In this episode of The Dairy Nutrition Blackbelt Podcast, Dr. Claira Seely, from the University of New Hampshire, sheds light on the evolving understanding of subclinical hypocalcemia in dairy cattle. Dr. Seely explains how the understanding of this condition has evolved over time, especially in diagnosing it at the right moment. Learn how the timing of calcium monitoring can impact milk production, reproduction, and overall cow health. Listen now on all major platforms!

"Cows with low blood calcium at four days in milk produced significantly less milk and had lower reproductive success."

Meet the guest: Dr. Claira Seely is an Assistant Professor of Precision Dairy Management at the University of New Hampshire. With a PhD in Dairy Science from Cornell University, Dr. Seely's research focuses on transition cow biology and precision technology integration.
