Abstract
The aim of this study is to assess the e ects of parity number on sow reproductive
performance and the chemical and immunological composition of colostrum and immunoglobin
concentrations in the sera of the sows. Colostrum samples were collected at 0, 6 and 24 h after
the births of the first piglets from 56 sows with di erent numbers of parturitions (ranging 1–6).
The piglets born alive to primiparous sows had lower birth weights (p < 0.05) than piglets from
second and fourth parturition sows. The colostrum composition was influenced (p < 0.05) by parity
number: primiparous sows had higher concentrations of dry matter, fat, lactose and non-fat-solids.
No parity-dependent di erences were found concerning total protein amount. Colostrumcomposition
was drastically a ected (p < 0.001) by sampling time—the highest concentrations of dry matter
and protein and lowest concentrations of fat and lactose were found immediately after parturition
(0 h). The study revealed no e ect of parity (p 0.05) on the concentrations of immunoglobulins
in colostrum. The immunoglobulin with the highest level in sow serum at day 110 of gestation
was IgG, while IgA showed the lowest values and greater variability with respect to parity from
an immunological point of view. Regarding the relationship between serum Ig levels at the end
of gestation and colostrum Ig, serum IgG showed a strong correlation with colostrum IgG and
IgM, while colostrum IgG was strongly related with colostrum IgM, but not with IgA. IgA did not
correlate with any other immunoglobulin. The di erent behaviors of the immunoglobins in colostrum
were probably due to IgG coming almost exclusively from the sows’ sera, whereas IgA is mainly
synthetized by the mammary gland
