母猪猪瘟、口蹄疫血清抗体与乳中母源抗体的相关性分析及其免疫程序制定

Correlative analysis of sow fever、aftosa serum antibody and maternal antibody and the establishment of its immune programme

本试验采用不同的免疫时间、剂量和次数对同期后备母猪进行免疫,发现母猪分娩当天血清抗体水平随着免疫次数和免疫剂量的增加而增大;免疫时间不影响母猪的血清抗体水平,但在妊娠期进行猪瘟疫苗免疫的母猪的分娩率低于空怀期免疫的母猪;分娩当天乳清中的猪瘟、口蹄疫母源抗体与血清抗体呈强相关,其相关系数为0.9863和0.6709。同时,依据试验结果确定了凉山州规模化猪场母猪的免疫程序。

This experiment actualized immunization on the sows in the same period with different time, dosage and ＇number of times. It was found that the serum antibody inoreased with the enhance of dosage and number of times, the time of immunizaiton had no influence on the efficiency of serum antibody, but the parturition rate of sows, which immunized with sow fever vaccine in gestation period were lower than that of the nonpregnant period immune; the sow fever and aftosa whey antibody were strongly relevant to serum antibody on the parturition day, and the related coefficients were 0.986 3 and 0.670 9. Meanwhile, the sow fever and aftosa immune programme of Liangshan prefecture was established based on the experiment results.
