Did you know that India accounts for about one-third of the world’s one billion head of cattle? Last week on Sea Change Radio, we spoke to the head of Rumin8, a startup that’s working to reduce methane emissions from cattle. This week, we take a more academic approach to the cow burp problem – our guest is Dr. Joseph McFadden, a professor of cattle biology at Cornell University. We learn more about the science of enteric fermentation in ruminants, examine the various technological solutions aiming to reduce these methane emissions, and discuss the hurdles that the feed additive industry faces, and why they are particularly challenging in countries like India.
