Producing a liter of milk in California emits less greenhouse gas and uses less land and water than it did in 1964, according to a recent study from researchers at the University of California, Davis.

“We compared 1964 through 2014 and found a 50 percent reduction in greenhouse gases to produce the same quantity and quality of milk,” said senior author Ermias Kebreab, professor and Sesnon Endowed Chair in the Department of Animal Science at ��ɫ��Ƶ. “The magnitude of change is surprising.”

Can Seaweed Cut Methane Emissions on Dairy Farms?

Seaweed may be the super food dairy cattle need to reduce the amount of methane they burp into the atmosphere. Early results from research at ��ɫ��Ƶ indicate that just a touch of the ocean algae in cattle feed could dramatically cut greenhouse gas emissions from California’s 1.8 million dairy cows.

Pawnee Farm Arlinda Chief was one of the most prolific bulls in the history of Holstein cattle breeding — but he also introduced a lethal gene into the population, responsible for an estimated half million spontaneous abortions worldwide. Now researchers at ��ɫ��Ƶ and the University of Illinois Urbana-Champaign have identified the mutation responsible, enabling ranchers to test for and avoid it.
