Summer chicken three points
First, do a good job of "three down" - cooling, lower energy, lower density
1. Cooling
That is, lower the temperature of the house. Chickens do not have sweat glands. The heat generated in the body can only be lost by breathing, and its ability to adapt to high temperatures is poor. When the temperature exceeds 25°C, a curtain can be installed at the air inlet to allow the hot air to cool before entering the house. This method can reduce the temperature from 4 to 5°C, and maintain the cooling time from 6 to 8 hours. When the temperature exceeds 30°C, the nozzle can be sprayed with high and low mist to directly spray cold water to the roof or the chicken body. Spray once in 3 hours, the temperature in the house can be reduced by 6-8°C.
2. Reduce energy
That is, reducing the feed energy value. Experiments have shown that at 25°C or higher, the feed intake of broiler chickens decreases by 1.6% for every 1°C increase in the chicken house. It is appropriate to reduce the energy and increase the protein level by 10 to 15%. Plant protein can be used instead of animal protein feed, which can reduce The chicken eats greasy food and increases the multidimensional factor in the diet by 2 times. At the same time, granular feeds can be used to increase palatability, increase feed intake, and increase total nutrient intake of broilers. In the hot season, it is best to use night feeding. From 10 pm every night to 6 am the next morning is the coolest time, which is good for broilers. The method is: appropriately light bulbs, increase the excitability of broilers, feeding 4 to 5 times at night, and through the vibration drums, to drive the flock to maintain a strong appetite. In addition, summer broilers can use dry, uncontaminated river sand as litter, which not only facilitates broiler sand bath and chicken body heat dissipation, but also enables broilers to eat satay, which is beneficial to food digestion.
3. Drop density
That is, reducing the stocking density. Suitable density for broiler chickens in summer: From 1 to 2 weeks old, 30 to 25 eggs per square meter, 25 to 15 eggs from 3 to 4 weeks old, and 10 to 5 eggs from 5 weeks old to slaughter. It is advisable to use 300 animals per group. Flocks and groups are separated by fences to facilitate the circulation of air inside and outside.
Second, do a good job of "three guarantees" - water, security, security ventilation
1. Water retention
That is, to ensure adequate supply of drinking water. Summer temperatures are high, broiler's respiration is quickened, and the body's water evaporation is large, and its drinking water is obviously increased. Therefore, set enough sinks to ensure that each bird can drink enough water. In addition, keep drinking water clean and hygienic.
2. Bao Qing
That is guaranteed to feed a certain amount of green and juicy feed. Juicy green feed is rich in nutrition, good palatability, can promote the appetite of broilers, help digestion, both thirst-quenching and cooling, is conducive to rest in broilers.
3. Keep ventilation
That is, the house is well ventilated. Due to the high temperatures in the summer and the increased respiratory rate, concentrations of harmful gases such as carbon dioxide in the air have increased. Therefore, to ensure that the broilers have sufficient oxygen, they must be ventilated. They should always open doors and windows for ventilation, and they can install exhaust fans.
Third, attach importance to "three defenses" - prevent disease, prevent moisture, and prevent mosquitoes and flies
1. Disease prevention
That is to prevent disease. High temperatures will reduce the resistance of broilers and cause coccidiosis and staphylococcal diseases. Therefore, in addition to supplementing the feed with antibiotics, chicken house sterilisation must be carried out. Disinfectant should be selected as a broad-spectrum, high-efficiency, non-toxic disinfectant with no side effects and adhesion, such as 100 toxins, poisonous bacteria, and sodium hypochlorite, sprayed at 15 ml/m2, and sprayed at 50 to 80 cm from the flock. . In normal circumstances, 1 or 2 times per week, on a hot day, once a day, in the afternoon, while reducing the concentration of the drug by 30 to 50%.
2. Moisture proof
That is, keep the chicken house and the playground dry. The optimum relative humidity for broilers is 50-70%, and when the relative humidity is higher than 70%, the feathering, filth, and arthritic diseases will also increase. Especially in high temperature and high humidity environment, it is easy to breed microorganisms and induce the occurrence and spread of diseases. Therefore, the potholes in the playground should be filled to keep the drainage clear, and the weather is rainy and cloudy. In particular, the hen house should be kept dry to prevent mold growth.
3. Anti-mosquitoes
That is, preventing mosquitoes and flies from attacking the chicken body. In the summer, there are many mosquitoes and mosquitoes. In addition to paying attention to the health of the chicken house and sports ground, the weeds around the chicken house have to be cleansed, the sewage pits must be filled, the screens must be nailed, and the mosquitoes and flies must be sprayed regularly to ensure Broilers have a peaceful environment.
