First, the incidence On December 30, 2008, a large number of pigs from Jianchang visited our department. The livestock owner said: “He has kept more than 50 breeds of Duroc sows, gilts over 40, and boars 7 (including outsiders). 4), finishing pigs more than 200, totaling more than 300 heads. A month ago after the pigs were transferred to the new pig house, found that the sow abnormal, do not like to eat, began to mistakenly believe that the stress response caused by the group, There was no improvement in injection and injection, and some sows also experienced circling and premature birth, but the yield of piglets was normal.After two days, the piglets began to nap and did not eat milk, and one week later, the whole litter of piglets died and several litters were produced. There were stillborn, weak, and mummified fetuses, and only 200 piglets were produced in the 11th, 12th and 12th months of 2008. None of them survived, and the mortality rate reached 100%. Second, the clinical situation Pigs do not eat, mentally depressed, lethargy, constipation, pregnant sows appear premature, miscarriage, weak, stillbirths, mummy, neonatal pig mortality rate of up to 100%, outsourcing species of boar has a head with two hair blisters, black purple. Third, pathological necropsy 4 piglets 2-15 days old were necropsy and 2 fetuses were stillborn. There is no characteristic change in fetal eye appearance of stillbirth fetuses. Some mummified fetuses are brown, and the abdomen has pale yellow effusions. Some fetuses and stillbirths have subcutaneous edema and pericardial effusion. Death-fed piglets had eyelid edema, subcutaneous edema, lymphadenopathy, pericardial effusion, liver jaundice, gastric mucosa, intestinal mucosal bleeding, pulmonary congestion and edema, and enhanced lung texture. Fourth, diagnosis According to the incidence of pigs, clinical symptoms, necropsy and other characteristics, suspected porcine reproductive disorders and respiratory syndrome. Subsequently, 34 reproducible sow blood samples were collected and serum was separated. Using Beijing Wanger Biotechnology Co., Ltd. PRRS diagnostic kit, 32 were positive and 2 were negative by enzyme-linked immunosorbent assay (ELISA). The positive rate reached 94%. At the same time, the brucellosis test tube agglutination test was negative, and the collection of the kidney for swine fever antibody test was negative. Aseptically, the heart, liver and spleen were used for bacterial isolation and culture without bacterial growth. According to the laboratory test results, it was further confirmed as Porcine Reproductive Disorders and Respiratory Syndrome (PRRS). V. Control Measures 1. There is still no effective method for the prevention and treatment of PRRS. In order to control the incidence of this disease, pigs should be isolated as early as possible, sick pigs should be set up and putative health groups should be set up, closed isolation and rearing should be carried out, the isolation of the delivery room should be implemented, and the suckling piglets should be weaned as soon as possible. Finishing pigs are best all-in, all-out and thoroughly sterilized after slaughter. 2. Sick pigs diagnosed by serological examination, adopting isolation and feeding, feeding high-energy feed to sick pigs, and enough electrolytes, aspirin before sow production, preventing secondary infection with antibiotics, and simultaneously Treated with a miscarriage Chinese herbal medicine. Strengthen feeding and management, and give adequate nutrition so that it can quickly return to health. 3. Strengthen the prevention and disinfection of the environment and pens. Disinfect the environment and sheds alternately with 2% caustic soda solution or double-chain quaternary iodine salt iodine preparations. Padding aisles and wall roots with white ash 2-3 times a week. . Sixth, summary and experience 1. This site has not been immunized with PRRS vaccine. Testing of antibodies is one of the important methods. PRRS antibody was detected using Beijing Wanger Co., Ltd. PRRS enzyme-linked immunosorbent assay kit. 32 PRRS antibodies were detected in 34 samples and 2 were negative. This shows that the herd is infected with the PRRS virus. 2. After the onset of the pig herd, due to the accurate diagnosis, effective prevention measures were taken in time and the epidemic was quickly controlled. 3, do not purchase pigs out of stock if you need to isolate feeding, through the serological test negative and then retained. 4. At present, there are no effective drugs and special effects vaccines in China to prevent and treat PRRS. Symptomatic treatment with antibiotics, antiviral drugs and Chinese herbal medicine also has a certain effect. 5. It has been proved through practice that sows who are rehabilitated can continue breeding and breeding, and that gilts can be immunized with short-term contact with infected pigs. With the continued coverage of the blue ear disease in various parts of the country and the continuous deepening of the experts' research on this disease, the city's grassroots veterinary stations can also use the enzyme-linked immunosorbent assay (ELISA) for pigs with suspected blue ear disease. We quickly and accurately diagnosed and effectively controlled the occurrence of blue ear disease in our region and surrounding areas. The clinical diagnosis of blue ear disease in a pig farm is reported as follows: First, the incidence On December 30, 2008, a large number of pigs from Jianchang visited our department.
