Abstract: This study aimed to determine the current status and epidemiological characteristics of beef cattle viral diarrheal pathogen infection in Ningxia, and to provide scientific basis for the prevention and control of bovine diarrheal disease. In this study, 293 beef cattle swabs in Ningxia were detected and genetically analyzed by RT-PCR for bovine viral diarrhea virus (BVDV), bovine coronavirus (BCoV), bovine rotavirus (BRV), bovine norovirus (BNoV), bovine astrovirus (BAstV), and analyzed their genetic evolution. The Studies showed that diarrhoeal virus infection and mixed infection were prevalent in beef cattle; The infection and mixed infection of beef cattle diarrhea virus in free-range breeding mode were more serious than those in large-scale breeding. Viral diarrhea varied significantly between different regions and viruses; Genetic evolution analysis showed that the BVDV epidemic strain in Ningxia was subtype 1e, the BRV epidemic strain was G1 subtype, the BNoV epidemic strain was GIII.2, and the BCoV epidemic strain was closely related to the genetic evolution of the French strain. The results showed that diarrheal virus infection was widespread in beef cattle in Ningxia, which was different between different breeding modes, different regions and different viruses, and the mixed infection was serious.

Key words: beef cattle, diarrhea-related viruses, RT-PCR detection, genetic evolution analysis
