摘要
采用不同的免疫方式,对38头36~38日龄健康仔猪进行高致病性猪繁殖与呼吸综合征、猪瘟、猪口蹄疫3种疫苗进行免疫,分别于免疫前(0 d)和免疫后15、30、45、60、90 d采血进行这3种疫病抗体检测。结果发现效果最好的方法是先免疫猪瘟和口蹄疫疫苗14 d后再免疫高致病性猪繁殖与呼吸综合征疫苗;其次是猪瘟疫苗和高致病性猪繁殖与呼吸综合征疫苗分别释稀后混合为1针,口蹄疫疫苗另作1针同时分点注射;免疫效果最差的是高致病性猪繁殖与呼吸综合征、猪瘟、猪口蹄疫3种疫苗同时分3点注射。
Different vaccination protocols were taken to vaccinate thirty-eight 36-38-day-old healthy piglets with highly pathogenic porcine reproductive and respiratory syndrome (HP-PRRS), classical swine fever (CSF) and foot and mouth disease (FMD) vaccines, respectively. The antibody levels of CSFV, FMDV and PRRSV were tested on day 0, 15, 30, 45, 60 and 90 post vaccination. The highest antibody levels were detected when CSF and FMD vaccines vere used first followed by HP-PRRS vaccine 14 days later. The second choice was that CSF and HP-PRRS vaccines were mixed in one shot on one side of piglets and at the same time FMD vaccine was used on other side. The lowest antibody levels were detected when HP-PRRS, FMD and CSF vaccines were injected at the same time at three separate shots.
