摘要 Objective] The passing rates of porcine reproductive and respiratory syn-drome virus (PRRSV) vaccine and classical swine fever virus (CSFV) vaccine were investigated in this paper. The PRRSV vaccine was injected in 14-d-old piglets and the CSFV vaccine was injected in 25-d-old piglets. [Method] The antibody expres-sion amounts were detected with the PRRSV antibody ELlSA detection kit and the CSFV antibody ELlSA detection kit. [Result] The antibody positive rates were 6.7%, 26.7%, 85% and 100% 3, 7, 14 and 30 d after the vaccination of PRRSV vaccine. While for the CSFV vaccine, 13%, 40%, 58.3% and 83.3% of the immune individu-als were antibody positive 3, 7, 14 and 30 d after the vaccination. [Conclusion] The PRRSV vaccine showed the lowest antibody tilter 3 d after the inoculation, but had a great vaccination effect 30 d after the inoculation. The piglets were not immune enough against viral invasion 3 d after the inoculation of CSFV vaccine. Although the antibody positive rate of PRRSV and CSFV vaccines al reached the required level by the Ministry of Agriculture (70%) 30 d after the inoculation, the vaccination of CSFV vaccine could not achieve the ideal effect of 100%. [目的]仔猪在14日龄接种蓝耳病毒疫苗,25日龄接种猪瘟疫苗,检测接种蓝耳病疫苗和猪瘟疫苗后的免疫合格率。[方法]采用猪繁殖与呼吸综合征病毒和猪瘟病毒ELISA抗体检测试剂盒检测抗体表达量。[结果]猪蓝耳病疫苗免疫3 d后,6.7%免疫个体为抗体阳性,免疫7 d后,26.7%免疫个体为抗体阳性,免疫14 d后,85%免疫个体为抗体阳性,免疫后30 d 100%免疫个体为抗体阳性;猪瘟疫苗免疫3 d后,13%免疫个体为抗体阳性,免疫7 d后,40%免疫个体为抗体阳性,免疫14 d后,58.3%免疫个体为抗体阳性,免疫30 d后,83.3%免疫个体为抗体阳性。[结论]仔猪在蓝耳病疫苗免疫3 d后抗体效价最低,30 d后免疫效果很好,接种猪瘟疫苗3 d后抗体效价最低,仔猪不足以抵抗病毒侵袭,虽然蓝耳病疫苗和猪瘟疫苗接种后30 d,抗体水平都达到了农业部规定的70%的标准,但是猪瘟疫苗免疫效果不能达到100%理想效果。
