Animals and heat stress


This week in northern Nevada we are expected to reach 100+ degrees (Fahrenheit), luckily our humidity is low at 5-12%. This type of dry heat can be a serious problem for livestock. Also very problematic is high heat and high humidity areas of the country. With the humidity, the animals’ core temperatures takes longer to cool as the night time temperatures occur much later in the evening, if at all.

It is essential to ensure all animals (and humans) have access to plenty of clean, cool water. If possible, they need a place to get out of the sun, whether that be a shed/building or trees. Also, make sure any airflow will get to them, blocking wind or even a breeze can greatly increase their discomfort. Providing a water mist may be helpful and cooling to animals, however, droplet size is key! Large droplet sizes are best. Finally, if you must move or work livestock during these high temperature events try to do it early in the morning or in the evening when the temperatures start to cool down.
