Raise 10,000 chicken laying hens construction plan

Site selection and layout of broiler cage
The standardized construction mode of 1-2 million single-scale chicken farms has become the main body of laying hens in China. The site selection and layout of the farm should be in accordance with the "Measures for the Examination of Animal Epidemic Conditions". At the same time, the transportation is convenient. The special road with hardened pavement is directly connected to the site; the terrain is high, the wind is sheltered from the sun, the drainage is convenient; the water source is stable, and the water quality meets the national drinking water standard. . The layout should be considered from the perspective of facilitating epidemic prevention and organizational production. The site can be divided into production area, office area, living area, auxiliary production area, sewage and manure treatment area, etc., and the layout is based on the principle of dominant wind direction, terrain height and water flow direction. If the terrain is inconsistent with the wind direction, the dominant wind direction is dominant; the chicken house is oriented about 15 degrees east-west or south east (or west), which is conducive to improving the winter temperature and avoiding summer solar radiation, which is conducive to improving the ventilation of the chicken house; The spacing is 10-20 meters for brooding and 10-15 meters for laying hens.
Technical points of chicken cages
The field is divided into production area, living area and office area according to functions, and each area is completely separated. The production is divided into the brooding and laying area, the net and the sewage are separated, the biological safety control is better, and the layout is reasonable, which is conducive to health and epidemic prevention and disease control.
The type of the house is a closed house. The building is sturdy and durable, with good thermal insulation performance. The house environment is well controlled. When the temperature outside the house is -15 °C, the house environment can still meet the production requirements of the laying hen.
The two-stage breeding process is adopted, and the single-row all-in and all-out mode is adopted. The single-bred brooding and breeding house is 22,500, and the laying house is 15,000 laying hens. It adopts 3-layer step cage; nipple drinking water, stepped straddle with automatic feeding, wet curtain cooling, longitudinal ventilation, scraping slab mechanical cleaning. The disinfection facilities in the site are complete, equipped with high-pressure cleaning and disinfecting machines, ultraviolet disinfection lamps, and special spray-type spray disinfectors for chicken houses. After the sewage treatment is treated by the septic tank, it is used for fertilization on the farmland, and the chicken farm self-built the composting field. The diseased dead chicken is treated by fully enclosed cadaver fermentation. This model can meet the production requirements of large-scale laying hens. In this mode, the chicken farm environment is clean and tidy, the air quality of the chicken house is good, and the labor efficiency is high.
Savings
The farm construction mode adopts two-stage breeding methods of brooding and laying hens, which solves the problem of multi-batch feeding and multi-day-old chickens in the original three-stage breeding, which is conducive to epidemic prevention and avoids mixing in the same area. The incidence of infectious diseases caused by cross-infection is 80% lower than that of polyculture mode, and the cost of vaccines and veterinary drugs is reduced by more than 20%. The breeding mode of breeding and breeding is beneficial to the insulation of chick houses and avoids the transfer from brooding houses. The temperature difference stress of the breeding house, while reducing the artificial stress brought by the transfer group, improve the quality of the flock, and improve the utilization efficiency of the cage and reduce the cost of breeding.
The chicken house is constructed reasonably, using mechanical ventilation and wet curtain cooling system. The internal environment control can meet the demand of laying hens. The average temperature in the chicken house can reach above 13 °C in winter, and the temperature in the summer house can be maintained at 25.2 °C.
Under the farm construction mode, the per capita breeding amount can raise more than 5,300 chickens in the past; the 154-day laying hen feeding cost (excluding the cost of chicks) has been reduced from the previous 32.7 yuan to the current 29.5 yuan.
