Methane inhibitors could be fed to livestock in New Zealand as soon as September. The Environmental Protection Authority expects to decide by September on an application from Dutch multi national DSM to introduce a feed additive to reduce methane emissions in livestock. The EPA formally received the application for the approval of a substance containing the active ingredient 3-NOP, commonly known as Bovaer. The compound works by temporarily blocking the enzyme responsible for methane formation. The EPA says from a regulatory perspective, substances for climate change mitigation are new to New Zealand. A spokesperson for DSM said Bovaer has been cleared in more than 45 countries. Fonterra began trials with Bovaer in 2021 and DSM says trials show adding about a quarter of a teaspoon of the supplement to feed results in a 30% methane reduction.
