After many decades of research, the dairy sector has a significant body of peer-reviewed research showing that feed additives can effectively reduce methane, the greenhouse gas that makes up most of dairy’s environmental footprint. Yet the practical use of this knowledge on farms—as well as general awareness around additive effectiveness and safety—is still gaining momentum. At this critical point in the dairy sector’s pathway to a net-zero future, the Journal of Dairy Science, the leading general dairy research journal from the American Dairy Science Association (ADSA), published by Elsevier, has released a special issue translating this nutrition innovation into detailed technical recommendations on developing and implementing feed additives. The result is a feed additive toolkit to help researchers, dairy professionals, product developers, producers, and consumers fill knowledge gaps and supercharge feed additive adoption to reduce dairy’s environmental footprint today and into the future.
