Tropical alga can nearly halve GHG emissions from cow manure, according to research in Sweden

AT, a type of red algae, is among the most promising natural inhibitors of methane production in dairy cattle. Research has indicated that AT contains compounds that inhibit the enzyme that catalyzes the final step in methane formation in the rumen, making it an effective methane inhibitor and feed additive. Recently, an experimental study published in Frontiers in Sustainable Food Systems and conducted by researchers from the Department of Animal Nutrition and Management at the Swedish University of Agricultural Sciences in Uppsala, Sweden, has indicated that AT can also suppress GHG formation from cow manure and nearly halve methane emissions. The experiment aimed to determine whether methane production from the manure of grass-fed cows supplemented with AT was lower than that of those who were not supplemented. The researchers collected faecal samples as part of a feeding trial from six Nordic Red cows were fed a diet of grass-based silage that was supplemented or not ...
