Water mist on cow farms – an effective solution against heat stress
Studies have shown that at temperatures above 26°C, dairy cows begin to reduce feed intake, lose weight and experience severe heat stress. This directly affects animal welfare, milk production and milk quality.
Highly productive dairy cows are particularly sensitive to high temperatures , where even short periods of heat can lead to significant economic losses for the farm.
What is heat stress in cows
The degree of heat stress depends on a combination of factors, not just air temperature. The most important of these are:
- ambient temperature
- relative humidity
- air circulation
- direct sunshine
Many farmers use fans and large amounts of water for cooling, but in most cases this is not enough, especially in high summer temperatures.
High-pressure water mist in cow farms and milking parlours
One of the most effective solutions against heat stress is a high pressure water mist system combined with forced ventilation.
This method provides:
- a significant decrease in the temperature in the barn
- optimal microclimate without wetting the animals
- a more relaxed and comfortable environment for the cows
The system works by spraying water through micron noozles at a pressure of about 70 bar generated by a high-pressure piston pump.
How the water mist system works
At high pressure , the water turns into micro droplets that form a fine mist. On contact with the hot air , an instantaneous heat exchange (cold steam/warm air) takes place .
The result is:
- rapid temperature reduction
- without wetting the floor or animals
- maintaining a stable and pleasant room climate
The temperature in the barn can be reduced by a few degrees, which is quite sufficient to avoid heat stress.
Additional advantages for livestock farms
High-pressure water mist not only cools, but has a number of additional benefits for cow farms:
- reduces dust and volatile particles
- refreshes the air
- neutralizes unpleasant odors, such as ammonia
- repels flies and flying insects
- improves hygiene in milking parlours
Creating an environment with higher humidity, but without wetting, makes the room unattractive to insects, resulting in calmer animals and an easier milking process.
Air disinfection and control in cow farms
Another major advantage of water mist systems is the ability to disinfect the animal housing.
Through integrated:
- dosing pump
- programmer for time and cycles
disinfecting solutions can be added directly into the mist. This provides a controlled and effective air treat without stress to the animals.
Main benefits of water mist in cow farms
The use of a water mist system in milking parlours, barns and milking robots leads to:
- reducing heat stress
- lower temperature and better comfort
- fewer flies and insects
- cleaner air and less dust
- better hygiene and disinfection
- optimising milk production
Conclusion
Water mist is a proven effective solution for cooling and improving conditions on cow farms. Through a combination of cooling, insect control and disinfection capability, water mist systems significantly improve animal welfare and farm profitability.
