as they do in New Zealand. It would also have to be done reasonably cheaply because added costs will be resisted by farmers and consumers.
