Feeding Cattle Seaweed Reduces Their Greenhouse Gas Emissions 82 Percent

"A bit of seaweed in cattle feed could reduce methane emissions from beef cattle as much as 82 percent, according to new findings from researchers at the University of California, Davis. The results, published today in the journal PLOS ONE, could pave the way for the sustainable production of livestock throughout the world.

"We now have sound evidence that seaweed in cattle diet is effective at reducing greenhouse gases and that the efficacy does not diminish over time," said Ermias Kebreab, professor and Sesnon Endowed Chair of the Department of Animal Science and director of the World Food Center. Kebreab conducted the study along with his Ph.D. graduate student Breanna Roque.

"This could help farmers sustainably produce the beef and dairy products we need to feed the world," Roque added."
