BACKGROUND: Bovine coronavirus (BCoV) and bacterial pathogens contribute to bovine respiratory disease complex (BRDC) in young calves. However, the role of BCoV in BRDC occurrence and site-specific respiratory pathology in India remains poorly explored. AIMS: This study aimed to assess BCoV prevalence in BRDC cases. METHODS: We investigated 406 weaner calves (166 cattle, 240 buffaloes) up to ≤1 year, with respiratory distress and pulmonary lesions. RESULTS: BRDC cases exhibited 0.98% BCoV occurrence, confirmed by partial CONCLUSION: The present study implicated BCoV as a component of BRDC in India that should be considered in the diagnosis of BRDC outbreaks.
