4-State Dairy Nutrition & Management Conference

SPEAKERS

	Dr. Adrian A. Barragan Dr. Adrian A. Barragan is an Extension Veterinarian and Assistant Clinical Professor within the Veterinary and Biomedical Science Department in the College of Agricultural Sciences at the Pennsylvania State University. Dr. Barragan is originally from Algarrobo, Buenos Aires, Argentina. He completed his DVM in 2010 at the University of La Plata, Argentina. After graduating from vet school, he practiced as a beef cattle veterinarian on feedlot facilities in Argentina before moving to Colorado, where he worked as a veterinarian and researcher on a large organic dairy farm. Afterwards, he pursued graduate training at The Ohio State University, where he obtained his Master and PhD degrees. Dr. Barragan is involved in extension and outreach activities and field investigations, as well as developing and performing applied research to help dairy producers. His research interests have been related to developing new disease preventive practices to improve cow welfare and fertility and developing better training and management programs for Spanish-speaking farm employees in dairy operations.
	Dr. Phil Cardoso Dr. Phil Cardoso is an associate professor at the University of Illinois at Urbana-Champaign. He received his D.V.M., and M.S. degrees from the Federal University of Rio Grande do Sul in Brazil and his Ph.D. from the University of Illinois. Since 2012, Phil has established a unique program and online presence that seamlessly blends his teaching, extension, and research efforts. Phil's Dairy Science program impact by placing students in applied positions and academia. Phil and his students have published over 80 peer-reviewed manuscripts (original research and invited reviews) and 3 invited book chapters to date. The program builds from questions from dairy producers and focuses on having the dairy cow's diet as a medical prescription for performance, health, and reproduction. That is achieved by understanding the impact of nutrition on metabolism, reproduction, and health in dairy cows, as well as mechanisms of metabolic adaptation to stressors and forage quality.
	Dr. Luiz Ferraretto Dr. Luiz Ferraretto is a Ruminant Nutrition Extension Specialist in the Department of Animal and Dairy Sciences at University of Wisconsin-Madison, and his research interests are applied dairy cattle nutrition and management with emphasis on starch and fiber utilization by dairy cows, forage quality and digestibility, and the development and evaluation of assays for feed and forage analysis.
	Isaac Haagen Isaac Haagen is an Assistant Professor of Dairy Production in the Department of Animal Science at the University of Minnesota. Prior to joining the University of Minnesota in 2023, Dr. Haagen completed a PhD at Penn State University and a postdoc at the USDA National Animal Germplasm Program. During his PhD, Dr. Haagen focused on the genetics of dairy youngstock disease resistance and wellbeing. Dr. Haagen is currently conducting research relating to breeding and management strategies that can improve dairy youngstock well-being and efficiency.
	Patrick C. Hoffman Patrick C. Hoffman is Professor Emeritus at the University of Wisconsin-Madison. He received his B.S. degree from the University of Wisconsin-Platteville and his M.S. degree in Dairy Science from the University of Wisconsin-Madison. Previously, he was employed at the University of Wisconsin for 34 years serving as the Outreach Program Manager for the Dairy Science Department at the Integrated Dairy Research Facility located at the Marshfield Agricultural Research Station. Professor Hoffman is the author of over 225 scientific manuscripts and abstracts and received numerous awards for his dairy research program. Professor Hoffman also served for 7 years as a Dairy Technical Specialist for Vita Plus Corp., Madison, WI and is currently the owner and senior consultant at Dairy Science Solutions, LLC.
	Dr. Sabine Mann Sabine Mann is an Assistant Professor of Ambulatory Medicine. She received her DVM degree from Hannover, Germany, her veterinary doctorate from LMU Munich, Germany, and her PhD from Cornell University in transition cow nutrition and physiology and epidemiology. Her current research focuses on the intersection of metabolism, nutrition, and immunology. She is particularly interested in nutritional strategies and interventions to improve host resilience in newborn calves and postpartum cows.
	Dr. Jess McArt Dr. Jess McArt is an Associate Professor of Ambulatory and Production Medicine at Cornell University’s College of Veterinary Medicine. A diplomate in the American Board of Veterinary Practitioners (Dairy Practice), Dr. McArt performs clinical service for the Ambulatory and Production Medicine Clinic, teaches veterinary students both in the classroom and on farms, and conducts applied research. Her research program focuses on the identification, epidemiology, and economics of periparturient metabolic diseases in dairy cows.
	Dr. Eduardo de Souza Ribeiro Department of Animal Biosciences, University of Guelph Dr. Eduardo Ribeiro grew up on a small family farm in southern Brazil and graduated in Veterinary Medicine at the Santa Catarina State University in 2008. In 2009, he moved to Florida to start his graduate studies in the Department of Animal Sciences at the University of Florida, completing a MSc in 2011 and a PhD in 2015. In 2016, Dr. Ribeiro joined the Department of Animal Biosciences at the University of Guelph as an Assistant Professor, and in 2020 he was promoted to Associate Professor. At Guelph, Dr. Ribeiro teaches animal health and animal reproduction to undergraduate and graduate students and leads a research program in reproductive health of dairy cattle. His multidisciplinary research program examines problems related to transition health and fertility of dairy cows at all levels of organization, from herd management to cell biology, and aims to develop novel management solutions that ultimately improve efficiency and sustainability of dairy production.
	Dr. Normand St-Pierre Dr. St-Pierre is Professor Emeritus at The Ohio State University and currently President of the American Dairy Science Association. He grew up in Québec, Canada, and received his Ph.D. degree in Dairy Science from The Ohio State University with minors in statistics and economics. He spent most of his career at Ohio State, where he conducted research and extension programs in farm management, nutrition, and biometrics until his retirement from the university in 2016. Before professionally retiring, Dr. St-Pierre oversaw the R&D and Technical Services department for Perdue AgriBusiness - Animal Nutrition until Fall 2022. Dr. St-Pierre has published over 700 articles and has received numerous awards for his work. Now that he is happily retired, you likely will find him riding one of his 12 bicycles or daydreaming on his beloved sailboat with plans to sail far away from civilization.
