Infectious Bovine Rhinotracheitis (IBR), caused by Bovine Herpesvirus Type 1 (BHV-1), is a highly contagious disease affecting cattle worldwide, with significant economic implications due to reduced productivity and trade limitations. Despite its impact, no prior seroepidemiological investigation has been conducted in Khorramabad, Iran. This study aimed to determine the seroprevalence of BHV-1 and assess potential risk factors associated with IBR infection in dairy cattle in Khorramabad. A descriptive-analytical study was carried out between December 2023 and March 2024, involving 100 non-vaccinated dairy cows aged 3 to 5 years from eight farms in north and south Khorramabad. Blood samples were analyzed using an indirect ELISA kit to detect anti-BHV-1 antibodies. Statistical analysis was performed using Chi-square tests and logistic regression. The overall seroprevalence of IBR was 59%. A significantly higher prevalence was observed in the southern region (88%) compared to the north (30%) (P<0.05). Seropositivity increased with age, with cows aged 4 and 5 years showing significantly higher infection rates (76.5% and 75%, respectively) compared to 3-year-olds (26.5%) (P<0.05).The high seroprevalence of BHV-1 in Khorramabad highlights the urgent need for preventive measures, particularly vaccination and improved herd management. Regional differences in prevalence and the strong association with age underscore the importance of targeted control strategies. This study provides foundational data for designing effective IBR surveillance and control programs in Khorramabad and similar regions.
