“There are many varieties of current layer chickens, such as Hyland, Roman, Isha, Decca, etc. These varieties can achieve good production benefits under the corresponding feeding and management conditions.†Zhang Jianqin, Assistant Professor of the Academy of Action, Northwest Agriculture and Forestry University In an interview with reporters on August 20, he said: “Since the climate, environment, and feeding conditions vary widely across China, different varieties perform differently in different regions. Therefore, when choosing a variety, the first thing to do is to select a large amount of local livestock and perform well. The chicken species should be followed by chicks that have certain breeding scale, feeding and management conditions, and better disease purification. Cultivate quality and robust chicks During the brooding period, temperature and light must be controlled according to the corresponding breeding manual. In general, the brooding temperature starts from 33°C and decreases by 2°C per week up to 21°C; the light starts from 24 hours a day and decreases from 2 hours to 12 hours per week. Routine immunization procedures for vaccination, 8 to 10 days of age cut off, pay attention to ventilation, with vertical ventilation, wet curtain ventilation as well. The key to the growth period is to grasp weight control and increase uniformity. Practice has proved that the body weight uniformity of 16-18 weeks is positively correlated with the persistence and survival rate of laying eggs. Light has a direct effect on improving the survival rate of laying hens and promoting egg production. Chicks were given 24 hours of light at 1 to 2 days of age to facilitate feeding and later gradually changed to constant light or natural light. During the breeding period, natural light is the main source, and conditions can be kept under constant light for 8 to 12 hours. Reduce feed costs Feed costs for egg farms account for 60% to 75% of the total cost, and some even reach 80% to 90%. If the feed cost is reduced by 0.1 yuan/kg, a single layer of 500-day-old co-consumption feed is calculated at 50kg, and feeding 10,000 layer chickens can save 50,000 yuan in feed costs. 1 Open up feed resources. Apply raw materials that are inexpensive, nutritious, self-produced, or easily sourced, according to the physiological characteristics of chickens at different stages, so that a reasonable diet can be prepared. 2 self-provided full-priced feed. Purchase premixes from manufacturers with reliable quality and reputation, and formulate full-price feeds according to the reference recipe. This can reduce transportation costs and intermediate links, and the quality is reliable. The cost can be reduced by approximately 10% to 20%. 3 reasonable processing. Crude particle size is too coarse, chickens are prone to picky eaters and cause wastage; crushing is too fine, palatability is poor, and the processing fee is high, each chicken will increase the processing fee by 0.6 to 1.0 yuan per year. Strengthening the prevention and control of disease in egg farms Egg farms are generally immune to Marek, Newcastle disease, infectious bursa, infectious bronchitis, fowl pox and egg drop syndrome. When performing immunization procedures, care should be taken to select vaccines, preserve them, and administer them. Faeces and dead chickens are bad factors in the spread of disease. Dead chickens should be buried or decontaminated. Never put chicken droppings near the house. Do a good job of daily hygiene and regular disinfection work, especially after chicken excrement must be thoroughly cleaned and carefully disinfected.
