The viability of feeding seaweed to cows. An assessment of the key opportunities and barriers facing the commercialization of factory-produced Asparagopsis taxiformis as a methane-reducing additive for dairy cows in Sweden.
An estimated 6% of human greenhouse gas emissions are the result of enteric methane production by cows. Asparagopsis taxiformis, a semi-tropical alga, is one solution. Supplementation of this alga to cows at a small percentage of their daily intake has reduced methane emissions by over 98% in trials. This success has led to multiple commercialization attempts globally, although no Asparagopsis tax
