摘　　要：In this study, five immune traits including immunoglobulin G （IgG）, delayed-type hypersensitivity （DTH）, leukocyte counts （WBC）, total erythrocytes （RBC） and total protein in serum （TP） were measured in Tongcheng pigs, Swedish Landrace, British Large White and two three-way crossbreds of Landrace× （Large White×Tongcheng）, Large White×（Swedish Landrace×Tongcheng）. Tongcheng pigs had the highest values of IgG （45.04 mg/mL）,DTH （8.87mm）,RBC (7.05×1012/L) and TP （66.69 g/L） among these five pig populations. RBC had positive heterosis in these studied pigs and other four immune traits had negative heterosis. There were significantly positive correlation between IgG and DTH （r=0.33, P<0.01）, IgG and TP （r=0.27, P<0.01）, DTH and TP （r=0.25, P<0.01）.In this study, five immune traits including immunoglobulin G (IgG), delayed-type hypersensitivity (DTH), leukocyte counts (WBC), total erythrocytes (RBC) and total protein in serum (TP) were measured in Tongcheng pigs, Swedish Landrace, British Large White and two three-way crossbreds of Landrace× (Large White×Tongcheng), Large White×(Swedish Landrace×Tongcheng).
