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.
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.
本研究旨在确定患有产后缺乳综合征（PDS）的母猪和健康母猪围产期血清中免疫球蛋白和皮质醇浓度的情况。
对45头泌乳功能受损的母猪（PDS组）和58头围产期生理状态正常的临床健康母猪（H组）进行血清学检测（ELISA），以测定血清免疫球蛋白（IgG、IgM和IgA）和皮质醇浓度。
PDS组母猪和健康母猪血清中IgG、IgM和IgA的含量分布高度相似。仅在H组中观察到，产前28天和14天的IgG浓度显著高于产后3天和7天。在整个实验过程中，两组的平均皮质醇含量保持在高度相似的水平。
研究结果表明，诸如PDS之类的泌乳功能受损并未影响母猪血清中的免疫球蛋白或皮质醇浓度。
