Daffodils may present the important thing to extra sustainable livestock farming, in response to scientists who say lab exams have confirmed promising.

Adding an extract from the flowers to livestock feed diminished methane in synthetic cow stomachs by 96%.

A group of researchers at Scotland's Rural College hope that when trialled in actual cows, it may scale back methane emissions by not less than 30%.

A four-year programme of trials is now starting at farms across the UK.

On his farm in Powys, Kevin Stephens breeds cattle and grows daffodils.

He has been a part of the group creating the science behind the brand new animal feed.

"We started growing daffodils originally to produce an Alzheimer's drug, but we discovered that the daffodils also produce a compound that prevents ruminants from producing methane," he mentioned.

"So the chance to combine the two things was too good an opportunity to miss."

For farmers like him, discovering a method to farm extra sustainably may very well be a recreation changer.

"This could make a huge difference to the livestock industry," he mentioned.

"There are governments across the world currently trying to meet net-zero by either taxing livestock farmers or putting quotas on the number of livestock you can have because of this methane by product.

"This offers us a really actual alternative to alter that story."

It is estimated that half of the nation's methane emissions come from cows.

And globally, livestock produce round 14% of the world's greenhouse gasses.

Professor Jamie Newbold, professor of animal science at Scotland's Rural College, mentioned: "Our new project has three main stages.

"First creating a provide chain of daffodils and extracting the chemical substances from daffodils. Secondly, testing that the additive is protected to each animals and people, and at last, working with our farmer companions throughout England and Wales to show the additive is efficient in lowering methane manufacturing and feed prices for dairy cattle.

"This is vital because greenhouse gases and global warming is a major global challenge, and we hope our project will be part of the solution of reducing the role of ruminants in methane production."
