description | This study was conducted on two dairy farms that breed Holstein cattle in the municipality of Bragança Paulista, São Paulo. The study included 11 female calves that were one to three months old. The animals were autopsied. Tissue samples of affected organs were collected for histopathological and microbiological examination and blood was collected for serological tests. The aim of this study was to identify the main causes of death in calves of dairy cattle from the Bragantina region. Among the causes, the frequency of dysentery and respiratory diseases was similar. The samples evalulated identified a higher frequency of macroscopic and microscopic lung lesions when compared to intestinal lesions. The etiological agents associated with the diseases found were Salmonella sp., Escherichia coli, Clostridium perfringens, Pasteurella spp., syncytial virus and coronavirus, which affect the respiratory and gastrointestinal systems and can lead to septicemia and death. |
