Porcine erysipelas, also known as "fire-printing", is an acute and hot zoonotic infectious disease caused by A. sinensis, belonging to the second-class animal disease announced by the Ministry of Agriculture. The disease is characterized by worldwide distribution, mainly in pigs, and is most susceptible to sows and shelf pigs. Today, Xiaobian talks about the epidemiological characteristics, clinical symptoms and prevention measures of pig venom. 1 Popular features Pig erysipelas has no obvious seasonality, but the most common species are shelf pigs and sows of 4 to 6 months old. Pigs younger than 3 months old or 3 years old and older are less infected, and more people are infected through fresh wounds. Called "viruses". 2 clinical conditions 2.1 Acute type The acute type is characterized by sudden burst, acute passing and high death. The body temperature of the sick pig suddenly rises, the spirit is weak, the limbs are weak, the feed intake is poor, and it can only be lying; the pig neck, back and other skin have purple erythema, piglet Late squatting; sick pigs will die within 3-4 days, and those who do not die will turn into rash or chronic type. 2.2 Subacute type The sick pigs are thirsty, constipation, and the body temperature drops. After a few days, the sick pigs recover on their own, but some of the pigs deteriorate and become septic, which eventually leads to death. 2.3 chronic type Common conditions are chronic arthritis, chronic endocarditis and skin necrosis. Skin necrosis: The skin of the sick pig shows necrotic status and eventually leaves the body of the sick pig. Chronic endocarditis type: The heart of the doctor has a murmur, rapid heartbeat, arrhythmia, and shortness of breath, causing the pig to not breathe normally. In severe cases, the heart will be paralyzed, which will directly lead to the death of the sick pig. Chronic arthritis type: mainly manifested as inflammatory swelling of the joints of the extremities, stiff and painful legs, weak limbs and deformed joints. 3 Prevention and treatment measures for erysipelas 3.1 Do a good job in immunization The male and female sows are given two times of porcine erysipelas oxy-alkaline formaldehyde vaccine in the spring and autumn. When the finishing pigs are 60 days old, the pig erysipelas aluminum hydroxide formaldehyde vaccine or the pig triple vaccine is immunized once; within 20 days after breeding Sows, late-stage sows and lactating sows cannot be vaccinated. 3.2 Strengthening feeding management Strengthen the management of feeding, regularly clean the pig house, disinfect the equipment used in the farm house and pig diet; control the breeding density of the farm; manage the temperature, humidity and ventilation conditions inside the pig house; ensure the nutrition of the pig feed is comprehensive, sufficient. 3.3 Strengthening treatment For sick heavy pigs, intramuscular injection of penicillin 20,000 IU / (kg · bw) twice a day, continuous intramuscular injection for 3-5 days, after the injection of the drug, followed by taking Pueraria, realgar and forsythia. In the feed, the whole group was fed amoxicillin according to the 15 mg/(kg·bw) mixture and fed continuously for 3-5 days.
