Respiratory disorders are major concern for dairy cattle industry. Viruses and bacteria in combination
with stress playa key role in triggering acute respiratory infections. The most important viral agents are
bovine viral diarrhoea virus (BVDV), bovine herpes virus type I (BHV-I), bovine respiratory syncytial virus
(BRSV), parainfluenza virus type 3 (PIV-3) and bovine adenovirus (BAV). This cross-sectional study was
conducted to evaluate the serological status of BYDY, BHY-I, BRSY, PIY-3 and BAY in dairy herds in
Kerman province, Iran. From June to November 2007, 181 serum samples were collected from 1-3-year-old
cattle from 15 industrial dairy farms in Kerman province using cluster sampling. The samples were tested by
commercial indirect ELISA kits. Antibodies were detected against BVDY, SHY-1, BRSV, PlY-3 and BAV
in 77.90, 30.39, 100, 100 and 1000/0 of serum samples, respectively. All farms were positive at least for one
of these viruses and antibodies against all the 5 viruses were detected in 4 (26.66%) herds among 15 dairy
farms. According to the present study, BYDY, BRSY, PIY-3 and SAY are common viruses in dairy herds in
Kerman province.
