本试验旨在研究氧化锌( ZnO)对感染猪流行性腹泻病毒( PEDV)的新生阶段仔猪生长性能、肠道屏障功能和抗氧化能力的影响。采用完全随机区组试验设计,将24头平均体重为(2.5±0.2) kg的健康7日龄仔猪(杜×长×大)随机分为4组,分别为对照组、ZnO组、PEDV组和PEDV+ZnO组,每组6个重复,每个重复1头猪。试验期为12 d,分为感染前(第1~8天)和感染后(第9~12天) 2个阶段。ZnO组和PEDV+ZnO组每天灌服100 mg/kg BW ZnO;第9天07:00,PEDV组和PEDV+ZnO组每头仔猪灌服1 mL的PEDV溶液(含106 TCID50 ),对照组和ZnO组灌服等体积的磷酸盐缓冲溶液( PBS) 。结果表明:感染前,与对照组相比,灌服ZnO仔猪料重比( F/G)显著降...

This study was conducted to investigate the effects of zinc oxide (ZnO) on growth performance, intestinal barrier function and antioxidant capacity of neonatal piglets infected with porcine epidemic diarrhea virus (PEDV). In a completely randomized block design, twenty-four 7-day-old piglets (Duroc × Landrace × Yorkshire), with an average body weight of (2.5±0.2) kg, were randomly divided into 4 groups with 6 replicates per group and 1 pig per replicate. The groups were as follows: control group, ZnO group, PEDV group and PEDV+ZnO group. The...
