Table 1.
Levels of anti-bovine rotavirus (BoRV), anti-bovine coronavirus (BoCV) and anti-F5-adhesin (F5) antibodies, expressed as % of light inhibition measured by competitive ELISA, on D0, D21, D42 and calving time (dams’ sera), in the colostra, and in calves’ sera. Data are presented as median (min; max) and mean.
