Area of Expertise

John Vicini is an Animal Scientist with an emphasis in ruminant nutrition and microbiology. He has predominantly worked in areas of food and feed safety. From that research, he has helped develop methods to improve feed efficiency for livestock. In addition to his primary focus on working with dairy cattle, John also has extensive experience with beef cattle, sheep, poultry and fish. John is a Senior Research Fellow and the previous Senior Editor of Animal Nutrition for the Journal of Dairy Science, which had the highest impact factor in animal agriculture. When he’s not working with colleagues around the world to help improve global protein nutrition, you are likely to find him fly fishing… in the arctic. 

When I was in high school, I read books about feeding the planet when the world population was predicted to hit 6 billion. As we approach 8 billion now, it is interesting to reflect back to that earlier era when Paul Ehrlich wrote, ‘the battle to feed all of humanity is over. In the 1970s hundreds of millions of people will starve to death.’

Glyphosate in livestock: feed residues and animal health


In my work and research, I'm interested in improving the efficiency of food production in a safe and sustainable way. This publication considers many of the data, observations, and insights I’ve collected from the past 34 years demonstrating the safety of our products—and the need for successfully communicating our science with regulators, academic scientists, veterinarians, and consumers.
