layout of the broiler farm.

1) Zoning planning area

Chicken farms are usually divided into production areas, management areas or living areas, and isolation areas. Compared with other districts, the management area is more closely connected with the society, and it is easy to spread diseases. The production area should be separated when the site is built, and foreign personnel and vehicles are not allowed to enter the production area. In order to avoid the introduction of foreign pathogens. The living quarters for employees should be located in the upper wind and higher terrain. In order to prevent the chicken farm from polluting the living environment and infectious diseases.

The production area should be built in the core area of the chicken farm. The broiler chickens in the production area are different in age and type, and their physiological characteristics and physical functions are also different. Therefore, it is necessary to carry out sub-district planning. Separate chickens of different ages and types. The day-old chicken flocks are placed in the wind direction, and the high-lying isolation area is used to isolate and deal with sick chickens.

(2) Coop distance

Coop spacing is also an important environmental condition that affects the healthy life of broilers. If the distance between chicken houses is too small, it is easy to cause pathogens to spread between chicken houses when ventilation. In the event of a fire, it is easy for seedlings to reach the entire chicken house and flock. In addition, it is easy to cause disease in chickens. Therefore, a proper distance should be kept between each chicken house. The distance between open chicken houses is 20-30 meters, and the distance between closed chicken houses is 15-25 meters. A few days ago, the chicken coop spacing of chicken farms in my country is too small (3-8 meters), which has seriously affected the health and production performance of the chickens.

3) The orientation of the chicken house

The orientation of the chicken house is also an important environmental factor, which also plays an important role in the healthy growth of broilers and cannot be ignored. The choice of the orientation of the chicken house should first consider the wind direction, location, lighting, ventilation and sewage. The chicken house faces south, that is, the longitudinal axis of the chicken house is east-west, which is more suitable for open houses in most areas of my country. This orientation can ensure that the chicken house is warm in winter and cool in summer. The ventilation effect in the chicken house has a great relationship with the uniformity of airflow and the size of ventilation. It is generally required that the angle between the longitudinal axis of the chicken house and the dominant wind direction in summer is 45 degrees-90 degrees.

(4) Arrangement of chicken coop

The main building in the production area is the chicken house. The arrangement of the chicken house is determined according to the breeding scale, site shape and size. Generally, there are several forms such as single row, double row and multiple rows.

(5) Roads and storage fields

The chicken farm should set up clean and polluted channels, clean equipment, discharge dirt, and clean sewage. Ensure the cleanliness of the chicken farm environment. The manure storage yard is generally set in the middle of the chicken house, near the road. Convenient for manure cleaning and transportation. At the same time, an isolation belt needs to be set around. The gate of the chicken farm is provided with a disinfection pool and disinfection room for the disinfection of personnel, equipment and utensils.
