HVLS Fans for Dairy & Livestock Barns
In livestock farming, protecting animals from heat is often more important than protecting them from cold. Cattle naturally run a higher body temperature than people — roughly 101–102°F (38.5–39.1°C) — so when the barn gets warm and humid, they feel it fast. Once ambient conditions climb past about 75–80°F (24–27°C), many cattle begin to experience heat stress, and that quietly eats into a farm’s productivity all summer long.
Why Heat Stress Hurts Your Herd
When cattle are heat-stressed, you’ll often see faster breathing, raised body temperature, more sweating, less movement, and reduced feed intake. Over time this can lower milk yield, slow weight gain, and affect reproduction and overall immunity. Industry research consistently links good barn airflow to calmer, more comfortable, more productive animals.
How HVLS Fans Help
When natural wind is weak or missing, a high-volume, low-speed (HVLS) fan moves a large, gentle column of air across the whole barn. That steady airflow helps cool animals, improves ventilation, and helps keep bedding and deep-litter areas drier — which can reduce the moisture conditions linked to hoof, leg, and udder problems. Because HVLS fans move a lot of air slowly and quietly, they cover large open barns without the noise or harsh blast of small high-speed fans.
