The trial of Bovaer, a feed additive claimed to reduce methane emissions in dairy cows, has sparked widespread debate online in the UK. Protests include consumers pouring milk down sinks and toilets, alongside safety concerns about the additive’s compounds. While experts defend Bovaer’s safety and efficacy, misinformation linking it to Bill Gates and unfounded conspiracy theories circulate on social media. Major supermarkets are participating in the trial, despite calls for reviews from some politicians and farmers wary of the product.
