The brooding period is 0 to 21 days. Because the chicken's body temperature regulation, digestion and other capabilities are still not perfect, it has poor resistance to the external environment and disease, and it is easy to die. Therefore, it must be meticulously reared and carefully managed.
1. Brooding brooding larvae should be kept with chicks of the same size and breed. Male and female chicks should be kept in separate pens. The brooding house is required to have good sealing performance so as to facilitate the insulation of the chicken house. The brooding house can be paved with concrete floor, which can drain water and facilitate cleaning, washing and disinfection of the house. There should be a disinfection pool at the door of the shed, and the shoes can be entered before entering the house.
2. Breeding equipment Brooding methods can be divided into ground free-range, floor nets and cages. When the ground is free-range, winter and spring should be paved with 5-7 cm thick mat grass, summer ground sand and soil plus a thin layer of mat grass. The mat grass should be clean, dry, free from mildew and twisted into about 10 centimeters long. After being brooded, the bedding should be cleared out of the house and composted with the feces and cannot be reused. When using floor nets, the nets can be made of wire or wood or bamboo. The spacing (or mesh size) of the net should be appropriate, generally 1.2 cm pitch or 1.2 cm square mesh, the height of the mesh surface is 60-70 cm, and the entire net surface is active so that after the chickens are transferred out, the net is opened. Remove the noodles and clean the chicken house. In the case of ground rearing or floor net raising, the number of chickens should be provided and the sink and trough should be evenly placed. High temperature insulation umbrella heating. In areas where premises are small and where electricity is more convenient, stacked-type electric brooding cages can be used for brooding. Each cage has 4 layers and a total of 1,200 to 1,600 broods can be bred.
3. Brood density The rearing area should increase as chicks grow. Feeding 50 to 60 per square meter at 1 week of age, raising 30 to 40 eggs per square meter at 2 weeks of age, and raising only 20 to 30 eggs per square meter at 3 weeks of age.
4. Brooding temperature Within 3 weeks of brooding, whether the temperature in the broiler is appropriate or not is the key to the success or failure of the brooding work, neither too high nor too low. Freshly hatched chicks are required to live under a warm umbrella at 35-38°C, and then drop about 3°C ​​per week. The temperature of the chicken house is suitable for observing the performance of the chickens: it is too cold and the chickens get together; too hot, the chickens open their mouths for gasping; at a suitable temperature, they are lively and comfortable. During the brooding process, attention should be paid to adjusting the flock. We must make small groups of frail, stunted, and unstable individuals, give special care, be nearer to heat sources, have lower density, have sufficient feed water, and add vitamins to promote the restoration of health.
5. Brood Humidity The temperature of the brooding room is high, which often leads to low humidity and dry air. The chicks lose their water and affect the health. When they are severe, they cause dehydration. When the humidity in the brooding house is low, water can be sprinkled on the ground. The brooding chamber maintains a relative humidity of 60% to 65% and can be measured by hanging a wet bulb thermometer indoors. In the late brooding period, the humidity is not strict and the normal humidity can be maintained.
6. Brooding Ventilation only requires natural ventilation devices. Generally, the hoods, windows, and roof caps are sufficient to meet the requirements of the chicks for ventilation.
7. Brooding Light The chick requires a certain amount of light time and light intensity. In a closed chicken house, 1 to 2 days old chicks need to light for 23 hours, 3 to 7 days old to take 20 hours, 2 weeks old to take 16 hours, 3 weeks old chicks to take 12 hours, and mother to chicks to 14 hours. Light intensity: 0 to 10 days of age, 3 watts per square meter, 11 to 21 days of age, 2 watts per square meter, should pay attention to the uniform lighting.
8. Brooding hatching Chicks have a small body weight, consume less material, and increase weight quickly. Therefore, it is required that the feed quality is good, the nutrition level is high, and the health standards are met. Reference feed formulations such as: corn 50%, wheat flour 3%, wheat bran 2%, bean cake 31%, fish meal 12%, bone meal 1.1%, salt 0.4%, trace elements, vitamins, amino acids, somatotropin, antibiotics Drugs and other additives 0.5%.
9. Feeding and watering chicks start eating 24 hours after hatching. They can be allowed to drink 5% glucose water first, and then 2 to 3 hours before feeding dry broken minced rice or corn flour. After 1 to 2 days, they can be fed. Feed batch materials. One week old was fed 6-8 times per day and night, 2 weeks old 5-6 times, 3 weeks old 4-5 times. After drinking, the drinking water with good free drinking water and water temperature of 20-25°C can be used. The number of long troughs and gutters used in the brooding period depends on the number of feedings. In principle, each chicken has a length of 2.5 cm and a trough of 0.6 cm.
10. Observe chickens during brooding and enter henhouses frequently. Observe the spirits, diet, and excrement of the chickens. If abnormalities are found, identify the causes promptly, confirm the condition, and isolate, treat or eliminate them in time. Targeted medication prevention.
11. The chicks have broken wings to prevent warts and reduce flying ability. They can cut off and cut off the last joint of the left or right wings within 10 days of age.
