Neutralizing anti-CPB antibody titers in gilts and their piglets using an adapted vaccination scheme. Group 1.1: standard vaccination scheme vaccine 1; Group 1.2: adapted vaccination scheme vaccine 1; Group 2.1: standard vaccination scheme vaccine 2; Group 2.2: standard vaccination scheme vaccine 2. a. Antibody titers in serum samples of gilts. Serum antibody titers of gilts at time of farrowing (T3) from groups with adapted vaccination scheme (1.2 and 2.2) were significantly higher compared to the standard scheme using the identical vaccine (1.1 and 2.1). (* = p < 0.05; ** = p < 0.01). ANOVA, Tukey-Kramer Multiple-Comparison Test. b. Antibody titers in colostrum samples of gilts. Colostral antibody titers of gilts from group 1.2 with the adapted vaccination scheme were significantly higher compared to the standard scheme using the identical vaccine (1.1) (** = p < 0.01). The elevation of antibody titers in group 2.2 was statistically non-significant compared to group 2.1. There was no statistical significance between group 2.1 and 2. ANOVA, Tukey-Kramer Multiple-Comparison Test. c. Antibody titers in serum samples of piglets. Serum antibody titers of piglets from groups with the adapted vaccination scheme (1.2 and 2.2) were significantly higher compared to the standard scheme using the identical vaccine (1.1 and 2.1). (* = p < 0.05; ** = p < 0.01) ANOVA, Tukey-Kramer Multiple-Comparison Test
