摘要 应用正向间接血凝试验检测来自6 个省( 市) 的44 个规模化猪场共754 份血清中的猪瘟抗体水平,其中331 份猪瘟血清抗体低于或等于1 8,占44.16% ,低于临界保护线,421 份血清的抗体水平大于或等于116,占55.84% ,可视为免疫合格;母猪、育肥猪和仔猪的免疫合格率分别为66.7% 、37.96% 、22.02 % 。母猪、育肥猪、仔猪血清中猪瘟抗体为零的百分比和份数分别为7 .26 %(32/441)、15.32% (21/137) 、33.03% (36/109) ,免疫效果最差的是仔猪。用正向间接红细胞凝集试验检测310 份血清的口蹄疫抗体效价,其中78.39% 的血清抗体水平低于或等于164 ,仅有21.61% 的血清抗体大于或等于1 128,达到临界保护线。中猪、仔猪、母猪的抗体水平低于1 128 的比例分别为93.75% 、92.59 % 、62.42% 。用血凝抑制试验检测了来自5 个猪场的203 份细小病毒血清抗体。猪场阳性率为100% ,猪只阳性率为79.31% ,其中母猪、仔猪、中猪的抗体阳性率分别为90.65% 、73.33% 、60.78% 。 The serum samples from 44 intensive pig farms of 6 province were teasted for antibodies to hog cholera, porcine parvovirus and foot_and_mouth disease. Among 754 Serum samples for hog chloera,only 55.84%checked sera antibody titers were ≥ 116 which were regarded as threshold of protective level. The antibody titers over the protective threshold in sows, growing pigs and piglets were 66.7%, 37.98% and 22.02%, respectively. Negative serum antibody against Hog Cholera in sows, growing pigs and piglets were 8.89%(32/441), 15.32% (21/137)and 33.3(36/109)respectively. By indirect Hemagglutination assay, the antibody in 310 serum samples against O type of the foot_and_mouth disease was detected. The antibody titer ≤164 or≥1128 were 78.39% or 21.61% respectively. The growing pigs, piglets and sows with immunization failure were 93.75%,92.59% and 62.42% respectively. With Hemagglutination_Inhibitation test, the antibody against porcine parvovirus(PPV)in 203 serum samples from 5 pig farms were also checked. All the pig farms were PPV positive. The positive rate of PPV antibody in sows, piglets and growing pigs were 90.65%, 73.33% and 60.78% respectively.
