The study of animal diseases increases the relevance of the livestock industry, which is the main leading component of the strategy for the development of agriculture in Azerbaijan. An important roleour country. Their research is critical in the implementation of measures to combat rotavirus and coronavirus infections in infant calves. The primary goal of this study was to investigate the seasonal dynamics of accompanying diarrhea in calves caused by rotavirus and coronavirus infection. The research was carried out on farms located in the northwestern region of the Azerbaijan republic. Fecal samples were used as material and tested by chromatographic immunoassay for the qualitative detection of rotavirus and coronavirus antigen. The study revealed that the clinical signs of diarrhea in calves caused by rotavirus and coronavirus infections in farms located in the northwest region of the country are relatively similar. However, there was a relatively higher incidence of rotovirus infection, and mortality relative to coronavirus was at a lower level. The occurrence of secondary pneumonia in patients with coronavirus was noted as one of the main clinical signs. The study showed that the trend of infection and death from both diseases changes in different seasons of the year, which from season to season and, as a result, becoming massive causes serious damage to farms, becoming widespread in spring, autumn, and winter.
