Abstract

The aims of this study were to investigate prevalence of BVDV infection in cattle population based on selected farms in Selangor and its interaction with possible risk factors. A total of 407 blood samples were collected from five selected Ladang Angkat of UPM and Taman Pertanian Universiti (TPU) within Selangor. Serum or plasma samples were separated from the collected blood samples and stored at -20 °C until analyses. A direct ELISA (PrioCHECK®BVDV antibody) was used to detect antibody against BVDV following the protocol given by the manufacturer. Results demonstrated that the overall prevalence of BVDV infection was 33.2% (135/407). There was a significant difference in the prevalence among individual farms; 75.9% (66/87), 26.0% (66/254), 13.3% (2/15), 2.8% (1/36), 0% (0/15), for A, E, B, C and D farm respectively. Animals grouped according to breed, age, sex, lactation and pregnancy status showed significant variation in BVDV prevalence. It was found that significantly more females (35.5%) than males (16.3%); more adults (36.7%) than young calves (15.2%), more pregnant (42.9%) than non-pregnant (31.1%); more lactating (51.1%) than non-lactating (25.8%) cows affected. According to breed, dairy Friesian-Sahiwal and Jersey crosses were the most affected while beef cattle breeds such as Kedah-Kelantan were least affected. In conclusion, the study revealed that BVDV infection are highly prevalent in cattle in Selangor and varies with farms, breed, sex, age, lactation, and pregnancy status. This study is pioneer to explore the status of BVDV infection in cattle populations in Malaysia and would help as a foundation for further investigations on BVDV.
