At present, most of the chickens are housed in open chicken houses. In the growing season, all-in and all-out systems are adopted, and most of them are raised on the net or raised on the ground. 1. Temperature: 34 to 36°C in 1 to 2 day old brooders, 28°C in room temperature, 33 to 35°C in 3 day old brooders, 28°C in room temperature, 1 week old, 2 drops in brooders per week °C, room temperature drop 1 °C; 4 to 5 weeks old can be warm. During the warm-up period, the temperature is most likely to avoid cold and hot, so as not to cause a large number of chicks to die. 2. Density: The breeding density in the incubating period is 30 to 40 per square meter, and the temperature for de-warming to 12 weeks is 15 to 20 per square meter, and after 12 weeks of age, it is 7 to 10 per square meter after the opening. 3, open food and drinking water: You can directly use chicken material to eat, but must be carried out after drinking water. Drink water to ensure the quality of health, in the heat preservation period to feed the sterilized or filtered water. Since the broiler chicks are very susceptible to gastro-intestinal disease and affect the survival rate of brooding, gentamycin should be added to drinking water within 1 week of age, 1000 international units per day per bird. Only, 2 weeks old 2000 international units/day. , 3rd week 3000 interstitial units/day. Only. 4, light: 0 ~ 7 days of age, 22 hours a day light, 8 days of age to the first 5 weeks of age for 16 hours of light, 6-18 weeks of natural light, after a week increase of 0.5 hours of light, increased to 28 weeks It lasts for 17 hours and it is maintained for 17 hours until 64 weeks of age. The light intensity is: 20 lux before opening and 40 lux later. Light must be evenly distributed. 5. Grouping: Strong and weak grouping at each growth stage. After warming, male and female were reared in groups. 6, keep a quiet feeding and management environment: the chicken is a lively nerve type, any abnormal noise and foreign matter will cause the entire group to produce stress and run, scream and flutter, such as in the production of eggs, will cause production Egg rate and hatching rate decreased. Therefore, all operations of the husbandry and management personnel must be regular so that the hens can produce good and familiar conditional reflexes, and actions should be light and not rude. The hen is light and has a certain ability to fly. Therefore, the fence of the playground outside the house should be 2 to 3 meters high. 7. Chickens are susceptible to Marek's disease. Therefore, Marek's vaccine must be injected within 24 hours after hatching. Others, such as Newcastle disease and infectious branch inflammation, should be subjected to chicken immunization procedures. 8, the broiler chicken breeding period does not require restrictions on feeding, there is no need to cut off, because it is not easy to accumulate fat, but also rarely fight or the formation of cockroaches, but must provide nutritious feed. 9. The demand for constant and trace minerals and vitamins for ladybirds is higher than that for chickens. In the daily feeding process, it is about 8%~13% higher than that of ordinary chickens. 10. The level of nutrients such as crude protein and energy is not high for ladybirds. As long as they are fresh, the full price of chickens can be kept well. However, because the chicks are small, they are 1 week old for chickens. The flowers are more suitable. The chicken granules are fed from 2 to 3 weeks old. The size of the feed pellets should be adjusted to avoid starvation and waste.
