Incorporating haemanthamine, the chemical extract from daffodils, in livestock feeds reduced methane emissions from artificial cow stomachs by 96 percent. Daffodils are Wales’s national flower and bloom on March 1 every year, when Welsh people commemorate St David’s Day.This national flower is playing a special role in a potentially pioneering endeavor.For a while, scientists have been testing a new method using daffodils to help lower the methane emitted by livestock.
