Serum concentrations of immunoglobulins and cortisol around parturition in clinically healthy sows and sows with postpartum dysgalactia syndrome (PDS)



This study aimed to determine the profile of immunoglobulins and cortisol concentrations in serum around the periparturient period in sows suffering from postpartum dysgalactia syndrome (PDS) and in healthy sows.

Material and Methods

A total of 45 sows with lactation impairment (Group PDS) and 58 clinically healthy sows with a physiological peripartum period (Group H) were subjected to a serological test (ELISA) for measurement of serum immunoglobulins (IgG, IgM, and IgA) and cortisol concentration.


The serum contents of IgG, IgM and IgA had highly similar profiles in PDS-affected sows and healthy ones. A significantly higher concentration of IgG at 28 and 14 days ante partum compared to days 3 and 7 post partum was only observed in Group H. The mean cortisol content remained at a highly similar level throughout the entire experiment in both groups.


The results of the study indicate that lactation impairment such as PDS did not influence the immunoglobulin or cortisol concentration in sow serum.
