Identifying And Managing Heat Stress In Cattle

By Travis Meteer
 
As the temperatures and humidity elevate, it is important to understand and manage to prevent heat stress in your cattle herd. Heat stress can lower performance and in severe cases cause death. Here are some recommendations to keep heat stress at a minimum.
 
Management tips to reduce heat stress:
 
  • Ensure that water is clean and plentiful. Cattle will drink more water in times of extreme heat. Here is a chart to determine how much cattle will drink
  • Avoid handling, processing, or moving cattle. If any of these tasks need to be performed they should be done early in the morning and completed before 10am.
  • Provide shade to cattle. Shade is best if it is from trees or high clearance shades that allow a breeze to circulate underneath. Buildings or sheds are better than nothing, but they will be less allowing to airflow and air circulation. If cattle are in confinement or barns, ensure adequate ventilation and use fans to move air through and out of the building.
  • Prevent pests and other stress factors. Fly control can be beneficial to keeping animals cool. More energy and movement to control flies can have a negative relationship with cows keeping cool
  • Feed at coolest times of the day. This will help keep intake levels up and keep cattle from losing performance.
Heat stress symptoms:
  • Panting, Open mouths
  • Drooling
  • Elevated breathing rate
  • Restlessness, Extended periods of standing

The Swine Health Blackbelt Podcast, Dr. Jay Johnson from the University of Missouri explores the bioenergetics of heat stress in gestating sows and how it affects growth and fat deposition. He discusses energy partitioning, thermoregulation, and genetic strategies to improve thermal tolerance without compromising productivity. Listen now on all major platforms!

"Gestating sows under heat stress grow faster than those in thermoneutral conditions, with much of that growth going into backfat."

Meet the guest: Dr. Jay Johnson earned his Ph.D. from Iowa State University and is now an Associate Professor of Animal Welfare and Stress Physiology at the University of Missouri. His research focuses on heat stress, swine productivity, and practical welfare innovations through physiology and genomics.
