2020-2022年湖南省小反刍兽疫春、秋季免疫效果评估

Evaluation on the Spring and Autumn Immune Effect of Peste des Petits Ruminants in Hunan Province during 2020 to 2022

摘要:

为掌握湖南省小反刍兽疫集中免疫效果，科学评估各市州免疫质量，2020～2022年在全省开展小反刍兽疫春、秋季免疫效果评估。结果显示：2020～2022年小反刍兽疫集中免疫的群体合格率为65.3%，个体合格率为71.0%。全省各地区小反刍兽疫免疫不平衡，个体免疫率最高的可达94.4%，最低的仅为47.5%。规模场免疫效果好于散养户。调查显示，一些散养户免疫意识较弱，存在免疫操作不规范情况。需要进一步加强对散养户的宣传和指导。

Abstract:

In order to make clear the spring and autumn immune effect of peste des petits ruminants (PPR) in Hunan Province and scientifically evaluate the immune quality of each region, the spring and autumn immune effect evaluation of PPR was carried out during 2020 to 2022. The results showed that the population qualification rate and the individual qualification rate were 65.3% and 71.0% respectively in 2020-2022. The immunity of PPR was unbalanced depending on regions of the province, with the highest individual immunization rate reaching 94.4% and the lowest only 47.5%. The immune effect of scale farm was better than freerange farm. The investigation showed that immunity awareness of some freerange farmers was weak, and therewere unscientific immunization operations. It is necessary to further strengthen the publicity and guidance of freerange farmers.
