The Epidemiological Investigation And Suggestion For Prevention And Control Of Three Animal Epidemics Diseases In Yanbian

Epidemiological investigation of Brucellosis,Pest des petits ruminants and Newcastle disease immunity in Yanbian from December 2015 to December 2016 was investigated.The objects of study refer to 379 cattle and sheep breeding farms,including 101 cattle farms and 278 sheep breeding farms,and the total of 12464 scattering raising-household,plus to 109 poultry farms or cooperatives and 12698 chicken scattering households.The results show that:1.The survey samples of Brucellosis and Pest des petits ruminants around Yanbian refer to 379 cattle and sheep breeding farms,including 101 cattle farms and 278 sheep breeding farms,and the total of 12464 scattering raising-household from December 2015 to December 2016.15 scale farms(7 cattle and 8 sheep)and 121 scattering-households(41 cattle and 80 sheep)scattering-households found the brucellosis disease.And there is 1 scattering raising-household of Pest des petits ruminants in sheep.According to the investigation in 109 chicken farms,and 12968 chicken scattering raising-household,13 chicken scattering-households were positive of Newcastle disease,accounting for 1/1000,and the immunization rate of three animal diseases were 100%,respecitvely.2.Investigation was carried out on the immunity of three epidemic diseases in different regions,seasons and different breeding methods in Yanbian.Cattle acceptability of antibody level acceptability of brucellosis in Tumen,Yanji,Hunchun,Dunhua,Helong,Longjing,Antu and Wangqing were 82.5%,85%,85.5%,90%,93%,97%.0,90% and 86% respectively.Sheep acceptability of antibody level of brucellosis in Tumen,Yanji,Hunchun,Dunhua,Helong,Longjing,Antu and Wangqing were 79.5%,87%,89.5%,84%,75.5%,95%,87% and 76.5% respectively.There was a significant difference in the cattle and sheep antibody level between the 8 different regions and the total positive level(P<0.05).Antibody level of Pest des petits ruminants in Tumen,Yanji,Hunchun,Dunhua,Helong City,Longjing City,Antu county and Wangqing County were 91%,87.5%,90%,99%,98%,97.0%.89.0%,87%,91.5%.Sheep antibody level in 8 different regions has a significant difference with total positive level(P=0.043).Chicken acceptability of antibody level of Newcastle disease in Tumen,Yanji,Hunchun,Hunchun,Dunhua,Helong City,Longjing City,Antu county and Wangqing County,96%,89.5%,92%,90.5%,96%,96.5%.93.0%,92.5% and 92.5%(P<0.05).3.The acceptability of antibody level of brucellosis and Pest des petits ruminants in different seasons were significantly different(P<0.05),and the survey of different breeding methods showed that the acceptability of antibody level of large-scale farms was far exceeding the acceptability of antibody level of scattering-households.There was no significant difference in the acceptability of antibody level of Newcastle disease in different regions,seasons and cultured-methods.According to the results of the investigation,the relevant prevention and control suggestions were put forward,which laid the foundation for reducing the occurrence and epidemic of the three kinds of animal diseases,and provided reference for the prevention and control of the three kinds of animal diseases.
