4.2.1 According to the production process requirements of livestock and poultry farms, the locations of various buildings (structures) shall be arranged according to functional zoning to provide a good production environment for livestock and poultry production. Livestock and poultry farms should generally be divided into living management areas, auxiliary production areas, production areas and isolation areas. 4.2.2 Make full use of the original terrain and topography of the site. On the premise of ensuring that the building has a reasonable orientation and meets the requirements of lighting and ventilation, try to arrange the long axis of the building along the contour line of the site to minimize the amount of earthwork and foundation engineering costs. 4.2.3 The living management area of ​​the livestock and poultry farm is mainly arranged with office rooms for management personnel, business rooms for technical personnel, living rooms for employees, personnel and vehicle disinfection facilities, guards, gates and site walls. The living management area should generally be located in the upwind or crosswind direction of the dominant wind direction of the site throughout the year, and should be concentrated on the inside of the gate of the site. 4.2.4 The gate of the livestock and poultry farm should be located at the junction of the main road of the site and the road outside the site. The facility layout should ensure that outsiders or vehicles must undergo mandatory disinfection and be allowed to enter the site by the guard. 4.2.5 The distance between the fence and general buildings should not be less than 3.5m; the distance between the fence and the livestock and poultry house should not be less than 6m. 4.2.6 The auxiliary production area of ​​the livestock and poultry farm is mainly arranged with water supply, power supply, heating, equipment maintenance, material warehouse, feed storage and other facilities. These facilities should be arranged close to the load center of the production area. 4.2.7 The production area is mainly arranged with various livestock and poultry houses and corresponding milking halls, hatching halls, egg warehouses, shearing rooms, medicinal baths, artificial insemination rooms, embryo transplant rooms, loading platforms, etc. The production area and other areas should be strictly separated by walls or green belts, and a second personnel changing and disinfection room and vehicle disinfection facilities should be set up at the entrance of the production area. These facilities should have two exits, which are connected to the living management area and the production area respectively. 4.2.8 The orientation of the livestock and poultry houses in the production area should generally be southward with its long axis, or within 40° south-east or west. The distance between the two parallel side walls of each adjacent livestock and poultry house with parallel long axes is preferably controlled at 8m to 15m when there is no outdoor playground; when there is an outdoor playground, the distance between the railings of adjacent playgrounds is preferably controlled at 5m to 8m. The distance between the end walls of each adjacent livestock and poultry house should not be less than 15m. 4.2.9 Facilities that serve as logistics channels inside and outside the production area of ​​the livestock and poultry farm should be arranged near the roads connecting the inside and outside of the production area. 4.2.10 Storage sites for bulk materials such as silage, hay, root and tuber feed or bedding should be arranged in the edge of the livestock and poultry house in accordance with the principle of storage and use, and should have good drainage, facilitate mechanized operations, and meet fire protection requirements. When calculating the required storage facility volume, the bulk density of silage is calculated as 600kg/m2~700kg/m2, and the bulk density of hay is calculated as 70kg/m2~75kg/m2. 4.2.11 The feed inlet of the concentrate feed warehouse is opened in the auxiliary production area, and the discharge port of the concentrate feed warehouse is opened in the production area to prevent the cross-use of material transport vehicles inside and outside the production area.
4.2.12 The quarantine area is mainly equipped with veterinary rooms, quarantine houses and farm waste treatment facilities. The area should be located downwind of the dominant wind direction of the farm throughout the year and at the lowest point of the farm. The distance from the production area should meet the requirements of veterinary health and epidemic prevention. There should also be appropriate sanitary and epidemic prevention distances between the feces and sewage treatment facilities and other facilities in the green belt and the quarantine area. The quarantine area is connected to the production area by a dedicated road and to the outside of the farm by a dedicated gate.
4.3 Farm roads
NY/T682—2003
4.3.1 Farm roads are required to ensure traffic under various climatic conditions and prevent dust. There should be clean roads for people to walk and transport feed, dirty roads for transporting feces and dead livestock and poultry, and dedicated channels for loading livestock and poultry products for transportation. 4.3.2 The cleaning road is also the main road of the site. It is advisable to use cement concrete pavement, or flat stones or strip stones. The width is generally 3.5m~6.0m, the horizontal slope of the road surface is 1.0%~1.5%, and the longitudinal slope is 0.3%~8.0%. 4.3.3 The surface of the dirt road can be the same as the cleaning road, or crushed stone or gravel pavement, lime slag pavement. The width is generally 2.0m~~3.5m, the horizontal slope of the road surface is 2.0%~4.0%, and the longitudinal slope is 0.3%~8.0%. 4.3.4 The roads in the site are generally arranged parallel or vertically with the long axis of the building. The cleaning road and the dirt road should not intersect. The minimum distance between the road and the outer wall of the building is 1.5m when there is no exit and 3.0m when there is an entrance. 4.4 Vertical design
4.4.1 The ground elevation inside the livestock and poultry house should be 0.2m~0.4m higher than the ground elevation outside the house, and coordinated with the elevation of the road in the field. The design elevation of the road in the field should be slightly higher than the elevation of the road outside the field. In addition to preventing the site from being flooded, the ground elevation of the field should also be coordinated with the elevation outside the field. 4.4.2 When the terrain of the field is complex or the slope is large, it should be arranged in steps, and the height of each step should meet the driving slope requirements. 4.4.3 The field implements the principle of rainwater and sewage separation, and organized drainage can be used for natural precipitation in the field. The sewage in the field should be discharged through underground pipes and centrally treated in accordance with the provisions of GB18596. 4.5 Field greening
4.5.1 Select flowers, plants and trees that are suitable for local growth and harmless to humans and animals for field greening, and the greening rate shall not be less than 30%. 4.5.2 The distance between trees and building exterior walls, fences, road edges and drainage ditch edges should be no less than 1m.
