The summer heat is a severe test for pig farmers. When the temperature of the pig house exceeds 30 ° C, pigs are prone to heat stroke, especially large pigs and sows. Therefore, doing a good job of heat prevention and cooling is one of the main tasks of pig farms in summer.
After testing, a mist spray cooling rein (one above each column) was installed in a two-row pig house 40 meters long and 13 meters wide, so that the mist spray water was fogged, and the cooling effect was very good. It is used during the day. It usually opens every half hour. The duration of each session is about 20 minutes.
At the same time, an exhaust fan is installed at one end of the pigsty for ventilation. Some time ago, when the temperature exceeded 37 ° C, the maximum temperature in the house was below 35 ° C during the day and below 30 ° C in the morning. The staff entered the barn from outside and felt visibly cool.
The mist spray cooling method is simple and convenient, which is not only suitable for large-scale pig farms, but also suitable for specialized farmers.
The key equipment is that the mister nozzle must atomize, such as fine fog, even if there is no harm to the humidity of the fermentation bed, because the water rarely falls into the filler, but is atomized in the air, absorbs the heat in the air and evaporates, and will not fall to the bed.
At the same time, adding 1% of the clarifying liquid in the mist spray water can effectively improve the microbial flora in the environment, maintain a good microecological balance, absorb the ammonia odor in the air, improve air quality, and the environment is also full of beneficial microorganisms, which is very effective in enhancing immune function for pigs, and can effectively help pigs "domestication".
Enhance resistance, obtain immune antibodies of various unknown pathogens, and enhance the immune antibody ability of known pathogens.
The operating cost of mist spray cooling is relatively low. The electricity consumption of 100 square meters is about 1 degree per day, but the benefits far outweigh this cost.
