Dr. Paul Kononoff
University of Nebraska-Lincoln
Dr. Paul Kononoff is an Associate Professor of Dairy Nutrition in the department of Animal Science at the University of Nebraska-Lincoln. His research focuses on feed characterization and the relationships between fiber quality and ruminal fermentation in lactating dairy cattle. He has studied how manipulations of forage particle size and cell wall lignification affects feed efficiency, milk production, milk composition, and rumen fermentation. His research has also examined ration formulation methods that seek to maximize the inclusion of corn milling co-products while sustaining normal milk production and composition. As a dairy nutritionist, Dr. Kononoff has assisted the dairy industry as a Technical Support Specialist for Renaissance Nutrition (Roaring Spring, Pennsylvania) and as a Project Director of the Ruminant Feed Analysis Consortium (Durham, NH). Dr. Kononoff is a member of the American Dairy Science Association and the Nebraska State Dairy Association. He served as an editor for the Journal of Dairy Science and the Canadian Journal of Animal Science. He received his B.S. and M.S. in Animal Science from the University of Saskatchewan and Ph.D. in Animal Science from Pennsylvania State University.
Dr. Helene Lapierre
Dr. Hélène Lapierre is a Research Scientist of Animal Metabolism in the Dairy and Swine Research and Development Centre at Agriculture and Agri-Food Canada and an Adjunct Professor in the Department of Animal Science at Université Laval. Her areas of expertise include the efficiency of nutrient use in the production of milk and milk components, factors affecting release or utilization of nutrients by the gut, the liver and the mammary gland, and improvement of the transfer of protein from dairy rations into milk protein in order to lower milk production costs and reducing nitrogenous excreta in the environment. Dr. Lapierre is a member of the Canadian Society of Animal Science and the American Dairy Science Association. She was the recipient of the CSAS Award in Excellence in Nutrition and Meat Science in 2014 from the Canadian Society of Animal Science. Dr. Lapierre earned her B.S. and M.S. in Agriculture from the Université Laval, and Ph.D. in Biology from the University of Sherbrooke. She conducted post-doctoral work at the USDA Agricultural Research Service.
Dr. Michael VandeHaar
Michigan State University
Dr. Michael VandeHaar is a Professor of Dairy Nutrition and Physiology in the Department of Animal Science at Michigan State University. His research involves dairy cattle nutrition and physiology with the intent of improving heifer growth and mammary development and increasing the efficiency of protein production in the dairy industry. For the past 4 years, Dr. VandeHaar has been project director of a large USDA-funded project, “Genomic Selection and Herd Management for Improved Feed Efficiency of the Dairy Industry.” A major part of the project is to develop a database of feed intake and milk output on 8000 cows with genotypes. This database will be used to develop genomic breeding values for feed efficiency and to develop and test nutritional models. Dr. VandeHaar is a member of the National Animal Nutrition Program NRSP-9 modeling subcommittee. In 2013, he was awarded the highest honor for dairy scientists in nutrition, the American Feed Industry Association Award. Dr. VandeHaar earned his B.A. degree from Dordt College, Iowa, and M.S. and Ph.D. from Iowa State University. He conducted his post-doctoral work at the University of North Carolina.
