Cows are a gassy bunch. As they stand in fields and munch on grass, the animals burp and fart—and, in doing so, they release billions of pounds of heat-trapping methane gas into the atmosphere. In total,

A UC Davis study found that feeding seaweed supplements to grazing cattle reduced methane emissions by 40%, promoting sustainable farming.

Supplementing the diets of grazing beef cows with seaweed in pellet form could cut their methane emissions by almost 40 percent, a new study has found. The seaweed pellets led to this plunge in

Seaweed is once again showing promise for making cattle farming more sustainable. A new study by researchers at the UC Davis found that feeding grazing beef cattle a seaweed supplement in pellet form reduced their methane emissions by almost 40% without affecting their health or weight.

Researchers have discovered that a seaweed-based supplement significantly reduces methane emissions from grazing beef cattle by nearly 40% without impacting their health or weight, offering a sustainable solution to one of the major contributors to global greenhouse gases.

According to a new study, giving grazing beef cattle a seaweed supplement in pellet form reduced methane emissions by almost 40 percent without impacting the animals’ health or weight. The findings are detailed in a study published December 2 in the journal Proceedings of the National Academy of Sciences (PNAS).
