Seaweed Can Reduce Methane From Cows, But….

By now, you've probably heard the news that supplementing cattle with seaweed could reduce methane belched by livestock. In fact, researchers in Australia and the U.S. have found that feeding as little as .5% "Asparagopsis taxiformis, a red seaweed that grows in the tropics, can decrease methane emissions by 80 percent or more. But there are still unresolved challenges to this solution, the first being finding enough seaweed. Alexander Hristov, distinguished professor of dairy nutrition at Penn State, says that to get enough seaweed to make a difference globally, the scale of production would have to be immense. With nearly 1.5 billion head of cattle in the world, harvesting enough wild seaweed to add to their feed would be impossible. Even to provide it as a supplement to most of the United States' 94 million cattle is unrealistic. "To be used as a feed additive on a large scale, the seaweed would have to be cultivated in aquaculture o

I would like to find any federal BLM permittees (especially on more arid lands) who have managed to apply planned rotational grazing practices on their allotments in such a way as to certifiably improve ground cover and watershed function. I would like to promote any successful examples of good practice. Thanks

  3. Could mixing seaweed into molasses or some kind of supplement tubs get pastured livestock to eat it?
