| 为了探讨猪繁殖与呼吸障碍综合症病毒（Porcine reproductive and respiratory syndrome virus，PRRSV）
CH-1R 株活疫苗对蓝耳病经典毒株JXA1 的保护效果，采用CH-1R 株活疫苗免疫14 日龄PRRSV 阴性仔猪，1 周后
攻毒，对12、21、35、49、63 日龄时的仔猪外周血中淋巴细胞亚群CD3+、CD4+、CD8+的比例和外周血中抗体进行检测。
结果表明院免疫7 d后，CD4+/lym 的比值升高，CD8+/lym 的比值降低，CD4+/CD8+的比例升高；攻毒2 周后，CH-1R 株活
疫苗免疫组仔猪CD4+/lym 和CD8+/lym 的比值均升高，并且CD4+/CD8+的比例也升高，说明CH-1R 株活疫苗对经典
毒株JXA1 可能具有保护效果。 |
| 英文摘要: |
| This experiment was conducted to investigate the technique of extracting deoxynivalenol from the
contaminated corn and effects of contaminated feed on the changes of the growth performance, blood routine, serum
biochemical indexes. A total of 10 crossbred weaner piglets with an average body weight of 7.70(依1.00) kg were randomly
assigned to 2 groups as follows: control group fed with basal diet, DON group fed with basal diet + DON. The experiment
lasted for 38 d. The results showed that, low dose of DON (2 mg/kg) in contaminated feed could reduce growth performance
of weaner piglets, and induce some changes in part of serum biochemical and blood routine indexes, but had no obvious
effect on most of indicators, and had no influence on the viscera index. |
