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.
