Layout Design of Chicken House in Broiler Farm
Whether the layout of chicken houses in broiler farms is appropriate or not directly affects the investment in infrastructure, management, production organization, labor productivity, economic benefits, environmental conditions and epidemic prevention and health of the farms. Therefore, reasonable layout of chicken houses is very important, and the following main principles should be followed.
1 chicken house layout
According to the local main wind direction and the location of the broiler farm, the wind direction is from the upper wind direction to the lower wind direction, and the terrain is from high to low. The production area should arrange the breeding chicken house and commercial chicken house in turn. The order of breeding henhouse is brooding henhouse, breeding henhouse and laying henhouse. The incubator should be a certain distance from all the chicken houses. It can be built near the entrance of the production area. Large-scale chicken farms should have
separate incubators outside the chicken farm, and enclosures or green isolation belts around the incubator or incubator should be set up.
2 chicken coop arrangement
1) Chicken houses in the farm should be arranged horizontally and lengthwise; buildings should be arranged as square as possible to avoid long and narrow rows, which will lead to greater transportation distance of feed and manure and inconvenience in management. The number of chicken houses is less than 4, and can be arranged in a single row; if there are more than 4 chicken houses, they can be arranged in two or more rows.
2) When using single-row chicken house layout, one side is the clean road, if the chicken house adopts longitudinal negative pressure ventilation, the air inlet should be placed on this side, and the other side is the dirty road, the exhaust fan should be placed on this side. When the double-row chicken house layout is adopted, the middle is a clean passage, and the air intake is also placed on this side; the two sides are dirty passages, and the exhaust fans can be placed.
3) The layout of more than two single-row chicken houses should follow: East-West direction, north-south direction; clean road east, dirty road west; horizontal south ventilation, vertical west ventilation.
4) The layout of two or more double-row chicken houses should follow: East-West direction, north-south direction; clean road in the middle, dirty road on both sides; horizontal south ventilation, vertical dirty road.
3 chicken house orientation
The choice of the orientation of the barn is related to the local geographic latitude, location environment, local climatic characteristics and construction land conditions. The appropriate orientation can make reasonable use of the solar radiant energy on the one hand, avoiding excessive heat entering the house in the summer, and allowing the solar radiation to enter the house to maximize the temperature in the winter; on the other hand, it can be rationally utilized. Leading the wind direction and improving ventilation conditions, thus providing the possibility of obtaining a good housing environment.
4 spacing of henhouse
The spacing between the houses is directly related to the lighting, ventilation, epidemic prevention, fire protection and floor space of the house. The spacing of the houses can be designed according to the following aspects.
1) Determine the distance between the houses according to the sunshine. Determining the spacing of the houses requires that the front row of houses does not block the rear sun.
2) Determine the distance between the houses according to ventilation. The proper distance between the houses ensures that the downwind has sufficient ventilation to the house and is protected from the dirty air discharged from the upwind. When the distance between the houses is 3 to 5 times that of the chicken house, it can meet the requirements of ventilation and sanitation. Longitudinal ventilation is now widely used, and the exhaust vents are on both sides of the mountain wall. The spacing of the houses can be reduced to 2 to 3 times the height of the chicken house, generally 6 to 9 m.
