On the other hand, the difference
in the mean number of blood B cells between the
CoF and CoD groupswas about 40 000 cells/mL, a much
larger number of cells than that can be transferred as colostral
cells. Furthermore, the number of whole leukocytes
per 1 mL of blood expands about 1.5-fold
between 21 and 28 days of age (Pomorska-Mól &
Markowska-Daniel 2011), suggesting that piglets generate
and expand their own B cells in the weaning period.
