Abstract: In recent years,with the expansion of dairy goat farming scale,the incidence of streptococcosis has increased significantly,causing severe economic losses to the industry. Based on etiological analysis and prevention practices,this study systematically investigated the pathogenic characteristics, epidemiological patterns, and diagnostic methods of streptococcosis in dairy goats. The results indicate that the disease is primarily caused by β-hemolytic Streptococcus （S. equi subsp. zooepidemicus）, with a high incidence during winter and spring, and clinical manifestations including high fever, joint swelling, and visceral lesions. Laboratory diagnostics （e.g.,PCR）enable accurate pathogen detection. For prevention and control, a strategy of prevention-first, integrated management was proposed, including improved feeding practices, regular immunization （recommending streptococcal vaccines in winter and spring）,scientific medication （e.g.,penicillin combined with traditional Chinese medicine）,and the establishment of an epidemic monitoring system. Practical applications demonstrated that comprehensive implementation of these measures reduced the incidence rate by 30%,significantly mitigating farming losses. This study provided theoretical and practical insights for the scientific prevention and control of streptococcosis in dairy goats,contributing to the sustainable development of the dairy goat industry.
