低温环境对民猪免疫应答的影响
- 文献标志码:
- A
- 摘要:
- 为研究低温环境条件下免疫应答对民猪激素水平的影响，选择健康的仔猪（民猪及大白猪），达到21日龄时，接种猪瘟兔化弱毒疫苗，达到48日龄时，检测的猪瘟抗体，根据结果选择体重、抗体水平接近的仔猪20头，大白猪仔猪20头，随机分组,分别为低温环境两组（1组、2组）及适温环境两组（3组、4组），其中1组为10头民猪，2组为10头大白猪，3组为10头民猪，4组为10头大白猪。试验期14 d，以猪瘟疫苗接种作为免疫应答手段，用ELISA方法对血清中方法检测干扰素-α（IFN-α）、白细胞介素6（IL-6）、猪瘟抗体（CSF）含量进行测定。结果表明：2组的IFN-α含量在14 d时、IL-6含量在7 d和14 d时、CSF在14 d时显著低于其他3组（P<0.05）。说明低温环境对民猪免疫应答的影响程度低于大白猪，民猪的抗冷应激能力强于大白猪。
