UC Davis tests whether seaweed in cattle feed reduces cows’ methane emissions

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 tha
