We are back at the Real Science Exchange and invite you to pull up a chair and join us to discuss the effects of heat stress on late gestation cows. Tonight’s guests, who have worked together on research in this area, Dr. Geoff Dahl with the University of Florida and Dr. Jimena Laporta with the University of Wisconsin-Madison, join Scott Sorrell and Dr. Clay Zimmerman.

Season 3, Episode 21

 

Guests:

Dr. Geoff Dahl, University of Florida

Dr. Jimena Laporta, University of Wisconsin-Madison

 

Here is a breakdown of the episode:

  • Dr. Dahl kicks off the discussion by level setting with the idea that cows have a thermal comfort zone and that it’s not just temperature but also humidity that can stress a cow. 4:44
  • To get a more accurate stress reading, Dr. Laporta and Dr. Dahl’s research has focused on measuring stress and environmental indicators without getting in contact with the animal. 8:40
  • Dr. Laporta discusses the stress can continue into future lactation periods of both the dam and the offspring. 16:45

To hear the full episode, visit BalchemANH.com/podcast or search for “Real Science Exchange” on your favorite podcast platform. In the complete episode you’ll hear more from both researchers including their insights on cow longevity in the herd and how stress can change the length of the cows’ time in the herd; what happens if lactating cows are under stress for even a week and how heat stress can cause acceleration of the maturation process for gestation timing.
