DAVIS, Calif. (AP) — University of California researchers are feeding seaweed to dairy cows in an attempt to make cattle more climate-friendly.

UC Davis is studying whether adding small amounts of seaweed to cattle feed can help reduce their emissions of methane, a potent greenhouse gas that's released when cattle burp, pass gas or make manure.

In a study this past spring, researchers found methane emissions were reduced by more than 30 percent in a dozen Holstein cows that ate the ocean algae, which was mixed into their feed and sweetened with molasses to disguise the salty taste.
