Bovaer is a dsm-firmenich feed supplement for cattle that temporarily inactivates a rumen enzyme involved in methane formation, lowering methane output from daily rations. A quarter teaspoon per head per day takes effect within about 30 minutes, then breaks down into compounds already present in the rumen without passing into milk or meat.

The additive reduces methane emissions by an average of 30 percent in dairy cattle and up to 45 percent in beef cattle, backed by more than 110 peer-reviewed studies and trials across 20 countries. It is authorized for sale in 70 countries and is fed to more than 500,000 cows across 25 countries.
