^aNo maternal antibodies: group 5 pigs. 

^bSerum: data from group 1 and group 3 pigs were pooled to examine the effects of administration of serum on total IgSC numbers. 

^cSerum + colostrum/milk: data from group 2 and group 4 pigs were pooled to examine the effects of administration of serum, colostrum, and milk on total IgSC numbers. 

^dNA, not available. 

^eValues for the different Igs are mean numbers of IgSC per 5 × 10⁵ MNC. Means in the same column at the same time point followed by different letters differ significantly (Kruskal-Wallis rank sum test [nonparametric]). 

^fPBL, peripheral blood lymphocyte. 

^gNumber of pigs euthanatized in each group at each time point.
