Managing Seasonal and Daily Rhythms to Maximize Milk Components
There are strong seasonal and daily patterns to milk yield and composition. Although the rhythms are rather robust, lighting and feeding times have an impact on these rhythms and provide an opportunity to increase milk component yields. We will discuss what we know about these rhythms and highlight opportunities to better manage them.

Speakers

Dr. Kevin Harvatine
@Penn State University
Kevin J. Harvatine is Professor of Nutritional Physiology at Penn State University. He grew up on his family’s dairy farm in Pennsylvania and received his BS in Animal Science from Penn State. He earned an MS from Michigan State University and PhD from Cornell University. Dr. Harvatine’s research is focused on the nutritional regulation of milk synthesis. His goal is to identify nutritional, environmental, and physiological factors that impact milk synthesis and develop strategies to improve animal production, efficiency, and health. His research spans from applied nutrition to basic biology and provides both real-world applications to the dairy industry and a basic understanding of biological mechanisms. Current ongoing projects focus on seasonal and circadian rhythms of mammary metabolism, effect of acetate and specific long-chain fatty acids on mammary lipogenesis, omega-3 fatty acid metabolism, and impact of rumination on milk fat depression.
