引言猪高致病性蓝耳病(PRRS)、口蹄疫(MFD)都属于急性、烈性、病毒性的一类猪重大传染病,往往给养猪场和养殖户带来巨大经济损失.养猪生产中,由于各养殖场饲养猪品种不一样,在发生高致病性蓝耳病、口蹄疫等疫情时往往表现出明显的品种间差异,对猪场生产成绩影响差异也大.通过临床观测发现,在猪场发生高致病性蓝耳病、口蹄疫时,黑猪相较外种猪表现出明显的抗病力.现将观测结果报道如下.
引言产肠毒大肠杆菌(ETEC)会对新生和断奶仔猪造成严重的腹泻.葛根芩连汤是治疗湿热腹泻证的经典组方,葛根素、黄芩苷、黄连素分别是葛根、黄芩和黄连的有效活性成分.本试验以猪肠道上皮细胞(PEC-J2)为研究对象,探讨葛根素、黄芩素、黄连素和香豆素对ETEC生长情况的影响,以及药物对感染ETEC的IPEC-J2细胞形态变化的调控,旨在为临床治疗断奶仔猪腹泻开发新药物.
