>... dairy farmer named Joe Dorgan inadvertently conducted an experiment on his herd in Prince Edward Island, Canada. Dorgan noticed cows that grazed on washed-up seaweed in paddocks along the shore were healthier and more productive ... and found the new diet saved him money and induced “rip-roaring heats,” or longer cycles of reproductive activity.
Thats great, but it only saved him money because it washed up right on his shore. It saves a small farmer money to let their cows graze on lush green pastures that they need to keep eaten down anyways but that doesn't mean that letting cows graze on lush pastures saves the industry money overall. In general its going to cost more more than likely to get seaweed into the supply chain. Its a race to the bottom, it has to be cheaper than subsidized corn which almost nothing is.
