How to manage farms after flooding
The recent heavy rains in many places in the south caused many pig farms to sit in low places, resulting in large amounts of water and even flooding the farms. This caused a large number of pigs to die. Various wastes and garbage flowed along with the flood, causing serious pollution in pig houses, water sources and the environment. Bacteria, viruses, parasite eggs, etc. in the soil are flushed out by the flood and become a source of infection, which can easily cause pig diseases. After the flood, in order to cut off the source of infection, eradicate pathogens, and prevent and control the epidemic, strict disinfection must be adopted for pig houses, environment, water sources, appliances, vehicles, etc., and the corpses should be treated harmlessly. The vaccination and prevention of pig farms should be taken. Feed mold and other work. I. Hazards to pig farms after floods 1. Prone to infectious diseases after the floods. Due to the large temperature changes, it is most likely to cause infectious diseases such as swine fever, foot-and-mouth disease, anthrax, lung disease, E.coli disease, salmonellosis, Pasteurella and so on. Aspergillus disease is caused by feed and grassy mildew. Therefore, after the flood, the troughs, sinks, and utensils should be promptly cleaned and disinfected. Check the inventory of feeds carefully and treat moldy matters in time. Serious people should not continue to use it. There is a dung in the house. After the flood, it should be thoroughly cleaned and disinfected. After the flood, the quality of well water deteriorated and some of the pollution could not be used. In order to prevent the occurrence of epidemic diseases caused by drinking water pollution, we must pay close attention to changes in the quality of well water. Well water with shallow water source is best to be used for pigs after extracting well water for disinfection. For well water that may be contaminated by pig manure, sewage, garbage, and stolen goods, it is necessary not only to wash out the well water, but also to suspend it for a period of time after it has been used for disinfection. 2. Prevent insect-borne diseases after the flood. After the flood, insects such as flies, mosquitoes, and cockroaches are spawned in large quantities, and many diseases are increased in frequency and transmitted through blood-sucking insects such as mosquitoes and cockroaches. Such as spirocheasis, toxoplasmosis, Eperythrozoon, can be transmitted through blood sucking insects such as cockroaches, cockroaches, mosquitoes, cockroaches, etc. Spread a variety of in vitro and in vivo parasitic diseases. After the flood, the weeds inside and outside the pig farms must be cleared in time to clear the drainage system as soon as possible to avoid accumulation of water and faeces in the field after the flood. To prevent the breeding of harmful insects, high efficiency, low toxicity and safe insecticides can be used for spraying. 3, to prevent stress after the flood. After the floods, the weather was still hot and there was no wind. The air quality in the pig houses was generally poor, the humidity was high, and the air pressure was very low, which often caused discomfort to the pig farms. Under such environmental conditions, it is extremely easy to cause stress response in pigs, resulting in decreased appetite, rapid breathing, and depression of the pigs. It may even cause skin diseases such as eczema and dermatitis. Especially at noon after the flood, the sunshine is very intense and evaporation occurs. A large amount, the air is extremely sultry, there are often cases of heat stroke. It is necessary to increase the nutrient content of feed and increase the protein content to ensure the supply of protein in pig feed. In order to cool off the heat, you can add some fresh vegetables, watermelon rinds, etc. in the feed to avoid excessive drinking water and lead to body fluid metabolic disorders. When feeding, feed less frequently to prevent mildew from forming after leaving overnight. To provide adequate, clean, hygienic drinking water for pigs, and add 0.5% of Odemann A and Vitamin C to drinking water to reduce stress and enhance the body's resistance. Second, the disinfection of the environment and pigsty 1, the disinfection of the environment. First, it must be thoroughly cleaned and cleaned. For the flooded pighouses, the silted dirt, sand, excrement, garbage and various contaminants should be removed. According to a certain order of cleaning and cleaning, first from the roof, rear wall, and then the ground, from the far end of the pig house to the door, the first indoor and then outdoor gradually, leaving no dead ends. Serious and thorough cleaning and cleaning can not only eliminate most of the pathogens, but also greatly reduce the amount of organic matter such as feces and garbage, which is beneficial to chemical disinfectants. After thorough cleaning and cleaning, chemical disinfection can be performed. It is generally required to use 2 to 3 different types of disinfectant for 2 to 3 disinfections. After the environment is disinfected, a micro-environmental improver, Hushen, is sprayed to cover a large number of probiotics on the inside and outside surfaces of the livestock house to inhibit the breeding of harmful microorganisms and protect the environment after disinfection. 