REUTERS — The U.S. Food and Drug Administration has cleared Elanco Animal Health’s methane-reducing feed ingredient for lactating dairy cows.
One tablespoon of Bovaer per lactating dairy cow a day can reduce methane emissions by about 30 percent, or about 1.2 tonnes of carbon dioxide equivalent emissions annually, the company said.
Bovaer works by suppressing the enzyme in a cow’s rumen, where methane is produced.

Farmland rented or leased in the two provinces went from 25.7 million acres in 2011 to 29.1 million in 2021, says Census of Agriculture data.
The feed ingredient would help dairy food companies buy carbon credits from their own farms and create a value stream of $20 a cow, Elanco chief executive officer Jeffrey Simmons said.
The feed ingredient received market approval in Canada earlier this year.
