Seaweed may reduce cows' greenhouse gas emissions, new study finds

DAVIS, Calif. (KGO) -- University of California researchers may have found a way to make cattle more climate-friendly: feed them seaweed.

UC Davis researchers say methane emissions were reduced by more than 30 percent in Holstein cows that ate feed mixed with just a little bit of ocean algae in a recent study.

Methane is a potent greenhouse gas, more potent even than carbon dioxide.

Scientists are calling the findings surprising.

They're planning a six-month study of a seaweed-infused diet in beef cattle starting in October.
