The Immune Effect Assessment Of Swine Fever And PRRS In Scale Pig Farms And Assessment Model Is Established

In order to improve the immune effect and reduce the incidence of CSF and HPRRS(Paper topics for PRRS is due to its abbreviation),At the same time,Set up the warming reference of CSF and HP-PRRS antibody Ievel,And to establish a systematic to evaluate immune effect by using this model can make the immune effect assessment an orderly way.This research select five scale pig farms to investigate production situation and to through the ELISA test to analysis the antibody level, Then adjusted the unreasonable of immunization programs and analyse the antibody level again after30to40days, to verify that the immune adjustment is or not reasonable. Meanwhile set up the warming reference of CSF and HP-PRRS and the immune evalution model. The last put the model into ten small scale pig farms to use to.The result indicates that (1)through the survey of five scale pig farms, Know that phenomenon of immunization time and the immune dosage are unreasonable, Blind imitation and passive;(2)We found that five scale pig farms for the detecting antibody levels were unqualified, A and B in the HP-PRRSV poisonous infection stage, The antibody of HP-PRRS of C,D and E are not qualified. the A’s CSF level in a poor game and four ohers are relatively stable;(3)After adjust the immunization programs, that the antibody level all got corresponding improvement and improved pigs health.(4)Set up the warming reference of CSF and HP-PRRS and the immune evaluation model.(5)Through the evalution model is applied to10small scale pig farms, All achieved good results, That worthy of producers for application.
