As summer approaches, we must be prepared to manage heat stress and prevent losses among our cows. Heat stress can lead to substantial losses in revenue for dairies, so it’s important to turn over every rock in looking for solutions. In this episode, with Dr. Glenn Holub, we explore the impact of heat stress during the early hot days leading up to summer, ways of identifying heat stress signals and physiological changes in cows, effective strategies and systems to minimize heat stress, and common mistakes in managing cow cooling. “If your cows start telling you that they're hot, but you don't have your cooling system up and running at peak, then it's too late.’’ - Dr. Glenn HolubWhat you’ll learn:(0:00) Highlight(1:58) Introduction (5:12) Heat stress in colder areas (10:34) Parameters for identifying heat stress in cows (12:44) Physiological changes in cows with heat stress (22:06) Management strategies for heat stress (27:52 Cross ventilation and tunnel systems (29:47) Evaporative cooling systems (32:59) The impacts of heat stress on dry cows  (38:51) The final questions Meet the guest: Dr. Glenn Holub Experience: Current: Executive Technical Service Manager at Phibro Animal Health US Inc.Past: Assistant Instructional Professor at Texas A&M University Background: Ph.D., Dairy Science (Texas A&M University)M.Sc., Dairy Science (Texas A&M University)B.Sc., Dairy Science (Texas A&M University)Connect with the guest!?????? ?? ????? ????????, ??????? ?? ??? ????? ????????.The Dairy Podcast Show is trusted and supported by innovative companies like:- AB Vista- Protekta- DSM- Diamond V- ICC- Phibro- Berg + Schmidt- Evonik- Adisseo- smaXtec
