Professor of aquaculture at James Cook University in Townsville, Rocky De Nys, has been working with the CSIRO studying the effects seaweed can have on cow's methane production.

They discovered adding a small amount of dried seaweed to a cow's diet can reduce the amount of methane a cow produces by up to 99 per cent.

Also this:

We have results already with whole sheep; we know that if asparagopsis is fed to sheep at 2 per cent of their diet, they produce between 50 and 70 percent less methane over a 72-day period continuously, so there is already a well-established precedent."
