Misting System
Dairy Cow and Cattle Cooling
Product Overview
High-pressure misting systems provide additional cow cooling along with ventilation. Combining micron-sized droplets with high air velocity cools the air which is being directed to the cows. Because the water droplets are so incredibly small, they evaporate before getting the cows or beds wet. High-pressure misting systems are only activated when the temperature is above 75⁰F (24⁰C) and the humidity at the exhaust end of the barn is below 80%.
Misting systems can be installed as distribution lines along curtain inlets and/or inlet fans, as distribution rings on inlet fans, or on the louvers of circulation fans. They cannot be installed on exhaust fans. Connect misting systems to a control infrastructure to automate their operation.
High-pressure misting systems help mitigate heat stress, which can increase milk production, dry matter intake, and pregnancy rates.
Adverse Effects of Heat Stress on Dairy Cows
With the temperature humidity index (THI) rising, the resulting heat stress can have a significant
impact on the health and productivity of dairy cows:
Reduced Feed Intake
Heat-stressed cows eat less for several reasons. High temperatures cause cows to experience a diminished appetite, leading to a reduction in feed intake. This thermal stress also causes animals to reduce their activity levels, further decreasing their feed intake. The result is lower milk production, ultimately impacting the profitability of dairy operations.
Decreased Milk Production
Not only do heat-stressed cows produce less milk, but that milk may also be of lower quality, with lower protein and fat content.
Increased Risk of Health Problems
When cows are exposed to high temperatures, they can become dehydrated and lose important electrolytes like sodium and potassium, which can lead to muscle weakness, fatigue, and even death. Heat-stressed cows may also experience respiratory distress, lameness, and reduced immune function, making them more vulnerable to infectious diseases.
Reduced Reproductive Performance
Cows under heat stress notably eat less and it can lead to a reduction in body weight and overall health, making it more difficult for them to conceive and maintain pregnancies. Also, high body temperatures can cause changes in hormone levels and metabolism which is linked to decreased fertility, longer calving intervals, and fewer pregnancies.
Decreased Overall Health and Performance
Heat stress can cause discomfort, dehydration, and exhaustion in cows, which can impact their overall welfare and quality of life.
High-pressure misting systems provide a safe and efficient cooling solution for barns, stables, and milking areas by lowering the temperature through ultra-fine evaporative mist.
Bonawind misting systems are suitable for various species and facility types, offering up to 15 °C (27 °F) temperature reduction without wetting the animals or bedding.
How It Works
- Water Connection: Connects to a tank or farm water line with filtration.
- High-Pressure Pump: Pressurizes water to 50–70 bar (725–1,015 psi) for effective atomization.
- Misting Nozzles: Installed above animal zones for uniform fog distribution.
- Evaporative Cooling: Ultra-fine mist evaporates quickly, cooling the surrounding air.
- Dry Surface: Bedding and animals stay dry due to instant evaporation.
- Optional Automation: Integrate with thermostats or timers for optimal efficiency.
Where Livestock Misting Systems Are Used
| Facility | Application |
|---|---|
| Dairy Barns | Reduces heat stress in high-yielding cows, improving milk production and feed intake. |
| Milking Parlors | Creates a calmer environment during milking, reducing stress and improving flow. |
| Cattle Feedlots | Improves animal welfare during summer months, reduces mortality risk from overheating. |
| Pig Houses | Regulates temperature and humidity to prevent respiratory issues and maintain growth rates. |
| Poultry Sheds | Prevents heat-related mortality and ensures better feed conversion rates. |
| Holding Pens & Corrals | Provides cooling during animal handling or transport loading phases. |
Available System Types for Livestock Facilities
| System Type | Description |
|---|---|
| Line Misting Systems | Fixed installations along beams or ceilings with evenly spaced nozzles for continuous cooling. |
| Misting Fans | Wall-mounted or mobile fans with integrated misting for targeted livestock zones or temporary pens. |
| Hybrid Solutions | Combined line and fan systems for large, open, or multi-zone livestock housing. |
