Four key steps in pig farm treatment after flood

1. Disinfection of environment.

First, a thorough cleaning and cleaning is required. The flooded pigsty should be cleared of silted soil, sand, feces, garbage and all kinds of dirt. Cleaning and cleaning shall be carried out in a certain order, first from the roof of the shed, the rear wall, then the ground, from the far end of the pigsty to the door, first indoors and then outdoors, leaving no dead corners. After careful and thorough cleaning and cleaning, not only can most pathogens be removed, but also the amount of organic matter such as feces and garbage can be greatly reduced, which is conducive to the role of chemical disinfectants. Chemical disinfection can be carried out after thorough cleaning and cleaning. Generally, it is required to use 2 ~3 disinfectants with different action types for 2 ~3 times of disinfection. After environment disinfection, microecological environment modifier is sprayed to make a large number of probiotics cover the inner and outer surfaces of livestock houses, inhibit the growth of harmful microorganisms and improve the environment.

2. Disinfection of pigs.

Spray disinfection of pigs is comprehensive and thorough, which can not only directly kill pathogenic microorganisms hidden in the environment of pig houses, including air, but also directly kill pathogens on pig body surface and superficial respiratory tract. It has a good preventive effect on swine fever, foot and mouth disease, and a good preventive effect on bacterial diseases such as Staphylococcus suis, Eperythrozoon, Escherichia coli, etc. After spraying disinfection, microecological environment modifier is sprayed again in the pigsty, which not only improves the microecological environment, but also settles dust, prevents heatstroke, provides humidity, purifies air and improves the air quality of pigsty environment.

3. Disinfection of all kinds of tools in pig farms.

There are many kinds of utensils and articles in pig farms. The materials and uses of these utensils and articles are different, so the disinfection methods are not consistent. Tools can be fumigated with potassium permanganate, feeding troughs, sinks, buckets and basins, etc., to be washed with 2% caustic soda first, and then washed with clean water; vehicles (including cars, four-wheeled vehicles, trolleys, etc.) to be sprayed, overalls to be cleaned after disinfection or ultraviolet light irradiation can be used. Disinfection should be done carefully after the flood.

4. Harmless treatment of pigs that die of illness or drown.

After the flood, many pigs were washed away by the flood, causing illness and a large number of deaths. Dead pigs carry a large number of pathogenic microorganisms in their bodies. If it is not treated innocuously in time, it will rot and mildew, and emit a foul smell. The bacteria will flow with the water and spread everywhere with the air, spreading diseases, not only polluting the environment, but also easily causing human and animal epidemics. The easiest way to dispose of dead pigs is to bury them deeply. Deep burial should be selected in high hillock area, pit depth of more than 2 m, after the body into the pit, sprinkle lime or disinfectant, covered with a layer of thick soil. If conditions permit, they can be burned. The carcasses of pigs killed in floods are prohibited from eating or selling. Liao Yongmin
