羊口蹄疫免疫方法及效果研究

通过对陕西省绥德县15乡镇15户养羊户饲养的未免疫4~7月龄羊150只,分别进行口蹄疫灭活疫苗一次免疫（150只）、加强免疫（其中30只）,并开展抗体检测,结果发现一次免疫抗体合格率为55.33%,加强免疫合格率为93.33%。试验表明,加强免疫后羊免疫抗体合格率可以得到保证,并根据免疫试验进行分析,为今后羊口蹄疫科学免疫提出合理的建议。

Comparison of Immune Effect of Different Immune Methods for Foot and Mouth Disease of Sheep

A total of 150 non-immunized 4-7 months old sheep from 15 raising households of Suide County of Shannxi Province were included in this study to compare the immune effect of different immune methods for foot and mouth disease. All of the selected sheep were singly vaccinated with inactivated foot and mouth disease vaccine. Subsequently, 30 of the vaccinated sheep were subjected to booster immunization with the same vaccine. The antibody against foot and mouth disease virus in singly immunized and booster immunized sheep were determined. The results revealed that the qualified rate of antibody level in singly immunized sheep was 55.33% and that of booster immunized sheep was 93.33%. It was indicated that the immune effect of booster immunization method is superior to that of single immunization.
