In 1991, Dr. Mike Hutjens, emeritus professor in the Department of Animal Sciences at the University of Illinois, defined four key factors for evaluating feed additives: Response, Returns, Research and Results (Hutjens, 1991). Dr. Hutjens later added 3 additional Rs for industry professionals to consider: Repeatability, Reliability and Relativity. Feed additives that claim to reduce methane emissions from cattle will emerge as potential tools to mitigate climate change. The pressure to consider their use will be significant. However, we must consider these seven Rs when evaluating the efficacy, economics and safety of feed additives to inhibit enteric methane emissions from cattle without impacting animal performance, farm profitability or consumer acceptance of the technology.
I grew up in Wisconsin and as a child, vacation meant going to my grandparents’ dairy farm in Prairie du Chien to help bale (really stack) hay or feed calves. The summer after my freshman year of college, I woke up at 4:30 a.m. to drive 30 minutes to work on a dairy farm – for free! So, my love for dairy farms, dairy cows and milk, cheese and ice cream runs deep. When I saw the article, “Removal of dairy cows may reduce essential nutrient supply with little effect on greenhouse gas emission,” I knew I had to read it.
