Outline of Final Research Achievements |
The perinatal transmission of bovine leukemia virus (BLV) plays a critical role in the spread and persistence of BLV infection in cattle herds. The purpose of this study was to examine the frequency of perinatal infections and to investigate some risk factors associated with infection. 18.6% were infected with BLV. Maternal viral load was significantly correlated with the frequency of perinatal infection, and more than 40% of newborn calves born to dams with high viral loads were infected with BLV. The results of this study could contribute towards developing effective eradication programmes by providing necessary data for replacement of breeding cow in the field.
