Heat stress is a significant and ongoing problem for poultry farmers in South Africa, especially with global temperatures on the rise. Heat stress occurs when chickens are unable to balance their internal heat production with their body heat loss, particularly in high temperatures. This can lead to reduced feed consumption in broiler chickens by 5% for every 1°C increase in temperature between the temperatures of 32°C and 38°C. And within just one month, heat stress can decrease the egg production of laying hens by 26.4%. Fortunately, misting systems can cool the surrounding environment down by up to 10% – reducing chicken heat stress and related side effects.
Heat stress can have various detrimental effects on your chickens, including:
- Heat stress reduces feed intake, slowing chicken growth and production.
- Egg production decreases, with thinner shells and increased breakage rates.
- It impacts the texture and consistency of the meat, leading to a drop in meat quality.
- Chickens may start to show signs of stress and fatigue, affecting the health of the flock.
- Heat stress causes inflammation in their small intestines.
- It weakens chickens’ immune systems, making them more vulnerable to other diseases.
- Prolonged exposure to heat stress increases chicken mortality, leading to financial loss.
How High-Pressure Misting Systems Can Prevent Heat Stress in Chickens
High-pressure misting systems can cool your chickens down by up to 10%, keeping them at the optimal temperatures to prevent heat stress. These systems are made up of a high-pressure pump, tubing, and specialised nozzles that spray ultra-fine water droplets into the air. When these water droplets come into contact with the warm air they evaporate almost instantly, creating a rapid cooling effect without leaving surfaces wet. This makes high-pressure misting systems ideal for use in chicken houses, as wet chickens are susceptible to a whole other host of illnesses.
The Benefits of High-Pressure Misting Systems in Poultry Farming
In addition to keeping your chickens cool, high-pressure misting systems can have various advantages for poultry farmers:
1. Reducing Heat Stress and Chicken Mortality
Most chicken houses in South Africa are built from metal zinc sheets, which absorbs and retains heat, making them very hot inside. This build-up of heat can cause severe dehydration, exhaustion, and even death in your chickens. High-pressure misting systems can rapidly cool the air inside your poultry houses, significantly lowering the risk of heat stress and chicken mortality.
2. Sanitising Chicken Houses
Additionally, misting systems can be used to distribute sanitising agents and medications evenly over the chickens’ enclosures. This helps to maintain a clean, bacteria free environment where your chickens are less likely to get sick.
3. Improving Air Quality and Odours in Poultry Houses
High-pressure misting systems create an ultra-fine mist, which binds with airborne dust and other particles, pulling them out of the air. This not only reduces the amount of dust in your chicken houses, but can also eliminate unpleasant odours, creating a cleaner environment that reduces respiratory illnesses for your chickens.
4. Reducing Pests on Poultry Farms
Lastly, these misting systems can be used to repel flies and other insects. By dispersing water or insecticides, you can repel flying insects around your chickens. This helps to keep your chickens clean and healthy.
With heat stress remaining a significant and ongoing problem for chicken farmers in South Africa, now is the time to invest in a high-pressure misting system. Ready to protect your chickens and improve your farm’s productivity? Contact MaPa Cleaning Technologies today!
