What are the risks associated with heat stress in dairy cows?
- Health issues: dehydration, respiratory problems, rumen acidosis, reduced fertility
- Lower production: reduced feed intake, decreased milk yield and quality
- Weakened immunity: higher risk of mastitis, metritis, and lameness
👉 Managing heat stress is essential to protect your herd and maintain productivity.
Heat stress symptoms in dairy cattle
Heat stress in cattle can show up in many different ways. For instance, cows may stand more often than lie down. Here are some other common signs:

- Drop in milk yield
- Reduced feed intake
- Increased panting
- Immobility
- Higher water consumption
- Cooling behaviors: cows may try to get their front feet into drinking troughs or hold their dewlaps in the water to cool down
Steps to prevent heat stress with cattle

Step 1
Cooling during heat stress
Keeping your cows cool during heat stress is essential. There are three proven methods to achieve this. High-pressure cooling and cow showers quickly lower your cows' body temperature. Fans ensure pleasant air circulation and reduce heat throughout the barn. It's important to maintain consistent temperatures across the barn. These measures help protect your cows from heat stress, maintaining their health and performance.:format(webp))
Step 2
Adjusting feeding times
Consider changing your cows' feeding times to early mornings and late evenings to reduce strain on their metabolism and circulation in warmer temperatures. This schedule allows them to rest during the hottest parts of the day and keeps feed fresher longer by minimizing exposure to sunlight.Step 3
Ensuring qualitative drinking water
When cows experience heat stress, they need about 40 liters of drinking water plus an additional amount equivalent to four times their milk production. Regular checks and improvements in water quality are necessary to maintain hydration. Ensure a sufficient number of drinking stations relative to the number of animals to facilitate easy access.:format(webp))
