Conspiracy theory on methane reducing cow feed a 'wake-up call', scientists say

Bovaer is the name given to 3-nitrooxypropanol, or '3-NOP', one of a range of additives that are given to cattle to aid digestion and reduce their flatulence, which is a significant cause of methane emissions. 

Scientists say a recent methane-related conspiracy theory is “a wake-up call” for the industry, reminding them they need to communicate better and more directly with the public.

Over the last few months, Bovaer, a cattle feed additive that is proven to reduce emissions of the greenhouse gas, has been at the centre of a swirl of misinformation that has even drawn in billionaire Bill Gates.
