Brucellosis,a zoonotic disease,not only severely impairs the reproductive performance of dairy cattle but also poses a significant threat to public health and safety. Autumn is a critical period for brucellosis prevention and control in dairy cattle,playing a vital role in reducing the incidence of brucellosis,enhancing the resistance of dairy cattle,and safeguarding their reproductive performance. Therefore,this paper discussed the key measures for autumn brucellosis prevention and control,including disinfection,immunization,testing and monitoring,and feeding management. It also analyzed the positive effects of autumn prevention and control in protecting the health of dairy cattle' reproductive systems,reducing the abortion rate,improving the survival quality of calves,and maintaining the reproductive stability of the herd. It is expected to provide theoretical basis and practical guidance for improving the prevention and control effect of brucellosis in dairy farms in autumn and ensuring the reproductive performance of dairy cattle.
