Seroprevalence of Infectious Bovine Rhinotracheitis in Dairy Animals with Reproductive Disorders in Uttar Pradesh, India

Abstract: Respiratory and reproductive disorders in dairy animals due to various etiological agents have led to significant economic losses to dairy industry. These losses are due to abortions, metritis, retention of placenta, repeat breeding, death of animals, loss of production and trade restrictions etc. The objectives of this cross-sectional study were to detect the seroprevalence of infectious bovine rhinotracheitis (IBR, BHV-1) in dairy animals of western parts of Uttar Pradesh, India. Anti BHV-1 antibodies were measured using a commercial ELISA kit (SYANOVIR® IBR-Ab). Blood samples were collected from a total of 134 animals of different age, gender from 8 districts. Overall individual seroprevalence was 32.84%. The study revealed that BHV-1 is comparatively more widespread in cattle (46.51%) than buffalo (35.28%). Comparison of different sex groups of animals revealed that the higher numbers of infected animals were identified in male (48.00%) than female (29.35%). The seropositivity of IBR increased with age of animals. The highest prevalence of IBR (66.67%) was observed in animals aged more than 8 years. As vaccination against IBR is not practiced in the region and higher percent positivity (>20%) in all age group of animals indicated the natural circulation of BHV-1 virus in the population. Because of less awareness on the vaccination of animals against this virus, the disease may spread rapidly. The results of present study also indicate that strict monitoring and surveillance of IBR is need of today to protect the animals from infection and further spread.
