Eric Ronk is in an academic staff position in the Department of Animal and Dairy Sciences. In 2011, he received his BS in Dairy Science from the University of Wisconsin-Madison and in 2013 a MS in Dairy Science from Virginia Polytechnic Institute and State University (Virginia Tech). He grew up on a Century Farm named Ronkstar Acres, which milked 65 registered Holstein cows and harvested 240 acres of land in Denmark, WI. His work responsibilities include teaching the Introduction to Animal Sciences 101 course in the fall and summer semesters along with the Introduction to Animal Sciences Laboratory 102 course in the fall semester. In addition, he teaches the Dairy Herd Management 233 and 234 courses along with coaching the Dairy Challenge team. For over five years he taught four dairy related courses in the Farm and Industry Short Course (FISC) Program at UW-Madison. In his previous role as an outreach specialist, he was involved in dairy herd management support and research related to dairy cattle feed efficiency. In the research role he helped coordinate experiments and data/sample collection to be submitted to the Council on Dairy Cattle Breeding (CDCB). He has also been involved in some outreach activities like farm tours on campus at the Dairy Cattle Center and is currently a co-advisor to the Badger Dairy Club student organization. Prior to his UW-Madison role, Eric worked for UW-Extension as an Agriculture Agent in Calumet County.
