A prototype vaccine from ArkeaBio, a US start-up, cut methane emissions by 13 per cent in a first trial involving 10 cows, offering a potential way to reduce the huge climate impact of cattle farming
A start-up has developed a vaccine that cuts methane emissions from cow burps, with plans for a commercial launch within three years.Cattle produce methane as a byproduct of fermenting grasses and hay in their rumen, the first part of their digestive tract. Agriculture is the biggest source of human-caused methane pollution in the world, largely driven by the burps and farts from the billion cattle farmed globally.
