摘要 内毒素蓄积是规模化猪场猪群亚健康的主要原因之一,其使猪群呈现免疫抑制状态。那么长期内毒素蓄积是如何影响猪群的免疫状态?试验主要选择了生物安全执行较好和较差的2个不同集约化猪场,应用ELISA方法分析各个生理阶段猪群血液内毒素、sIgA和炎性因子水平。结果发现严格执行生物安全的猪场(猪场-I),各个生理阶段的猪群体内蓄积内毒素的含量,显著低于执行力较差的猪场(猪场-II);而猪场-I各个生理阶段猪群血液sIgA含量,显著高于猪场-II的猪群;猪场-I各个生理阶段猪群血液中部分促炎因子含量,显著高于猪场-II的猪群。由此得出生物安全执行力较好的猪场可自身净化内毒素,而生物安全执行力较差猪场,随着饲养时间的延长,猪只体内蓄积的内毒素越多,免疫性能越低下,引发猪群处于亚健康状态。
