Hot weather continues across the region.
A temperature-humidity index chart can help ranchers identify when livestock are most at risk for developing heat stress. Livestock begin to experience moderate heat stress at a temperature humidity index of 82 to 83, severe heat stress at 84 to 86, and extreme heat stress at 87 or greater. A temperature-humidity index chart can be found at ndsu.ag/heat-stress.
Heat stress can significantly impact animal performance, health and welfare, making it critical to prepare a proactive management plan for unavoidable heat events. Heat stress occurs when an animal’s cumulative heat load outweighs the animal’s ability to dissipate heat, causing body temperature to rise. https://www.ag.ndsu.edu/news/newsreleases/2024/july/protect-ruminant-livestock-from-heat-stress
