Guests:Dr. Geoff Dahl, University of FloridaDr. Jimena Laporta, University of Wisconsin-MadisonWe 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.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. 4:44To 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. 8:40Dr. Laporta discusses the stress can continue into future lactation periods of both the dam and the offspring. 16:45Both researchers highlight their opinion on cow longevity in the herd and how stress can change the length of the cows’ time in the herd. 22:48While the Florida humidity heightens the stress Dr. Dahl sees in Florida; both researchers highlighted they see seasonal effects on cows everywhere. If lactating cows are under stress for even a week, Dr. Laporta discusses the short-term event will have a long-term impact on the cow. 35:54Heat stress can also cause acceleration of the maturation process for gestation timing. Dr. Dahl discusses the calf is signaling it is ready to be born based on the increase in the cows’ internal temperature. 45:09If you want one of our new Real Science Exchange t-shirts, make sure to screenshot your rating, review or subscription, and email a picture to anh.marketing@balchem.com. Include your size and mailing address and we’ll get a shirt in the mail to you.Please subscribe and share with your dairy industry friends to bring more into the conversation around the Real Science Exchange virtual pub table.This podcast is sponsored by Balchem Animal Nutrition and Health.
