Abstract
[Objective]In order to do a good job in the prevention and control of cattle and sheep disease,the immune effect of Foot-and-Mouth Disease(FMD)and Peste des Petits Ruminants(PPR)vaccine was scientifically evaluated.[Method]ELISA method was used to detect the immune antibody in the serum of cattle and sheep collected from Kaili city from 2021 to 2023.[Result]From 2021 to 2023,the average pass rate of FMD O immune antibody of cattle in large-scale farms was 87.69%～89.31%,and the average pass rate of cattle in free-range farms was 65.91%～67.20%.The average pass rate of antibodies against FMD A in scale farm cattle was 71.15%～72.07%,and 55.91%～57.60%in free-range cattle.The average pass rate of FMD O immune antibody in scale farm sheep was 82.94%～85.56%,and the average pass rate in free-range farm households was 70.53%～72.27%.The average qualified rate of antibody against FMD A in sheep was 65.88%～67.22%,and the average qualified rate of free-range households was 53.68%～55.91%.The qualified rate of PPR vaccine antibody in large-scale sheep farms was 80.00%～81.11%,and the average qualified rate of antibody in free-range sheep was 71.05%～73.18%.[Conclusion]In Kaili City,Guizhou province,the immune effect of type O FMD of cattle and sheep was good,the immune effect of type A FMD of cattle and sheep was relatively poor,and the immune effect of type O/A FMD of sheep was good,but the immune effect of type O/A FMD of cattle and sheep was worse than that of large-scale farms,and the qualified rate of immune antibody of large-scale farms was higher than that of large-scale farms.It is necessary to strengthen the immunization and detection of FMD type A in cattle and sheep of large-scale farms and free-range households,and strengthen the immunization and effectiveness assessment of PPR in sheep of free-range households to ensure that no major animal outbreaks occur.关键词
