The Holland headquartered Royal DSM, has got approval from the European Union to commercialize its methane-reducing feed additive for ruminants Bovaer. According to DSM just a quarter teaspoon of the 3-nitrooxypropanol containing 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 percent for dairy cows and even higher percentages (up to 90%) for beef cows.
