Abstract
The results of a serological survey on BVDV infection carried out in 14 dairy farms from Veneto are presented. The overall seropositivity to antibodies against non-structural proteins of BVDV was 49%. Virological examinations revealed the presence of 8 persistently infected animals (PI) in 4 farms. There was a good correlation between high seroprevalence levels, especially in young animals, and the occurrence of PIFile in questo prodotto:
