Abstract
The aim of study was histological evaluation of oviduct and uterus mucosa in case of cystic ovarian degeneration in sows. Materials for evaluations were received after slaughtering of 294 sows at age of 2-5 years. Sows were eliminated breeding and culled due to reproduction disorders: anoestrus after weaning of piglets, return of estrus, small litters and due to age, number of birth, bad condition after lactation. 20 sows (6,8%) had cysts on ovaries. Histological investigations were conducted on reproductive organs of sows with ovarian cysts. Sows were divided onto two groups: 1. with polycystic ovaries (12 sows), 2. with simple cyst (8 sows) occurred unilaterally (3 sows) or bilaterally (5 sows).In our studies we noted different kids of ovarian cysts and structural changes in ovarian cortex like decreasing numbers of ovarian follicules of all generations, increasing of follicular atresia. We compared the state of oviduct and uterus mucosa in case of polycystic ovaries with the histological changes in these tissues when single cysts were present on the ovaries. The single follicular cysts aren't accompanied with important changes in reproductive system. In case of polycystic ovaries the presence of cyst is connected with occurrence of morphological changes in endothelium of oviduct and uterus which would have been a reason of persistent infertility of pigs.
