Managing heat stress in dairy cows
Based in the Aveyron region of France, GAEC du Rosier Blanc farms around 100 dairy cows across 90 hectares. With heatwaves becoming more frequent, the farmers chose to improve barn comfort with a ventilation solution: Cyclone 360.
Very quickly, the farmers noticed changes in the animals’ behaviour. The cows spent more time inside the barn, benefiting from the airflow generated by the fans. They continued to eat and drink normally. As a result, milk production remained stable despite the prolonged heatwave.
Animal comfort improves significantly on a daily basis. The cows lie down more easily and use the stalls more frequently. The Farmers also notice the difference, thanks to the constant airflow generated by the fans. This improved comfort also translates into strong reproductive performance. Artificial insemination results remain satisfactory, even during periods that are typically more challenging.
At first, the farmers questioned the value of installing fans in a building that was already well aerated. This feedback highlights a key difference between an aerated building and a ventilated one. A building may be well aerated, but that is not always enough to mitigate the effects of heat.
A building can be well aerated, but that’s not enough. Ventilation makes all the difference.
In hot weather, an aerated building renews the air, but it remains warm. The animals still feel the heat. With Cyclone 360, air is circulated at sufficient speed. This direct airflow promotes evaporation and helps the animals dissipate heat more effectively. The perceived temperature actually decreases.
"When we ventilate, air begins to circulate… helping cows feel more comfortable through its effects on their skin."
Looking back, the conclusion is clear. Cyclone 360 improves animal comfort and safeguards farm performance during hot periods.
This testimonial highlights the importance of proper ventilation in helping farms adapt to changing climate conditions.
