Feeding Cattle Seaweed Cuts Methane Significantly

submitted by newtboy

1 year 11 months 3 weeks ago

UC Davis and other institutions have been experimenting with seaweed added to cattle feed to reduce methane emissions. Results are very encouraging, showing reductions in methane production from between 52% to over 90% in some cows with only 1-2 % of their feed replaced with seaweed.
Unfortunately, the best results come from strains that are notoriously difficult to grow, so the next step is developing aquaculture to farm enough to add it to cattle feed nation (and eventually world) wide.
