In recent years, the frequency of automated poultry farming equipment has become more and more high. The use of equipment to raise chickens has only two modes: raising chickens and raising chickens. There are also two modes of building a chicken house: open and closed.
The open chicken coop has doors and windows that are ventilated by natural air flow, illuminating through the natural light of the windows. The temperature and humidity in the meeting basically change with the climate change of the four seasons. The cost of chickens is low, the investment in chicken equipment is low, and the feed requirements are not strict. However, the production capacity of chicken flocks is greatly affected by the natural environment, and it is difficult to prevent epidemics.
The closed chicken is made of heat-insulating materials to build the roof and the four walls. There are no windows on all sides. The microclimate and lighting in the house can be adjusted according to the physiological functions of the chicken, so that the chicken can be periodically based on high production stability. Cattle production can also reduce the spread of foreign diseases. However, the chicken house has a higher investment in raising chickens. The problem of feeding chicken equipment is highly dependent on electricity and must require full-price feed. It is the main type of factory and mechanized chicken farming equipment.
Chicken house equipment must be mechanically ventilated. According to the flow direction of the airflow in the house, it can be divided into two types: horizontal ventilation and longitudinal ventilation. Lateral ventilation means that the direction of airflow in the house is perpendicular to the long axis of the house. Longitudinal ventilation refers to the way in which a large number of fans are concentrated in one place, so that the airflow in the house is parallel to the long axis of the house. The research practice since 1988 proves that the longitudinal ventilation effect is better, can eliminate and overcome the phenomenon of small dead angle and low wind speed in the horizontal ventilation, and how to raise the chicken equipment, how to ventilate the chicken equipment and eliminate the horizontal ventilation. The drawbacks of cross-infection.
