Fig. 1

Antibody levels by age of the examined sows. The figure depicts the distribution of the results of serological analyses visualized by violin plots. A S/P ratios by ELISA (Idexx). All sows (F1, n = 139; F2, n = 111) were examined. B Log2 titer of neutralizing antibodies (NAb) against the vaccine strain. In this case, 80 sows were examined. Young = sows of parities 1–2, n = 37; Middle-aged = sows of parities 3–6, n = 20; Old = sows of parities ≥ 7, n = 17. * p < 0.05; **p < 0.01; n.s. = non-significant differences
