The Holland headquartered Royal DSM, has got approval from the Brazilian and Chilean authorities to commercialise its methane-reducing feed additive for ruminants Bovaer. According to 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 percent for dairy cows and even higher percentages (up to 90%) for beef cows. Bovaer has recently been filed for registration in Europe. Registrations of the feed additive in other regions will follow.
