In this second part of our special Dairy Nutrition Blackbelt Podcast episode celebrating International Womenโs Day, Dr. Jennifer Van Os from the University of Wisconsin-Madison discusses the impact of air speeds on dairy cow welfare. She shares groundbreaking research on how different air speeds influence cow behavior, milk production, and overall comfort, especially in heat-stress conditions. Learn how optimizing barn ventilation can enhance dairy cattle well-being and productivity. Listen now on all major platforms!
"Fans not only reduced thermal regulatory responses but also restored lying time, which had never been documented before."
Meet the guest: Dr. Jennifer Van Os is an Assistant Professor and Extension Specialist in Animal Welfare at the University of Wisconsin-Madison. She earned her Ph.D. in Animal Behavior from UC Davis and completed postdoctoral research at the University of British Columbia. Her research focuses on understanding and improving the quality of life for dairy animals.
