Bovine respiratory infection is considered as most important factor of economic losses in dairy herds attributed through calf mortality and reduced performances. Most of the viral etiologies in respiratory infection go unnoticed due to supervene by secondary bacterial infection. Serological presence of antibodies reflects the distribution of infectious agents in herd(s) and may be helpful for designing the prevention strategies in future. The present study encompassed to determine the antibody seroprevalences by ELISA technique to more common viral respiratory agents like Bovine Respiratory Syncytial Virus (BRSV), Parainfluenza type-3 virus (PIV3) and Infectious Bovine Rhinotracheitis (IBR) and risk factors for animal level seropositivity in dairy animals. Herd level, animal level and zone wise risk factors were analyzed. The animal level seroprevalences rates were 27.81%, 47.06% and 38.50% for PIV3, BRSV and IBR, respectively. All the large to medium size herds had at least one seropositive viral infection irrespective to agents. Animals in large herd size, higher age group had highest odds of being seropositive to all viral agents. The co-infection with more than one virus is considerably common in tested animals and seropositivity for double and triple combination of the viral agents detected as 32.62 and 3.74% cases, respectively.
