Seaweed Diet Could Help Combat Methane Emissions from Cattle

Scientists at the University of California have found a red algae seaweed that reduces bovine methane production by as much as 50% when small amounts of the seaweed are added to their feed. Now scientists are exploring how they might be able to cultivate Asparagopsis taxiformis on a large scale, and how they might increase its concentration of bromoform, the chemical responsible for halting methane production in cattle. Researchers say there is much work to be done to understand the complete life cycle of the seaweed and the best way to cultivate large quantities of it that would be needed to use it effectively as a cattle feed additive.
