EXCERPT: . . . The UC Davis study will contribute to a global store of knowledge on how to limit the methane produced by “enteric fermentation” — the digestive process in a ruminant’s upper stomach chamber, or rumen, where microbes predigest fiber and starch, releasing gases when they belch and exhale. It’s “one of a handful of options in various stages of development that seem to have the potential to reduce [enteric] methane by 30 percent or more,” says Ryan McCarthy, science advisor to the Air Resources Board.
Kebreab’s experiments with seaweed additives to cattle feed have now surpassed that 30-percent figure, with one type of seaweed slashing enteric methane by more than 50 percent. In the fight to slow climate change, such reductions are no small matter: In the United States alone, domestic livestock — including cattle, sheep, goats, and buffalo — contribute 36 percent of the methane humans cause to be put into the atmosphere, according to the U.S. Environmental Protection Agency....

Except that transporting the seaweed from coastal areas to where the cattle are will produce gasses. And growing and harvesting seaweed will probably be a lot more expensive than alternative feed.
It doesn't sound practical to me.
