    ..Interspecies transmission of BDV between sheep and cattle occurs regularly, but BDV in cattle appears to be of minor general importance. Nevertheless, BDV outbreaks at farm or local level can be very costly. ..

    ..Thus, it appears that the calves of the two production labels did not suffer obvious stress. This finding notwithstanding, all veal calves deserve to be reared under optimised animal-appropriate welfare conditions. ..

    ..In the SNT, all cows had distinctly positive titres against BD virus. Therefore, BD virus is readily transmitted by infected semen, but none of the cows conceived, most likely because of poor semen quality. ..

    ..The findings showed that cows inseminated with BDV-infected semen seroconverted and fetuses thus produced were not persistently infected. Transmission of BDV to cattle through infected semen, therefore, seems to be of minor importance. ..
