Where is progress up to in the development of feed additives designed to mitigate the product of methane in the rumen of beef cattle? In this week's podcast, host Kerry Lonergan chews the fat with Dr Adam Main from CH4 Australia, a company producing feed additives based on asparagopsis seaweed, farmed in a network of land-based ponds on the Eyre Peninsula. The products are already in commercial use in South Australia.

Adam also talks about the benefits and applications of farming seaweed for cattle beyond the well-worn carbon/methane debate.
