Serotonin and Calcium homeostasis during the transition period

Dr. Laura L. Hernandez is an Associate Professor in the Dairy Science Department at the University of Wisconsin-Madison.  Her area of research has focused on how serotonin controls the mammary gland and various aspects of lactation.   She specifically focuses on the interaction of serotonin and calcium metabolism during the transition period.  Her research has determined that serotonin is an important regulator of mammary gland and maternal calcium homeostasis during lactation. Dr hernandez kicks off the transition unit of our webinars this year.

Supplemental fatty acids in lactating cow diets: myth and reality

Dr. Adam Lock is an associate professor in the Department of Animal Science at Michigan State University. Originally from a dairy farm in the southwest of the United Kingdom, Dr. Lock received his PhD from the University of Nottingham and completed a post-doc at that institution as well as at Cornell University. His research and extension programs focus on both dairy production and human nutrition and health, and the interface between these two disciplines. Current efforts concern the effect of diet on the production of biohydrogenation intermediates in the rumen, dietary strategies for maximizing milk fat synthesis, applying this knowledge to improve our ability to troubleshoot on farm issues related to milk fat depression, fatty acid absorption in the small intestine, fat supplementation opportunities, and the potential for omega-3 fatty acids to promote dairy cattle metabolism and health.
