Researcher follows dairy cows’ carbon footprints from barn to field

Wisconsin – Last spring, University of Wisconsin–Madison researcher Michel Wattiaux began using a specialized device to measure the methane being exhaled or belched by a group of Holsteins and Jerseys.

It was the first step in an ongoing study by dairy scientists, engineers and agronomists to see how a cow’s breed and forage consumption affect the greenhouse gases generated by her gut and her manure.

The U.S. dairy industry has set a goal of reducing its greenhouse gas emissions by 25 percent by the year 2020, and UW–Madison researchers are helping identify strategies to accomplish that. | For the full story, CLICK HERE.
