How to Keep Livestock Cool in Hot Weather

Sheep Hot WeatherDuring the summer months when high temperatures and humidity combine, keeping your livestock cool and comfortable is an absolute necessity. How to keep animals cool in hot weather should be a priority. Otherwise, many can succumb to heat-related stress, exhaustion, stroke—and unfortunately, death. Enclosed spaces without proper ventilation will result in serious problems for you, your animals, and your farm.

How Hot is Too Hot for Livestock Animals?

Maintaining productive livestock environments for cattle, sheep, horses, pigs, goats, chickens, and other animals during a heatwave is not too difficult, but it does take advanced planning. Once temperatures settle in at or above 80 degrees Fahrenheit (27 C), it’s time to implement that plan, which in large part depends upon your livestock. It may be easy to spot a horse affected by heat—horses have sweat glands and actually perspire. However, cows, pigs, sheep, and goats do not have sweat glands. Cows and pigs are very heat sensitive animals, whereas, goats and sheep are exceptionally heat-tolerant animals. A cow’s mouth will hang open and its snout will become moist when it’s overheated. Chickens will spread their wings and open their beaks to seemingly gasp for air. Pig temperature requirements are important in optimizing their growth efficiency. Amazingly, sheep’s wool protects them from extreme heat or cold.

Despite the degrees of tolerance for each animal, common signs of heat stress among livestock include:

  • Lethargy
  • Loss of appetite
  • Trembling
  • Confusion or disorientation

Treating Livestock Heat Stress

Once the above symptoms become visible or apparent there are several steps that can be taken to aid your animals.


Goats Drinking WaterThough it is common sense, the first action should be to provide fresh, clean, cooled water—even gently hose the animals down with a fine spray or mist. Supplying cool, clean drinking water is necessary for keeping livestock no matter what the temperature is, but is a must in extreme heat. Have watering troughs in the shade, or add automatic watering fountain systems that replenish the trough with fresh cool water several times a day.


Make sure the animals are moved into a shaded area or are housed. Animals up to pasture should have ample shade. Trees throughout the pasture, or ideally, forested areas for your animals, can be much cooler than a barn. However, as many pasture lands are lacking in widespread areas of shade, keeping the barn or other farm buildings well ventilated is essential for productive environments.


Because livestock will spend so much time in the barn, buildings should be properly ventilated. A proper barn ventilation system to keep animals cool and comfortable during the most oppressive heat waves.
