Animal scientist Joseph McFadden researches the interactions between nutrition, environment and food animal production. He’s also leading the development of four respiration chambers that measure complete gas exchange to help quantify greenhouse emissions from an animal through the testing of feed ingredients, additives and drugs. It’s only with this holistic approach, McFadden believes, that we can provide transparency while simultaneously accelerating the approval of effective dietary approaches – by reducing methane emissions in the short-term, and by reducing CO2 as a longer-term climate goal. Farms of the future will also need to focus on global solutions. “I’m optimistic that we’ll have dietary approaches to suppress methanogenesis without compromising efficiency. What’s going to be more challenging is identifying solutions to enhance efficiency in underdeveloped countries. Every region is going to require a unique solution,” he said. “Now is the time for us to use our training for the betterment of society.”
