First, start from the source, do not let the disease enter the market 1. Do a good job of quarantine and isolation. The purchase of piglets should be done on a regular large-scale farm or purchased by neighboring farmers. If you buy piglets in the market, it is recommended that you buy them at one or two locations, so that the pigs have a high level of uniformity, a good relationship with the establishment of herds, a low transport stress, a low probability of fighting, and a similar normal flora to avoid cross-infection. The newly purchased pigs should be isolated and observed for 3 to 4 weeks and then grouped with the original pigs. The first week of new pigs should be added to the feed with some commonly used antibiotics to reduce the diseases caused by environmental stress. After 3 days of withdrawal, vaccination should be carried out according to the epidemic prevention procedures. It is recommended that all pigs purchased from the market be re-immunized regardless of their original prevention. 2. Establish a strict entry sanitization system and adopt scientific sterilization methods. Small and medium-sized farms in rural areas often ignore the role of disinfection, and some do not even have the concept of disinfection. The disinfection of people, materials, and materials is particularly important. In order to prevent the pathogens and dirt brought by the feeding and management personnel, outsiders and vehicles from entering the farm, it poses a threat to the pig farms. A wide and deep disinfecting pool and hand washing should be installed at the gate of the farm. Disinfection pots, in and out personnel and vehicles coming out of the house must be sterilized before entering the market. Second, strengthen management, reduce the incidence of incentives 1, to provide high-quality full-priced feed, improve the pig's resistance. Regardless of the market conditions of pigs, the nutritional needs of pigs must be ensured and the nutritional formula provided by feed mills should not be changed easily. A growing number of studies have shown that peptide preparations can improve the body's immune capacity and production performance, and enhance disease resistance and anti-stress ability. 0.2% of biologically active peptides can be added to the feed, which can effectively overcome piglet weaning stress, improve immunity, and ensure sufficient clean drinking water. 2, control the appropriate temperature, reduce the harmful gas in the pigs. The ventilation of the pig house should be strengthened to maintain the freshness of the air in the house and reduce the concentration of ammonia gas and hydrogen sulfide gas, thereby reducing the stimulation of the respiratory tract and reducing the occurrence of respiratory diseases. At the same time, pay attention to control the temperature inside the house, so that the summer heatstroke cooling, winter cold insulation, as far as possible so that the temperature difference between morning and evening not too much. Branch and nursing homes require small environmental insulation and large-scale ventilation. Third, scientific immunity and medication, improve resistance to disease Immunoprophylaxis is the artificial inoculation of animals with a vaccine that causes the animals to have a special resistance to the disease. Injecting vaccines must follow scientific immunization procedures and use effective vaccines. Pig farms and farmers can work with local veterinarians and experts in the prevention and control departments or scientific research departments, according to the actual conditions of the season, the surrounding environment, the current status of the farm, the level of rearing, etc. The situation develops an immunization program suitable for this field. There is no universal immunization program that can be used on all pig farms. Drug prevention (pharmaceutical care) is a supplement and emergency measure for vaccine prevention. For example, when the climate becomes cold in the autumn, anti-respiratory drugs are added to the feed, anti-diarrheal drugs are added in the cold and humid winter, sows are used for antipyretic and mastitis drugs before and after the birth, newborn piglets, new piglets, and weaned piglets The use of drug prophylaxis by both swine and subgroup pigs has received very good results. The use of drugs should also pay attention to incompatibility and compliance with withdrawal requirements. Regardless of drinking water or spices, require uniform concentration, drinking water should be stopped before the medication 2 to 4 hours, the dose should be sufficient, but do not blindly increase the amount, pay attention to ensure that the course of treatment, general drug prophylaxis in 5 to 7 days, medication should be Pay close attention to the status of the pigs and find that the abnormalities are dealt with promptly. Fourth, early diagnosis, create opportunities for cure As the early symptoms of swine disease are not obvious, careful observation is required, and the working time of the breeders should be allocated scientifically. The pigs and piglets personnel should be allocated 20% of the time for feeding and cleaning, and 80% of the time Observe the pigs and find abnormalities. The diagnosis of swine diseases includes epidemiological investigation, clinical symptom analysis, pathological anatomy and histopathological diagnosis, immunological diagnosis, therapeutic effect test, laboratory etiology and serological diagnosis. We can reduce the scope of suspicion by suspecting or eliminating certain diseases based on the surrounding epidemic situation and immune prevention. Once the disease is diagnosed, it is necessary to use sensitive drugs for treatment. If delays can cause the disease to worsen or the pigs fail, it will be difficult to cure.

3, rational grouping, adjust the density. Pigs should not be too large, and the number of pigs in each pen should not exceed 15 as many as possible; try to reduce the number of times that the herd is transferred and mixed; reduce the stress factors, so that the pigs live in a comfortable, quiet, dry, Hygienic and clean environment.
