In this episode of The Dairy Health Blackbelt Podcast, Bridger Sparks, PhD candidate at Texas Tech University, explains how adipose tissue innervation influences lipid mobilization and metabolic health in dairy cows. He discusses parity effects, catecholamine regulation, and links to ketosis and transition disorders. Bridger highlights future strategies for breeding and biomarker development. Listen now on all major platforms!

"Excessive lipid mobilization creates significant metabolic stress, increasing the likelihood of disorders that impact productivity, reproduction, and overall efficiency within modern dairy systems."

Meet the guest: Bridger Sparks is a PhD candidate in Animal Science at Texas Tech University, focusing on how adipose tissue innervation affects metabolic health in dairy cows. His work integrates neurobiology and physiology to study transition period challenges, with publications in the Journal of Dairy Science and recognition from ADSA.

In this part two episode of The Dairy Health Blackbelt Podcast, Dr. Amanda Fischer-Tlustos, NSERC postdoctoral research fellow at UC Davis and the University of Guelph, continues the conversation, explaining how dry off strategies and dry period length influence colostrum quality and IgG transfer. She discusses regenerative involution, high milk production at dry-off, and management approaches to improve colostrum outcomes. Listen now on all major platforms!

“The length of the dry period has been repeatedly associated with colostrum production, particularly when cows are managed appropriately before calving.”

Meet the guest: Dr. Amanda Fischer-Tlustos is an NSERC postdoctoral research fellow at UC Davis and the University of Guelph, specializing in whole body and mammary metabolism. She completed her MSc at the University of Alberta, studying colostrum management, and her PhD at the University of Guelph, focusing on maternal and mammary factors affecting colostrum production and composition.

In this part one episode of The Dairy Health Blackbelt Podcast, Dr. Amanda Fischer-Tlustos, NSERC postdoctoral research fellow at UC Davis and the University of Guelph, explains how colostrum is produced and what drives its composition. She shares new findings on IgG accumulation, macronutrient synthesis, mammary activity during the dry period, and management factors influencing colostrum quality. Discover practical insights to improve dairy health outcomes. Listen now on all major platforms!

“Higher milk yield at dry off was linked to greater mammary activity during the dry period and poorer colostrum outcomes.”
