The microclimate of the pig house should be stable and not affected by changes in external temperature. Therefore, pig houses should be equipped with some pig heating equipment for heating and ventilation to ensure the normal and healthy growth and production of the pigs. Pay attention to the environmental sanitation in the pig house, and timely disinfect the small pig trough, automatic feeding trough, sow trough and other equipment.
Pig house heating is divided into two types: central heating and local heating. Central heating generates heat medium from a central heating device, and then transports the heat medium to the radiator in the pig house through the pipeline to warm the air in the pig house and maintain the proper temperature in the pig house. Local heating has hot water heating floor, electric heating plate, infrared light and so on.
Fans suitable for use on pig farms are mostly large diameter, low speed, low power fans. This type of fan has a large amount of ventilation, low noise, low power consumption and durability.
Ventilation and ventilation should pay attention to the following problems: avoid ventilation and short circuit of the fan, do not set the fan on the wall, the bottom is the through door, so that the airflow is short-circuited; if single-side exhaust is used, it should be adjacent to the pig house on both sides. The exhaust vents are located on the opposite side to prevent an exhausted turbid gas from being immediately inhaled by another pig house; try to make the airflow pass through most of the space in the pig house, especially on the ditch, so as not to cause a dead angle. The purpose of gas.
Cooling farm equipment
Although ventilation is an effective means of cooling, it can only reduce the temperature down to the ambient temperature. When the ambient temperature is greater than the maximum temperature of pig production, ventilation should be taken at the same time as ventilation. To ensure that the temperature control is within the appropriate range.
At present, the cooling system commonly used in pig farms includes wet curtain-fan cooling system, spray cooling system, spray cooling system and drip cooling system. Because the latter three cooling systems have high humidity, they are not suitable for childbirth and abortion. The wet curtain-fan cooling system is currently the most mature evaporative cooling system, and its evaporation and cooling efficiency can reach 75~90%, and it has been widely used all over the world.
On-site cleaning and disinfection equipment commonly used in pig farms includes high-pressure cleaners, flame disinfection and knapsack sprayers. The flame sterilizer works best with the disinfection of the drug. After disinfection with the drug, it is disinfected with a flame sterilizer, and the sterilization can reach more than 95%.
In order to keep the columns clean and hygienic, the modern pig farms are generally laid on the manure urinals. After the pigs urinate on the floor, the urine flows into the manure with the gap and the manure falls to the floor. In the above, after it is stepped on, it automatically falls into the dung ditch below, so as to avoid contact between pigs and feces, which is beneficial to prevent and reduce the occurrence of diseases.
According to its laying range in the pig pen, the slatted floor is divided into two types: full leakage and partial leakage. The delivery column and nursery bar raised on the high bed should use the full leaking floor and the pig pen kept on the ground. A partial leaking floor is generally used. The pig pool area is the floor of the manure, while the feeding and rest areas are solid ground.
