Abstract：To understand the immune effect of O-type foot and mouth disease(FMD)in Pamir yaks in Taxkorgan County,a total of 3 984 serum samples were randomly collected from 560 sites in 10 townships of the county.The liquid phase blocking ELISA method was used to detect the immune antibody titer of O-type FMD.The results showed that the qualified rate of immune antibodies(antibody titer≥1:128)in Pamir yaks in Taxkorgan County from 2021 to 2024 were 77.21％,91.21％,86.41％,and 88.51％respectively,with an average qualified rate of 85.72％,all meeting the standard of more than 70％required by the Ministry of Agriculture and Rural Affairs.The qualified rate in autumn was generally higher than that in spring from 2021 to 2022,and the difference was not significant after 2023.The qualified rate of immune antibodies from 2022 to 2024 was similar and extremely higher than that in 2021(P<0.01).The study indicates that the FMD immunization work of Pamir yaks in Taxkorgan County from 2021 to 2024 has achieved the expected effect.However,there is a certain degree of fluctuation in the antibody qualified rate in different years and seasons.It is necessary to continue to strengthen the construction of yak epidemic prevention system,improve the immune antibody level of yak herds,thereby enhancing the immune effect and providing a guarantee for the sustainable and healthy development of Pamir yak breeding industry.
