Bovaer® is a feed additive for cows (and other ruminants, such as sheep, goats, and deer) researched and developed over 10 years by DSM. Just a quarter teaspoon of Bovaer® per cow per day suppresses the enzyme that triggers methane production in a cow’s rumen and consistently reduces enteric methane emission by approximately 30%. It takes effect immediately and it’s safely broken down in the cow’s normal digestive system. As soon as the additive is not fed anymore, full methane production resumes and there are no lasting effects in the cow. The feed additive Bovaer® therefore contributes to a significant and immediate reduction of the environmental footprint of meat, milk and dairy products.
