A little algae in cattle feed could reduce methane emissions by as much as 82%, according to new findings from researchers at the University of California at Davis. The results, published in the journal PLOS ONE, could pave the way for sustainable livestock production.
Over the course of five months last summer, Kebreab and Roque added scant amounts of seaweed to the diets of 21 beef cattle and tracked their weight gain and methane emissions. Cattle that consumed approximately 80 gram doses of seaweed gained as much weight as their herd mates while emitting 82% less methane into the atmosphere. Kebreab and Roque build on their earlier work with dairy cattle, which was the world’s first experiment that was reported to use seaweed on cattle.
