With its burps and farts, a dairy cow emits as much methane every year as a car driven 20,000 kilometers. Ottawa has just authorized the marketing of a feed additive that could transform the fight against global warming on the farm. 3-NOP could reduce methane emissions from dairy cows by an average of 30%, and from beef cattle by an average of 45%.
How does it work?
Methane is formed in cows' rumen鈥攖he front compartment of their stomach鈥攄uring digestion.
