In order to ensure the health and productivity of broiler chickens during the hot summer months, it's essential to implement a comprehensive management strategy. This involves focusing on three key areas: "three down" (cooling, energy reduction, and density control), followed by "three guarantees" (water, feed, and ventilation), and finally, "three defenses" (disease prevention, moisture control, and pest management).
First, focus on the "three down" approach:
1. **Cooling**
Broiler chickens are highly sensitive to heat because they lack sweat glands and rely on respiration for cooling. When temperatures exceed 25°C, installing a curtain at the air inlet can help cool incoming air, reducing indoor temperatures by 4–5°C and maintaining this effect for 6–8 hours. If temperatures rise above 30°C, misting systems can be used to spray water directly onto the roof or the birds, lowering the temperature by 6–8°C every 3 hours.
2. **Reduce Energy Intake**
High temperatures can significantly reduce feed consumption. For every 1°C increase in temperature above 25°C, feed intake drops by about 1.6%. To counter this, it's advisable to lower the energy content of the feed while increasing protein levels by 10–15%. Using plant-based proteins instead of animal-based ones can also help reduce greasy feed and improve overall digestion. Feeding at night, when it's cooler, can encourage better feed intake. Additionally, using sand as litter not only helps with heat dissipation but also allows for natural dust baths, aiding in digestion and comfort.
3. **Lower Stocking Density**
Reducing the number of birds per square meter is crucial during hot weather. For example, from 1–2 weeks old, aim for 30–25 birds per square meter, decreasing to 10–5 birds per square meter when they're older. Keeping groups of around 300 birds and separating them with fences improves air circulation and reduces stress.
Second, ensure the "three guarantees":
1. **Adequate Water Supply**
During summer, broilers drink more due to increased respiration and evaporation. Provide enough drinkers so that each bird has easy access to clean, fresh water at all times. Regularly check and maintain the cleanliness of the water sources.
2. **Provide Green and Juicy Feed**
Including green, juicy feed in the diet helps keep the birds hydrated and supports their appetite. These feeds are rich in nutrients, promote digestion, and have a cooling effect, helping the birds stay comfortable.
3. **Ensure Proper Ventilation**
Good airflow is essential to remove excess heat and harmful gases like carbon dioxide. Keep doors and windows open whenever possible, and consider installing exhaust fans to enhance air circulation. This ensures that the birds receive sufficient oxygen and remain healthy.
Third, focus on the "three defenses":
1. **Disease Prevention**
High temperatures weaken the immune system of broilers, making them more susceptible to diseases like coccidiosis and staph infections. Along with adding antibiotics to the feed, regular disinfection of the chicken house is necessary. Use broad-spectrum, non-toxic disinfectants such as sodium hypochlorite or other safe alternatives, applying them at recommended concentrations and frequencies.
2. **Moisture Control**
Maintaining a relative humidity of 50–70% is ideal for broilers. Excess moisture can lead to poor feathering, dirt, and joint issues. Ensure the chicken house and surrounding area are dry by filling potholes, keeping drainage clear, and avoiding damp conditions that promote microbial growth.
3. **Pest Control**
Summer brings an increase in mosquitoes and flies, which can irritate and harm the birds. Maintain a clean environment by removing weeds, covering sewage pits, and installing screens. Regular spraying of the area with safe insecticides helps keep pests at bay, ensuring a healthier and more comfortable living space for the broilers.
By implementing these strategies, you can effectively manage the challenges of summer and support the well-being and performance of your broiler flock.
Gas Grill
The gas oven is a modern cooking device that combines efficient heating and easy operation. It uses clean gas as an energy source to heat ingredients quickly and evenly through a precisely controlled flame, and whether it is baking pizza, barbecue or baked bread, it can be easily harnessed to bring mouthwatering taste. Gas ovens are not only easy to operate and quickly preheat, but also energy efficient, making them ideal for modern kitchens and commercial dining venues.
When the Gas Pizza Oven is working, the gas flow is controlled by the gas valve. After the ignition device ignites the gas, the flame burns in the furnace to produce high temperature. Heat is transferred to the pizza through the furnace wall, which heats it evenly and gradually RIPS it. Gas pizza ovens are usually equipped with temperature control systems that can precisely adjust the baking temperature to ensure the baking effect of the pizza.
High efficiency: Gas Pizza Oven heating speed, can reach the required baking temperature in a short time, improve baking efficiency.
Temperature control: Equipped with advanced temperature control system, the baking temperature can be accurately adjusted to meet the baking needs of different pizzas.
Environmental protection and energy saving: Gas as a clean energy, combustion produces less waste gas, less pollution to the environment. At the same time, the gas pizza oven has a high energy efficiency ratio, which can effectively reduce energy consumption.
Easy to clean: Components such as furnaces and baking nets are usually made of easy-to-clean materials, which facilitate daily maintenance and maintenance.
