Parts Of Large-scale Pig Farms In Jilin Province Vaccine Immune Antibody Level Detection And Analysis

Important prerequisite is the guarantee of long-term development for the pig disease prevention and control,which relates to the herd' s health stable.Serious hazard to farms in the country at present three types of major infectious diseases are in the development of classical swine fever(CSF),the blue-ear pig disease(PRRS)and Pseudorabies(PR).Infection of healthy pigs if these three patients with infectious diseases,high temperature,reproductive problems and other clinical symptoms appear,mass disease in pig farms will have serious economic losses.China's pig farm disease prevention,the use of vaccination,immune effects through antibody testing were evaluated.For assessment Jilin province 7 a area within scale pig field three species disease of vaccine immune situation,this research application Harbin Veterinary Institute development enzyme joint immune analysis reagents box,used ELISA method on Jilin province siping city,7 a area farms sends of 2,700 copies immune Hou Yu pig serum for classical swine fever,and pig breeding and breathing integrated levy(blue ear disease)and the pig pseudo rabies of antibody immune effect detection,according to detection results analysis Jilin province area farms immune level.The immunological antibody level of swine fever,porcine reproductive and respiratory syndrome virus and porcine pseudorabies were detected by Elisa method in seven regions,such as 2,700 serum samples in Siping City,Jilin Province.The results showed that the total positive rate of swine fever antibody level was 85.89%,Siping is the highest positive rate of 89.56%,the highest positive rate of Liaoyuan is 99.11%,the highest positive rate in Baishan 67.78%,Changchun City is the highest positive rate of 75.33%,Jilin City is the highest positive rate of 90.67%,the positive rate of white cities is 92.22%,Tonghua positive rate.is the highest 84%.The total positive rate of antibody level in porcine reproductive and respiratory syndrome virus was 69.78%,Siping is the highest positive rate of 75.33%,the highest positive rate of Liaoyuan is 88.44%,the highest positive rate in Baishan 56%,Changchun City is the highest positive rate of 50.67%,Jilin City is the highest positive rate of 91.67%,the positive rate of white cities is 50.67%,Tonghua positive rate is the highest 80%.The total positive rate of antibody level of pseudorabies was 66%,Siping is the highest positive rate of 85.78%,the highest positive rate of Liaoyuan is 95.11%,the highest positive rate in Baishan 52%,Changchun City is the highest positive rate of 53%,Jilin City is the highest positive rate of 82.67%,the positive rate of white cities is 34%,Tonghua positive rate is the highest 58%.The results show that the best vaccine immune effect is classical swine fever antibody,porcine reproductive and respiratory syndrome is moderate,porcine pseudorabies is the lowest.
