Bovaer is an innovative feed additive developed by DSM to significantly reduce methane emissions from ruminants. The active ingredient, 3-NOP (3-nitrooxypropanol), inhibits an enzyme involved in methane production in the rumen. This results in a 30% reduction in emissions for dairy cattle and up to 40% or more for beef cattle. A small daily dose per animal is sufficient, and the substance is completely broken down in the digestive tract without leaving any residues in milk or meat.
