“Best Management Practices for Optimal Animal Welfare During the Transition Period”
Presenter: Adrian Barragan, Associate Research Professor and Extension Veterinarian, Pennsylvania State UniversityThe transition period is the most challenging time during the dairy cow’s production cycle. Proactive best management practices must be in place to prevent diseases and maintain the optimal welfare of cows. During this presentation, Dr. Barragan will cover research-based practical information regarding managing dairy cows during the transition period with a focus on preventing diseases and improving animal welfare.

“The Science and Art of Milking”
Presenter: Dr. Paula Ospina, Owner, Urgent Veterinary Care
Milking is the most important 15 minutes (3x) of a cow’s life and serves as a great opportunity not only to complete the milking process but also to evaluate the herd’s health, resulting in better milk quality. In this talk, we will address topics on how to explain and motivate workers about the purpose of each step and the importance of following milking procedures.

“Multigenerational Effects of Heat Stress in Dairy Cows”
Presenter: Jimena Laporta Sanchis, Associate Professor, Lactation Physiology, University of Wisconsin – Madison
Heat stress during the dry period (last 6–8 weeks of gestation) represents a significant threat to the health, well-being, and productivity of dairy cows. This period is critical not only for the cow but also for fetal development, especially for key organs such as the immune, digestive, and mammary gland systems. Our studies have shown that the effects of maternal heat stress are not limited to the exposed generation (F0) but also impact the offspring exposed in utero (F1) and even the subsequent generation (F2), including lasting changes in growth, physiology, mammary development, and milk productivity. This presentation will focus on the characterization of these multigenerational effects. In addition, we will address the impact of pre-weaning heat stress on calves and discuss novel mitigation methods to improve calf welfare, thermoregulation, and performance in hot environments.