2, the disinfection of the pig body. The spray disinfection of pigs is relatively complete and thorough. It can not only directly kill the pathogens hidden in the piggery environment, including airborne pathogens, but also directly kill pathogens that are retained on the pig's body surface and superficial respiratory tract. It has a good preventive effect against swine fever, foot-and-mouth disease, etc. It has good preventive and therapeutic effects on bacterial diseases such as Staphylococcus suis, Eperythrozoon, and Escherichia coli. After spraying and disinfecting, re-spray of nursing homes in the livestock houses will not only improve the micro-ecological environment, but also settle dust, cool off the heat, provide humidity, purify the air, and improve the air quality of the pig house environment. 3, disinfection of various pig farm equipment. There are many kinds of equipment and supplies in pig farms, and the materials and uses of these equipment and supplies are different. Therefore, disinfection methods are also inconsistent. Tools can be fumigated with potassium permanganate. Feeding troughs, sinks, buckets, basins, etc., must first be scrubbed with 2% caustic soda and then rinsed with water; vehicles (including automobiles, four-wheelers, carts, etc.) must be sprayed. , Work clothes to be cleaned after disinfection or ultraviolet light can be used. After the flood, we must do a good job of disinfection. 4. Harmless treatment of pigs that die or die. After the floods, many pigs were swept away by floods, causing morbidity and massive deaths. Dead pigs carry a large number of pathogenic microorganisms. If it is not decontaminated in time, it will be rotted and mildewed, and it will give off a stench of odors. The germs will spread along with the water, spread around the air, and spread diseases. This will not only pollute the environment but also cause a pandemic of human and animal diseases. The simplest way to deal with dead pigs is to bury them deeply. For deep-buried areas, high-pit areas should be selected. The depth of the pit should be 2 m or more. After the body is put into the pit, sprinkle lime or disinfectant and cover it with a thick layer of soil. If possible, it can be burned. The bodies of dead pigs in floods are prohibited from being eaten or sold. Third, vaccination and drug prevention For flood-producing pig farms, a vaccination should be conducted, such as swine fever, foot-and-mouth disease, anthrax, swine lung disease, swine erysipelas, piglet paratyphoid fever, etc., and timely vaccination should be conducted to prevent the occurrence of infectious diseases. After the floods, pig farms and farmers have a particularly heavy task of preventing epidemics. They must be prepared to prevent serious illnesses after the floods and do a good job in preventing epidemics. Add 0.5% Oderman A to the diet and use it continuously for two weeks to improve the vaccine immunity and enhance the body resistance. Fourth, prevent feed moldy deterioration After the flood, the humidity is very high and the temperature is high, which is the proper environment for mold breeding. For the feed on the farm, if it is not well-prevented, it will become moldy and the pig will poison if eaten. The storeroom where the feed is stored must not be wet, and the piled feed should be higher than the ground and can be filled with red bricks or trays. For molds suspected to have been moldy, and not too severe, a mildewing agent such as 0.1-0.2% natamycin can be added to the feed. If the mold is very serious, it cannot be used as a feed to feed the pig to prevent mold poisoning. . In short, after the floods, the harm to the pig farms was great, causing environmental pollution in the pig farms, long-term soaking of dirty water, garbage, dirt and water, and pungent odors. If it is not cleared in time, it will be a major hazard to the farm. Therefore, it is necessary to timely clean the pig houses, drain the accumulated water, thoroughly sterilize, do a harmless treatment of the dead pig carcasses, do a good job of vaccination, drug prevention, and prevention of moldy feeds, so as to ensure that the pig farms can survive Difficulties, to create a good, healthy living environment for pigs.
