At present, more and more chicken farms are beginning to enter the stage of standardized breeding. In the process of standardized chicken raising, there are often many breeding problems. Among them, farming and animal husbandry fan ventilation problem is very important in standardized chicken farms. Currently, standardized chicken houses are mostly closed farming, for keeping chicken The air in the house is fresh enough, there is sufficient oxygen to discharge harmful gases and keep the environment inside the house clean. The setting of the ventilation system of the farming and animal husbandry is very important.

      Due to the unreasonable design of the house, there are often problems in the later stages of use. What should I do at this time? Proper use and control of the ventilation system is also critical and cannot be ignored. Today, Xiaobian wants to introduce some of the problems and solutions that are often encountered in modern chicken farms.

      1. Waste heat reuse

      Taboo farming and animal husbandry fan inlet fan, the small air inlet is the problem, this will The result is that the air enters a small number of rows, forming a high negative pressure and anoxic, which causes the chicken house to be stuffy. If the wind speed is fast, the chickens are susceptible to cold. In particular, the front end of the wind is less likely to form a windless area.

      2. Temperature difference in the house

      In the ventilation process, the air outlet surface can be reduced to prevent the wind from sinking, especially the end air outlet The area is such that the wind speed is accelerated and discharged as soon as possible. The length of the house is controlled within 120 meters, and the booster fan can also be added in the middle.

      3. Side fan setting

      Just as we said, in the process of ventilation construction of the chicken house, the side of the farm animal husbandry The setting of the fan is especially important. The side fan is used for insulation and ventilation. In order to prevent the ventilation of the chicks from being too large, cold stress may occur. If the house is small and the ventilation is properly handled, it is also considered that there is no side fan.

      4. The wind speed slow cooling effect is poor

      Generally, the wind speed is slow, the cooling effect is worse, there are several reasons, the air duct There are obstructions to block the wind, this man needs to avoid. Followed by the air outlet, the blades of agricultural and animal husbandry, the ash and ash are not clean, affecting the wind speed, and the rusting of the fan is not working, the belt is too loose, and the power should not be reached. Therefore, when designing the ventilation of the chicken house, it is very important to choose the regular brand of farm animal husbandry fan and daily maintenance.

      5. Somatosensory temperature and humidity

      Humidity and wind speed are critical in cooling, and high humidity and slow wind speed affect heat dissipation. In order to cool down, there must be sufficient wind speed, the ambient temperature is too high, the water temperature is high, and it is not easy to cool down. You can take the temperature of the precipitation, sunscreen, and cool down with ice bricks when needed.

      6. Nitrogen exceeds the standard

      In general, experienced breeders will affect the growth of chickens at a certain concentration of ammonia. Before the performance, you can be aware of the presence of ammonia, and ensure the ventilation of the farming and animal husbandry to keep the litter dry. The general criteria for determining the ammonia concentration in a broiler house are: 10-15 ppm: smells of ammonia; 25-35 ppm: starts to irritate the eyes; 50 ppm: the eyes of the birds are weeping, inflamed; 75 ppm: the head of the chicken is twitching .
