| 提要文摘： | logical anatomy. The results showed that the positive rate of CSFV, PRV and SIV was 0%, that of PRRSV was 8.75%（7/80）, and that of PCV-2 was 7.5%（6/80）. The positive rate of CSFV antibody was higher than 95%, and the mean value was higher than 75%. PRRS not immune, at various stages in different proportions of positive rate, blue ear phased active, positive rate is higher than 60% of phase 1-12 weeks for the boar, lactation, and 20 to 22 weeks, S/P value higher than 2.5 mainly concentrated in lactation, the proportion of 1 to 10 weeks of piglets, the highest average 3-6 weeks, average more than 1.5, the pseudo gE antibody all negative, pseudo gB antibody positive rate were 100%, swine pseudo crazy average below 0.2 gB antibody, piglet pseudo crPorcine respiratory disease complex (PRDC) is a kind of porcine respiratory disease caused by multiple pathogens and factors, which has caused huge economic losses in the pig industry. In order to understand the main causes of respiratory syndrome in a pig farm in Yunnan province and to provide scientific guidance for the comprehensive prevention and control of respiratory diseases in the farm; In this study, 80 clinical samples were examined by fluorescence quantitative PCR, and 200 serum samples were examined by imported ELISA kit for serum antibody. The etiology of the respiratory syndrome in pigs in this farm was analyzed comprehensively by combining clinical symptoms and pathoazy average less than 0.5 gB of antibody, and keep high antibody to 22 weeks; The positive rate of PCV2 antibody was 100%, the piglet stage higher than 2.0 showed a typical serum infection process, and 20% of the pig population was negative for PCV2 antibody at 16 weeks. Swine flu is not immunized, the positive rate of antibodies varies greatly in different stages, and there is a typical infection process in commercial pigs. The results showed that: blue ear, cirrus type 2 and swine influenza were the main viral pathogens of swine respiratory syndrome in this field, and effective vaccine immunization, scientific immunization procedures, optimized daily management and other comprehensive measures could effectively control swine respiratory syndrome. At the same time, there may be other causes of respiratory disease syndrome in pigs in this farm, so further investigation and study are needed to provide data support for the prevention and control of respiratory disease syndrome in pigs in this farm. |
