A Clearer Picture: Using Ultrasound to Detect Respiratory Issues in Calves

TOPIC: Animal Welfare

Dr. Theresa Ollivett, Associate Professor at the University of Wisconsin–Madison School of Veterinary Medicine, will dive into the hidden challenges of respiratory disease in young dairy calves. On-farm lung ultrasounds reveal that pneumonia often lurks beneath the surface—even after treatment—impacting calf growth, welfare, and profitability. In this session, Dr. Ollivett will discuss the critical questions producers and veterinarians should be asking and demonstrate how lung ultrasound can provide answers. She’ll share practical applications for identifying risk factors, detecting problems early, monitoring treatment effectiveness, and tracking disease trends to improve herd health and performance.

Virtual Fence Meets Pasture Nutrition for Maximum Productivity

TOPIC: Nutrition

Well‑managed pastures can deliver highly digestible, protein‑rich forage. Pasture alone rarely provides a perfectly balanced diet, especially for high‑producing dairy cows. What you choose to supplement with can dramatically influence milk yield, components, body condition, and even reproductive performance. Supplementation isn’t just “extra feed”-it’s how you correct the nutritional gaps that pasture creates.
