Look here, do you know the techniques for cooling pigs and disinfecting pig farms during the hot season?

High temperature in summer, bacteria are also easy to breed, for the majority of pig farmers to do a good job of disinfection and cooling is also very important. So how to cool pigs in summer? What are the disinfection techniques of pig farms?

First, among domestic animals, pigs have the worst thermoregulation ability. When the temperature rises to 30-32 ℃, the rectal temperature of pigs begins to rise. When the temperature rises to 35 ℃ and the relative humidity exceeds 65%, if the duration is prolonged, the pig can't stand it. When the rectal temperature rises to 40 ℃, it is close to the dangerous limit. As the pig's subcutaneous fat is thick, sweat glands are extremely underdeveloped, a large amount of body heat can not be dissipated. When the temperature rises close to the body temperature, the pig can not adapt, making the cardiovascular system overburdened, even exhaustion, coma, and finally the heat pole death; in addition, high temperature leads to the disorder of metabolic process and endocrine function in the body, resulting in a series of adverse reactions: loss of appetite, sharp decrease in food intake, resulting in insufficient nutrition intake, sharp decline in pig physique, weight gain or weight loss, thus affecting production efficiency. In order to safely survive the high temperature season and ensure the normal production of pigs, here are several simple ways to cool pigs, which are suitable for small-scale farms.

1. Homemade spray tube. A soft plastic water pipe with a diameter of 2-3 cm is used to run through the other end of the pig house from one end above the pigsty, and the middle is supported and fixed by iron wire and iron frame. the pipe wall can be pierced all over the small hole with a coarse injection needle, and the water pipe is connected to the pressurized tap. In the high temperature season, once every 3 hours, each time for 30 minutes, the small water column evenly erupts to form a fog, which makes the air in the pig body, the ground and the pen slightly moist and cooled slowly. If you insist on using it, you will see that the pig body is clean and shiny, the ground is clean, and there is little dust in the air. After spraying, the pig appetite is exuberant, and the hottest time at noon can lie down quietly.

two。 Self-made drip: suitable for sow limited pen pig house.

A rigid plastic tube of 2Mel 3cm in diameter was used to collude the whole pigsty from above the head and neck of the sow. the pipe wall only made a small hole in the upper part of the head and neck of each sow, the hose was connected to the faucet, and the water from the drip mouth was dripping on the neck and shoulder of the sow. The dripping orifice must be close to the sow, but the sow can not bite the hose, and the dripping water will not spill on the suckling piglets.

3. Connect the hose with the tap and shower the pig directly.

Second, disinfection in high temperature season is to kill pathogenic microorganisms, is an important epidemic prevention measure to prevent the invasion and epidemic of animal diseases, and is an important link that can not be ignored in pig production. The hot and humid season in summer is the season of frequent occurrence of infectious diseases in pigs. In order to prevent the occurrence of infectious diseases, we must do a good job in disinfection and disinfection of sources. The scope and methods of disinfection in pig farms are as follows:

1. Pig farm disinfection: a disinfection pool is set up at the entrance of the pig farm and pig house, and the disinfection solution is put into the pig farm and pig house to disinfect the vehicles and foreign personnel entering the pig farm and pig house. The disinfection solution in the disinfection pool should be changed regularly to ensure the disinfection effect.

two。 Pig house disinfection: you can first spray the ground with disinfectant, clean it thoroughly, disinfect the removed dirt according to feces, and then spray the ceiling, walls, fence, doors and windows, feeding trough, floor, utensils and doorway floor evenly with disinfectant.

3. Disinfection of utensils: drinking fountains and troughs should be often brushed with clean water and washed with disinfectant once a week. Pig disinfection can prevent the occurrence of respiratory diseases in pigs and kill planktonic microorganisms in the air in the pigsty. During the onset of the disease, the pig was sprayed twice a day.

4. Sports ground disinfection: the sports ground should be regularly cleaned, removed feces, scoured regularly, and sprayed with disinfectant solution.

5. Fecal disinfection: feces are concentrated in fermentation and disinfection, there are fermentation pool method and manure stacking method. The fermentation pool method pours the feces and mat grass that are cleared every day, and the accumulation should be loose. When it is full, it is covered with a layer of healthy pig feces or hay, plus a layer of soil is sealed and used as fertilizer after a month of fermentation. The dung heap method dug down 20 cm ~ 30 cm deep in the place where the feces were piled, first put a layer of dry dung or weeds, add more bedding grass or weeds to the thin dung, and put a layer of mud on the outside of the dung pile, which can achieve the purpose of disinfection after fermentation for a month.

6. Breeding staff disinfection: breeding staff to change clothes at work, after ultraviolet disinfection in the disinfection room before entering the field, hands contact with pigs is the main vector of disease transmission, so often use disinfectant to wash hands.
