Signal proteins and steroid hormones as markers of inflammatory processes in the reproductive organs of sows

Abstract

The studies on the role of signal proteins and steroid hormones in the regulation of reproductive processes in sows in normal and pathological conditions were conducted on 20 sows included into the experiment on 110-112 days of pregnancy and on 3-4 days after farrowing divided into two groups depending on the nature of the postpartum period: the sows of the first group (n=10) were clinically healthy; the sows of the second group (n=10) were infected with endometritis and MMA. It was found that the sows with the risk of developing pathology in the reproductive organs observed the increase in the level of progesterone against the background of reduced content of estradiol-17β and cortisol with the activation of the synthesis of pro - and anti - inflammatory cytokines (before farrowing), in the postpartum period there was the increase in the level of progesterone and estradiol - 17β and the ratio of pro-and anti-inflammatory cytokines. During the resumption of sexual cycles the increase in cortisol, reducing the ratio of pro-and anti-inflammatory cytokines, indicators of which can serve as signal markers in the regulation of reproductive processes in sows in normal and pathological conditions were observed.
