With the rapid development of the chicken industry and fierce competition in the market, there can be no sloppy rearing and management, and if there is a problem at a certain point, it may cause huge economic losses. So what measures should be taken to improve the safe production of laying hens? 1 培育Cultivate healthy and high-quality spare laying hens: 1 Select cultivars with good breeds and diseases to purchase mutton chickens. In the early brooding period, the temperature inside the house should be maintained at 32 ~ 20 °C, the use of 40 watt bulbs to increase the brightness of the aerial lighting, to provide enough slots, fully fed; in the middle and late, should pay attention to ventilation, according to the growth and development of the flock, restrict feeding Feeding to prevent excessive fat accumulation from affecting later egg production. 2 Do a good job of disease prevention and immunization, especially infectious diseases such as chicken Newcastle disease, Marek’s disease, Ganpaul disease, and infectious bronchitis. Reduce mortality, improve uniformity, and cultivate qualified reserve flocks. 2? Strict anti-epidemic system: Establish a perfect system for epidemic prevention and implement it consistently. Establish an all-in and all-out system. Before entering chickens, clean and wash the chicken house and thoroughly disinfect it. After entering the chicken, remove the faeces and litter in time and properly handle it. Chickens are sterilized 2 to 3 times a week. A sterilizing tray is set up at the door of the hen house for stamping and tapping. Disinfectant is sprayed on a daily basis. Put on the epidemic prevention clothing when entering the house. Do not enter people in the house. Timely rodents kill flies to prevent birds from entering through the windows and prevent the spread of disease. Dead chickens are buried or burned in time. Clean the door of the chicken house and the surrounding environment on time and spray disinfectant at the same time. 3. Feed full-rate diets: Prepare diets based on local feed resources, egg production stages, and climatic conditions. After the formulation of the feed is determined, formulate it according to the raw materials and proportions in the formula, keep the full-price diet relatively stable, and do not frequently change the raw materials and their proportions in the formula, otherwise it will cause fluctuations in egg production. When the layer number of the chicken is transitioned, it should be progressive. Type transition. Regular feeding of diets, 2 or 3 times a day more appropriate, not to feed moldy material. 4? Amount of clean drinking water: Ensure that the chickens drink enough and clean water to avoid water cuts. Especially in hot weather, the lack of drinking water for a long time will inevitably lead to a drop in the production of eggs, and the death will increase when the heat stress increases. Drinking water in sinks or drinking fountains should be cleaned daily to remove waste and other contaminants, and then put in clean water; nipple drinkers should always check for dripping water, and when they find no water, they must repair it in time. 5? Control the light: 1 After the reserve hens are basketed, the lighting time should be increased slowly. Due to the differences in species, the speed of light increase is also different. Usually it is appropriate to increase by half an hour each week, and it is constant after about 27 weeks of age and 16 hours after daylight. Some broiler households have poor breeding conditions or poor management. When they start production, the body weight is small. At this time, lightening time can be increased by 15 minutes per week on the basis of strengthening feeding management, so that the opening weight is consistent with sexual maturity. 2 The lights are turned on and off at regular intervals. Due to the lack of light due to power outages, etc., candles should be used to supplement the light. 6? Appropriate ventilation: The air environment has a direct impact on chicken health and production performance. In addition to ventilation and dust removal, ventilation also improves air conditions and temperature control. In the summer, enhanced ventilation can reduce heat stress; in winter, emphasis on ventilation can reduce the harmful gases in the house, make the ammonia concentration lower than 2010-6, the concentration of hydrogen sulfide is lower than 1010-6, and the allowable concentration of carbon dioxide does not exceed 0 to 5%, it should be particularly pointed out that night ventilation must not be ignored. 7? The appropriate temperature and relative humidity: 1 the temperature is too high or too low, it will affect the chicken's activity, diet and physiological metabolism, thereby affecting the laying performance and feed efficiency. In cold weather, it should be kept cold and warm, and fed diets with high metabolic energy; in hot weather, it should be used to cool down and provide diets with appropriate nutritional levels. In actual production, try to control the temperature within the range of 10 ~ 27 °C. 2 Relative humidity does not affect the flock too much, but it can also cause serious harm when other factors work together. For example, high temperature, high humidity, or low temperature and high humidity may cause chicken disease. The former is prone to long-term survival of pathogenic microorganisms, and the heat dissipation of chickens is hindered. The latter tends to make the chicken body cold, the feed is expensive, and the relative humidity is too low, which can exacerbate airborne diseases. Opportunity, susceptible to infectious diseases such as respiratory tract. In general, it is better to prevent moisture and keep the house dry. 8? Remove diseased chickens, laid-off chickens, and low-yielding chickens: Observe the chickens regularly and eliminate the chickens without feeding value. Grab two stages. 1 After the start of production, it is a stage before the egg production rises by 80%. Observe the mental status of the chicken, the color of the chicken cocks, and touch the abdomen and the pubic symphysis joint to pick out the sick chickens and dummy hens. 2 After the peak period of egg production and after the egg production rate is reduced to 80%, the elimination of laid-off chickens, low-yielding chickens, and diseased chickens will be strengthened to improve feed utilization. 9? Reduce the stress factors: In the daily feeding and management, reduce the shock caused by a variety of internal and external noise; avoid various stressors such as hunger, cold and high temperature. In short, in the chicken-raising process, every detail of feeding and management is done well to ensure safe production, reduce costs, and increase economic efficiency.
