With temperatures soaring across McDowell County this summer, heat waves can be dangerous for both people and animals—especially livestock. If you’re new to farming or ranching, knowing how to recognize and reduce heat stress in animals is critical to keeping your operation healthy and productive.
What Is Heat Stress?
Heat stress happens when animals can’t cool off fast enough. You might notice signs like:
-
Heavy breathing or open-mouth panting
-
Drooling or foam around the mouth
-
Lethargy or stumbling
-
Bunching in the shade (or around water)
If not addressed quickly, heat stress can lead to serious illness or even death.
5 Simple Ways to Protect Your Animals
1. Always Provide Cool, Clean Water
Livestock drink twice as much during hot days. Check troughs often and refill them regularly. Keep them in the shade if possible.
2. Give Them Shade
Natural trees or simple tarp structures can drop body temps by several degrees. Shade reduces direct sun exposure and gives animals a place to rest.
3. Avoid Midday Handling
Plan chores like feeding, vaccinations, or moving animals in the early morning or evening, when it’s cooler.
4. Improve Airflow
Open barns or pens to natural breezes. If animals are indoors, use fans for circulation. Good airflow helps animals release heat.
5. Watch Closely
Check animals at least twice a day during a heat wave. Separate and cool off any that seem weak or are breathing heavily.
Bonus Tips
-
Use misters or sprinklers to cool animals, but be sure there’s airflow so they dry off. Wet + no wind = more humidity = more heat stress.
-
For pigs and some poultry, consider shallow mud or water wallows to help them cool naturally.
-
Keep pens clean and avoid overcrowding—more space means better cooling.

Stay cool out there—and so will your animals!
