Green shell layer chicken and black chicken how to scientifically brood

Healthy chickens are the first and most crucial step towards the success of breeding. How to scientifically and efficiently brood has caused a great deal of concern and attention of the majority of breeding practitioners. Based on many years of experience, the author summarizes the following points: First, disinfection before entering the chicken. Completely remove organic matter before disinfection. Too much organic matter will affect the disinfection effect. Do not rush to clean after spraying the disinfectant. Wait for a period of time to allow it to come into contact with the bacteria and viruses and then perform the action. The fumigation must be long enough. Ensure that the gas is fully volatilized so as not to damage the respiratory mucosa of the chicks. If the chickens in the batch have a severe infectious disease, they must be fumigated, and the emptying time should be extended appropriately. Second, select the chicks off. Try to choose quality chickens from big manufacturers. Good chickens can be cured, but bad chickens are difficult to maintain. High quality and healthy chickens are derived from the purification, nutrition, management and incubation techniques of the flock. For longer hatching time (especially more than 48 hours), it is better not to pick up the dehydrated chicks. This kind of chicken is very difficult to raise. Third, the chick temperature is off. The temperature of brooding starts from 34 to 32 degrees, and the temperature of the young chicks should be low, and the temperature of the young chicks should be high. Afterwards, it will steadily decrease by 2 to 3 degrees every week until it is stable at around 21 degrees. Keep temperature constant and avoid large fluctuations in temperature. The thermometer is evenly distributed in the house and the height is adjusted at any time so that the bottom of the thermometer is the same height as the back of the chicken. Learn to look at the status of chickens Shi Wen: Evenly distributed, comfortable, suitable for the temperature; away from heat, open mouth wheezing, as the temperature is too high; close to the heat source, crowded do not love moving, as the temperature is low. Fourth, the chicks have humidity. One-week-old chicks need high air humidity and a relative humidity of 65% to 75%. Air drying causes dehydration of chicks, dry skin, dry chicken paws, and susceptibility to respiratory diseases. In the 1-2 weeks of the brooding house, put kettles on the stove to evaporate and humidify the air. Vinegar can also be used. High-temperature and high-humidity environments make chickens difficult to dissipate heat, and the heat and humidity are uncomfortable. In low-temperature and high-humidity environments, chickens dissipate heat more quickly, receive cold and cold, and their resistance decreases. Coops are too wet and prone to coccidiosis, chicken fleas and colibacillosis. Fifth, chick density is off. The number of young chicks should be determined according to the area of ​​the chicken house. If the density is too large, the growth rate will be slow, the slaughter time will be prolonged, the size will be different, the feed/meat ratio will increase, and the income will decrease. Density is too small to reduce the utilization of the house. The chicken-age chicken house has ample area and it is appropriate to enlarge the area for breeding. Although more heating costs will be charged, it will grow rapidly, grow evenly, and make more profits. When chicks are dense, they need to be expanded in time, especially in winter. Sixth, the chicks were ventilated. Ventilation is not an important part of this stage. In the early stage, insulation is the main factor, and proper ventilation is needed to prevent the oxygen in the fire from causing oxygen deficiency in the brooding room (to maintain ventilation during the winter season). The ventilator is left on the ceiling of the coop, ventilation from above, should avoid blowing cold air directly to the chicken. Mid-late broilers should pay full attention to ventilation and increase ventilation. Poor ventilation leads to a lack of oxygen in the houses and reduces the performance of broilers. Ascites disease increases in broilers. A large ammonia smell in the chicken house, damages the respiratory mucosa and conjunctiva, reduces the resistance of chickens, and increases the risk of infections of respiratory diseases, E. coli diseases, and other viral diseases. Seventh, the chicks light off. One week of chicks, 24-hour light, using 40-60 watt bulbs, chicks as soon as familiar with the new environment, increase intake, lay the foundation for weight and immunity. Eighth, drinking water to open food off. Recent studies have found that drinking water as early as possible is beneficial to the development of intestinal development and immunity of chicks. During the brooding period, the number of drinking fountains should be more to facilitate the chicks to drink water, especially for young chicks and young chicks. The number of drinking fountains should be appropriately increased. Ninth, opening the drug off. It is mainly the purification of chickens and the full supply of nutrients. The selection conditions of the open purification drug: (1) Broad spectrum: Effective against Escherichia coli, Salmonella pullorum, and slow call mycoplasma; (2) High efficiency: rapid bactericidal and antibacterial; (3) Long-acting: long duration of action; (4) No hazards: low toxicity; (5) Unilateral: Western medicine ingredients unilaterally to prevent the situation in the late period without medicine; (6) The big market has been tested and taken to others' success. The choice of opening nutritional medicine: high content, complete nutrition, easy absorption, easy to use. The good beginning is half of the success. The healthy chicks laid a solid foundation for the middle and late breeding, and the successful breeding began from the scientific brooding.
