Eric Ronk is in an academic staff position as an Assistant Faculty Associate 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 at the undergraduate level and 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.

Farm and Industry Shortcourse Courses:
FISC 63 – Dairy Herd Management (2 credits, Fall)
Course Description: Students will learn how to care for their dairy herd to increase production and profits. Use of business and herd management tools in dairy farm operations will be covered in depth. Case studies of individual farms used for analysis and planning. Specific topics covered will include: record keeping, cattle movement and behavior, parlor management, milk harvest, mammary anatomy, mastitis and milk quality control, cattle comfort and housing options, herd culling decisions, and interacting with the consumer.
FISC 105 – Dairy Cattle Selection and Evaluation (2 credits, Spring)
Course Description: Covers basic anatomy, genetics, and linear scoring systems of a dairy cow. Students evaluate conformation using type scorecards to improve the appearance, performance and longevity of dairy cattle. North American dairy breeds and mating programs are studied.
FISC 114 – Ruminant Nutrition (2 credits, Spring)
Course Description: Students will learn practical nutrition for lactating dairy cows, dairy heifers, and dairy beef. Students will learn the basic anatomy and physiology of the digestive system of ruminant animals and how feeding and management are geared toward optimizing rumen function. This course will introduce the basic concepts of nutrition and how feeds provide nutrients and basic skills necessary for feeding dairy cattle.
FISC 134 – Reproduction in Farm Animals (2 credits, Spring)
Course Description: Students will learn the basic comparative physiology of reproduction of farm animals and apply those physiological principles to understand successful heat detection, artificial insemination, estrous synchronization, embryo transfer, pregnancy diagnosis, and improvement of reproductive efficiency through good reproductive management.
An Sci/Dy Sci 101 – Introduction to Animal Sciences 101 (4 credits, fall)
Course Description: Anatomy and physiology, nutrition, genetics, reproduction, marketing, meats and management of dairy and beef cattle, swine, sheep, poultry, and horses; lectures, laboratories, and discussion.
