It's possible, but you have to be careful with the method and not implement it blindly.
Specific method:
1. After simple filtration of the biogas slurry in the secondary anaerobic fermentation tank, use a sewage pump to flush the pigsty. When rinsing, the water will be. big. It is short. Pigs are used to drinking biogas slurry and playing. Each round takes less than a minute. Finally, the biogas slurry and pig manure return to the first level anaerobic fermentation. reservoir.
2. Use biogas to heat the water to 50 degrees and flush it with high pressure. Do not use water below 35 degrees in winter, otherwise the pigs will suffer from emergencies and diarrhea. a fifth of conventional rinsing. Once again, each turn takes tens of seconds.
3. Use a high pressure gun to atomize and disinfect the prepared disinfectant directly.sound of one kilogram per five square meters. The temperature of the disinfectant should be 38 to 40 degrees.
Advantages: good cleaning and disinfection effects, no need for manual manure cleaning, labor saving, and the pigs are very healthy.
Disadvantages: The temperature of the pigsty should be 20-22 degrees, the ventilation effect is good, and no forced cooling is allowed.
Note:
The temperature is not sufficient and it is too cold to rinse the circle with water; ventilation is poor and drying is slow, so the circle cannot be rinsed with water; water. This method is used in large pig barns and the benefits of reducing piglet droppings are not obvious.
1. Be sure to prepare a chilling plan in advance.
Many pig farms do not prepare in advance. They only think about cooling whenthe temperature is high. high, which often fails to achieve the desired effect; the plan chosen by certain pig farms is not adapted to the operating conditions. After the installations were installed, they did not give the expected results; some problems were discovered after use and when modifications were made the high temperature season was about to end. Therefore, we recommend that pig farms install and test cooling facilities before the arrival of the high temperature season. Make sure it can be left alone after use and ready to use when needed.
Fan wet curtain cooling system
2. Be sure to pay attention to the humidity of the pigsty
Water curtains, air coolers, etc. are all used. the principle of cooling by evaporation of water, which is cconsistent with air humidity, has an excellent relationship: the cooling effect is good when the air humidity is low, but the cooling effect is poor when the air humidity is high, however, high humidity often occurs; at the same time during high temperature seasons, which greatly reduces the cooling effect. The solution is to use Yueneng water curtains to cool when the humidity is high, and at the same time use mechanical ventilation to increase the air flow in the house, to increase the pigs' feeling of coolness at the same temperature.
3. The house is not sealed during negative pressure cooling.
As the water curtain cools, a fan is used to generate negative pressure inside the house. passes through the damp curtain and the humidity is reduced. When the water in the curtain evaporates,the temperature drops, allowing cooled air to enter the house, resulting in a cooling effect, but if the house is not properly closed at the time; or the windows are not closed tightly, or the floor windows are not blocked, or the pigsty door is large. If it is open, a large amount of air will not pass through the damp curtain but will enter the house through other holes because of these; the holes have no temperature reducing function, the cooling effect will not be achieved or the effect is not ideal and the expected purpose cannot be achieved.
IV. Unreasonable use of fans
Fans can make pigs feel cool. This is something everyone knows, but only. Only when the wind blows on the pigs will they have a cool feeling. However, if a fan is installed but cannot blow onpigs, not only will there be no cooling effect, but it will also increase air circulation and bring higher temperature air outside. the house in the house, which makes the pigs cold. The temperature is higher, so if the fan setting is unreasonable, some pigs will have a cooling effect at the same time. Another part of the pigs increases the temperature, so ceiling fans are used, especially in the farrowing room. Several pigs share a ceiling fan, which often produces unsatisfactory results. Another unreasonable phenomenon is the use of fans to cool the boar building. temperature of the boar's testicles 2 to 3°C lower than body temperature, that is to say as long as the air temperature exceeds 35°C. This will impact the seed, so using fans to cool whenhe air temperature above 35°C is harmful to boars but not beneficial. Many pig farms have suffered losses in this regard.
5. Insufficient water supply
In summer, when voltage is low and water consumption is large, the water supply should be strengthened and measures such as increasing water tanks reserve and emergency preparation generators are all Large-scale pig farms should consider maintaining generators and water pumps in good condition at all times. This should also be taken into account.
6. Don't consider water temperature
People can cool off by eating iced drinks when they are hot. The same is true for pigs if they drink fresh water. are hot, they can also relieve a feeling of heat. However, many pig farms do not pay attention to circulationion of water. Especially when it is hot, the water temperature in the water pipes is close to the air temperature. It is even close to the body temperature of pigs, and pigs are animals with underdeveloped sweat glands. The cooling effect of letting cold water pass through the digestive tract will be more obvious. Therefore, in pig farms with sufficient water sources, timely draining the high temperature water in the pipes so that the pigs can drink cool water will also have a certain cooling effect.
