One should pay attention to insulation. Due to the small body size, short hairiness, and poor thermoregulation, poor resistance to cold, proneness to colds and diarrhea, young chicks may affect their growth and death. Therefore, we must do a good job of insulation. In the first few days, the temperature in the brooding room was higher, generally maintained at 32-33Â°C. With its growth and development, the temperature can be gradually reduced, usually 2-3 Â°C per week, to maintain about 23 Â°C after 4 weeks of age. Second, keep dry. The prostitutes like to dry and fear moisture. Normal 1-7-day-old chicks require a relative humidity of 60-70%, and relative humidity can be maintained at 50-60% after one week. The humidity in the room is too high, and dry pads can be changed frequently. If the humidity is too low, kettles can be placed on the stove to boil water to generate steam humidification. Third, light should be reasonable. Reasonable lighting can strengthen the blood circulation of the prostitutes and improve the body's immune function. Normal chicks can take 24 hours of light at 1-2 days of age, but the lights should not be too bright as long as the chicken can see the food can be eaten; 3-4 days of age in addition to the night feeding lights, generally do not turn on the lights during the day, in order to facilitate the prostitutes to rest After 15 days of age, if the weather is warm, it can increase the sun's rays to kill bacteria and prevent disease. Fourth, the density should be suitable. The density of the chickens is too large, the indoor air in the brooding room is turbid, the diseases are easy to be infected, the chicks eat too much, and the growth and development are affected; the chicken density is too small, the utilization rate of the houses and equipment is reduced, the brooding cost is increased, and the feeding efficiency is affected. The appropriate breeding density for the young chicks: Generally 1-2 weeks old, about 30 eggs per square meter can be reared, and then the number can be reduced by 5 eggs per week as the age increases. By the age of 7-8 weeks, 8-10 animals can be kept per square meter. Fifth, scientific feeding. The chicks can eat and feed 24 hours after hatching, but they should be fed with drinking water before eating. Usually two thousand-thousandths of potassium permanganate solution is used to allow the chicks to freely drink water to clean the stomach and stomach. A few days later, 5% brown sugar or glucose can be added to the water to facilitate the absorption of the egg yolk by the chicks. When feeding is started, millet or corn crushed flour may be steamed (appropriately half-baked) with an appropriate amount of yolk and sprinkled on a plastic sheet or white paper after being crushed with cold to allow the chicks to learn to feed. The hatchlings within 15 days of hatching should be fed 5-6 times a day (4 times a day for 4 times in the evening) and gradually transition to 4 times after 15 days of age. Each feeding should not be too much. At the same time, we must constantly provide clean drinking water, and water may be added with appropriate amounts of vitamin antibiotics. Sixth, we must do a good job of prevention. The common diseases of the prostitutes are white psoriasis, coccidiosis and Newcastle disease. At 3 days of age, feed 2 days of Trimethoprim (2 tablets plus 1 kg of water) or add 0.3-0.5% sulfa drugs to the diet to prevent rickets. 7-10 days of age with normal saline (or cold water) 10-20 times dilution of chicken Newcastle disease II series vaccine to the chicks, nasal drops, each 1-2 drops of chicken Newcastle disease prevention. After 20 days of age, each 200 chickens were fed with 100,000 units of penicillin at a time and fed for 3 days to prevent coccidiosis and chickens from defeating. After 45 days of age, each chicken was injected with a 100-fold diluted chicken Newcastle I. The vaccine is 0.4 ml. In addition, the chicken house should be clean and sanitary, utensils should be cleaned every day, and disinfected regularly. Disinfection tanks should be set at the entrance and exit of the house. At the same time, we must also pay attention to rodent-proof, fire prevention, and theft prevention.
