First, the production performance of female chicken Hen egg production per egg 180 to 230, egg fertilization rate of 85% to 90%, fertility hatching rate of about 90%, 90 days of age up to 1.25 kg, consumption of about 3.5 kg, The breeder can lay eggs around 165 days of age and have an incubation period of 21 days. Second, hatching 1. Keeping the temperature at an ambient temperature of 24 to 26°C, egg surface temperature of 1 to 19 days at 37.8°C, and hatching at 37 to 37.5°C. 2. After 1 to 7 days of humidity control, the relative humidity was maintained at 60% to 65%, 8 to 18 days at 50%, and 19 to 21 days at 70%. 3. The air in the incubator must be kept fresh, the wind speed is normal, and the size and location of the vents are appropriate. 4. Turning the egg generally turns the egg once every 2 to 3 hours. The turning angle of the turning egg is 45 degrees before and after the horizontal position. Stop turning the eggs after 18 days of incubation. 5. After drying the eggs, take them 1 to 2 times a day before closing and close them. Before closing, close the door and dry the eggs 2 or 3 times a day. Close the door and go to a large batch of chicks to dry the eggs 3 to 4 times a day. 6. According to the egg, the whole brooding process is performed 2 times. The first time the egg is hatched 5 to 6 days after hatching, and the second time is 19 to 20 days after hatching. Third, the chicken breeding management 1. Sterilization The brood chamber shall be sterilized before entering the chicks. For each cubic meter, 42 ml of formalin and 21 g of potassium permanganate shall be used for fumigation. All utensils shall be thoroughly disinfected with 0.1% benzalkonium disinfectant. 2. Temperature control Under normal circumstances, keep the temperature of the brooding chamber as follows: chicks 1 to 2 days old 34 to 35°C, 3 to 7 days old 32 to 33°C, then descend 2°C per week, then drop to 20 to 21°C. 3. Feeding can feed general full-priced pellet feed, and conditional can add 4% dry powder or 4% imported fish powder. 1 to 7-day-old chicks should be fed a small number of meals, fed 8 to 10 times a day, after all the day feeding, so that chicks are free to feed. 4. Drinking water 1 to 7 days of age should be fed cold water, add 2% to 5% of glucose and vitamins and antibiotics, after which the chicks can freely drink clean tap water. 5. The brood density is 1 to 2 weeks old and stocked 30 to 40 per square meter, 3 to 4 weeks old 20 to 30 per square, 5 to 6 weeks old 15 to 20 per square meter, 7 to 8 weeks old per square Rice stocking 10-15. IV. Feeding and management of young chickens 1. Feeding young chickens can be fed with full-grain pellets, and feeds can also be prepared on their own, feeding them 2 or 3 times a day. 2. Disease prevention and control to maintain the cleanliness of the chicken house, cleaning the house once a day, weekly with 0.1% concentration of benzalkonium bromide or 3% to 5% concentration of the spray solution of the spray disinfection of 1 time. Do a good job in the prevention and treatment of diseases such as white spot disease, coccidiosis, and colibacillosis. Five, immunization chicks hatched on the same day Marek's vaccine; 7 to 9 days with Newcastle disease II seedlings eye drops or nasal drops (1-2 drops each); 12 to 14 days with infectious bursal disease vaccine seedlings drinking water Immunization was repeated 20 to 22 days; 25 to 26 days of age were immunized with 2 doses of Newcastle disease II seedlings; intramuscular injections of Newcastle disease I strains were available after 2 months of age. The immunization period is about 1 year. China Agricultural Network Editor
