ABSTRACT
A serological detection by employing commercial enzyme-linked immunosorbent assay (ELISA) kit to test the prevalence of BVDV(Bovine Viral Diarrhea Virus) in yaks in Hongyuan, Sichuan province, a cold climate and high altitude area of China. Totally, 516 yak serum samples were randomly got during 2012 to 2014. BVDV was found highly prevalent among the adult yaks (51.1%; 95% CI: 46.5-55.6) and calves (60.5%; 95% CI: 43.4-76.0), respectively. The prevalence of BVDV infection in 2012 to 2014 was 45.3% (95% CI: 38.6%-52.1%); 56.0% (95% CI: 49.7-62.2) and 60.5% (95% CI: 43.4-76.0), respectively with a significant difference in the three years (P<0.05). The current result reveal a growing prevalence of BVDV infection in yaks in this area.
