Bovaer®

Now available: A proven solution

Bovaer® is the most extensively studied and scientifically proven solution to the challenge of burped methane to date — with 100+ on-farms trials in 20+ countries and more than 70 peer-reviewed scientific studies. In every case, it has proven safe for animal, farmer and consumer. 

Bovaer® is authorized and available for sale in over 55+ countries, including the EU/EEA, Australia, Brazil, Canada, Chile, Mexico, Pakistan, Switzerland Turkey and the United Kingdom (per April 2024). 

How it works

In a cow's rumen, microbes help break down food. This releases hydrogen and carbon dioxide. An enzyme combines these gases to form methane. Bovaer® is a feed supplement that suppresses the enzyme, so less methane gets generated. Just ¼ teaspoon in a cow’s daily feed takes effect in as little as 30 minutes. As it acts, Bovaer® is safely broken down into compounds already naturally present in the rumen. 

An urgent focus on methane

Bovaer® is a feed additive that reduces enteric methane emissions, contributing to a significant and immediate reduction of the environmental footprint of meat, milk, and dairy products. On average, it reduces emissions by 30% from dairy cows and 45% from beef cattle. 

More than 100 countries have recognized methane reduction as the single most effective strategy to keep the goal of limiting global warming to 1.5 ̊C within reach. And there’s no time to lose. Rapidly reducing methane emissions can achieve near-term climate goals with additional benefits for public health and agricultural productivity.
