摘要
Abstract
1059 serum samples from 40 swine farms of vaccination with PRRSV vaccine and 683 serum samples from 24 swine farms of non-vaccination with PRRSV vaccine were collected to determine antibody level of PRRSV with IDEXX PRRSV antibody ELISA Kit. Positive rate, coefficient variation (CV) and Sample/Positive (S/P) were analyzed. The result showed that in vaccinated pig farms, 883 of 1059 serum samples were positive of PRRSV antibody, average positive rate and CV were 83. 4% and 67. 1, respectively; S/P of 44 serum samples was higher than 2. 5, accounting for 4. 2%. In non-vaccinated pig farms, 290 of 683 serum samples were positive of antibody of PRRSV, average positive rate and CV were 42. 5% and 87. 4, respectively; S/P of 74 serum samples was higher than 2. 5, accounting for 10. 1 %. The results indicated that non-vaccinated pig farms have been infected by PRRSV. Average positive rate of PRRSV antibody is higher in vaccinated pig farms than in non-vaccinated pig farms. Simultaneously, CV and S/P in vaccinated pig farms decreased obviously compared to non-vaccinated pig farms. It is concluded that vaccination with PRRSV vaccine is one of better ways to control PRRS.关键词
