This study revealed a 7.8% overall occurrence of reproductive organ/tract abnormalities which consisted of ovarian hypoplasia, cystic ovaries, endometritis, pyometra, hydrometra, haematosalpinx, salpingitis, cervical atresia, vaginitis, and vulvovaginitis in does slaughtered at Nyagatare abattoir in the Eastern Province of Rwanda.
The overall prevalence of salpingitis and haematosalpinx in this study (13%) is higher than that from other studies ; variation in prevalence from other studies could be attributed to different animal production systems and nutritional conditions that vary from one location to another.
Although the exact cause for tubal torsion is not known, many etiologies have been proposed, these includes anatomical abnormalities (long mesosalpinx, tubal abnormalities, haematosalpinx
, hydrosalpinx, hydatids of Morgagni), Physiological abnormalities (abnormal peristalsis, hypermotility of tube, tubal spasm and intestinal peristalsis), Haemodynamic abnormalities (venous congestion in the mesosalpinx), Sellheim theory (sudden body position change.), Trauma, previous surgery or disease (tubal ligation or pelvic inflammatory disease.), Gravid uterus.
