Table 3.
Levels of anti-bovine rotavirus (BoRV), anti-bovine coronavirus (BoCV) and anti-F5-adhesin (F5) antibodies in the colostrum, expressed as % of light inhibition measured by competitive ELISA, depending on the vaccination-calving interval (VCI). Data are presented as median (min; max); n = number of animals with the indicated VCI (± 3–4 days); and the % of animals with a PI ≥ 95% in brackets.
| VCI ≤ 3 weeks* | 4 ≤ VCI ≤ 6 weeks | 7 ≤ VCI ≤ 9 weeks | VCI ≥ 10 weeks* | ||
