In summer, maintaining the health and productivity of broiler chickens requires careful management. Here are three key strategies to help keep them comfortable and thriving.
**First, implement the "three down" measures:**
1. **Cooling**: Chickens lack sweat glands, so they rely on breathing to regulate body temperature. High temperatures can significantly stress them. When the temperature exceeds 25°C, install a curtain at the air inlet to cool incoming hot air before it enters the house. This method can lower the internal temperature by 4–5°C and maintain cooling for 6–8 hours. If the temperature rises above 30°C, use a spray nozzle to mist the roof or the chickens directly every 2–3 hours. This can reduce the temperature by 6–8°C, helping to keep the birds more comfortable.
2. **Lower energy intake**: As temperatures rise, feed consumption decreases. For every 1°C increase above 25°C, feed intake drops by about 1.6%. To compensate, adjust the feed by reducing its energy content and increasing protein by 10%–15%. Use plant-based proteins instead of animal-based ones to reduce greasiness. Also, enhance the diet with twice as many multidimensional factors. Switching to granular feed improves palatability, encouraging better feed intake and overall nutrient absorption. It's best to feed during cooler nighttime hours, from 10 PM to 6 AM. Increase lighting to stimulate activity and feed 4–5 times during the night. Using vibrating drums can also encourage feeding and maintain strong appetites.
3. **Reduce stocking density**: Overcrowding increases heat stress. In summer, maintain appropriate stocking densities: 30–25 birds per square meter at 7–14 days old, 25–15 birds at 21–28 days, and 10–5 birds at 35 days. Group sizes should be around 300 birds, separated by fences to improve air circulation and reduce heat buildup.
**Second, ensure the "three guarantees":**
1. **Water supply**: Broilers need more water in hot weather due to increased respiration and evaporation. Provide enough waterers to ensure each bird has access. Keep the water clean and fresh to avoid contamination.
2. **Green feed**: Offer juicy green feed to boost appetite, aid digestion, and provide a cooling effect. These feeds are rich in nutrients and help the birds stay hydrated and comfortable.
3. **Ventilation**: Good airflow is essential to remove excess carbon dioxide and harmful gases. Keep windows and doors open for natural ventilation, and consider using exhaust fans to maintain a steady flow of fresh air.
**Third, focus on the "three defenses":**
1. **Disease prevention**: High temperatures weaken the immune system, making chickens more prone to diseases like coccidiosis and staph infections. Regularly disinfect the poultry house using broad-spectrum, non-toxic products such as 100 toxin-killing agents or sodium hypochlorite. Spray at 15 ml per square meter, keeping a distance of 50–80 cm from the flock. Disinfect 1–2 times weekly normally, and daily during heatwaves, reducing the concentration by 30%–50%.
2. **Moisture control**: Maintain humidity between 50% and 70%. Excess moisture can lead to poor feathering, dirt, and joint issues. Fill potholes, ensure proper drainage, and keep the coop dry to prevent mold and bacterial growth.
3. **Pest control**: Summer brings more mosquitoes and flies. Clean the surrounding area, fill sewage pits, install screens, and regularly spray insecticides to create a safe and hygienic environment for the chickens.
By following these practices, you can help your broilers stay healthy, comfortable, and productive even in the hottest months.
