摘要
2016年夏季,采集了国内毛皮动物主产区837份毛皮兽母兽、仔兽、免疫仔兽的血样,分离血清,检测其犬瘟热及细小病毒性肠炎抗体。结果表明:断奶后母兽犬瘟热SN抗体均值为91.6,细小病毒性肠炎HI抗体均值(log2)为10.4,抗体水平高,对两种传染病有足够保护,提供了较高的母源抗体;未免疫仔兽犬瘟热反应抗体下降较快,35 d以上仔兽犬瘟热母源抗体不足以保护仔兽,细小病毒性肠炎HI抗体值较好,对仔兽有很好保护效果;健康动物疫苗免疫后抗体上升较快,免疫后15 d,抗体均值都远高于有效保护值,可以保护动物免于发病。
Eigh hundred and thirty seven blood samples were collected from the mother, young and vaccinated animals bred for fur in the domestic fur production areas in the Summer of 2016, and the serum were separated to examine the antibodies against canine distemper（CD） and mink viral enteritis（ME）. The results showed that the antibodies with the mean CD SN 91.6 and the mean ME HI 2^10.4 from fur mother animals after weaning were high enough to defense the two infectious diseases, which provided higher maternal antibodies for young animals. Antibodies of young animals without vaccination declined fast and maternal antibodies against CD were not enough to supply immunity against the disease for the young animals born after 35 days, and ME HI antibodies were better and enough against the infection. The antibodies of healthy animals raised fast post vaccination and were high enough against the infection after vaccination for 15 days.
