I stallet hittade vi en dräktig tacka död med ett ordentligt tarmframfall.
Har sökt lite på internet men knappt hittat något, så undrar om ni som fårägare kan dela med er lite om ni har några egna erfarenheter. Hur vanligt är det och kunde vi gjort något för att rädda henne och vi upptäckt det i tid? Behöver vi oroa oss för att det ska hända fler?Mvh Fredrika

Vaginal rupture associated with herniation of abdominal viscera in pregnant ewes.Knottenbelt DC.
Department of Clinical Veterinary Studies,
Abstract
Seventeen cases of vaginal rupture with herniation of abdominal organs were examined. The injury consisted of a dorsal tear in the vagina and, most frequently, evisceration of the bowel. The tear was accompanied by extensive vaginal bleeding.
Serum calcium concentrations were low in the affected cases and the concentrations of beta-hydroxybutyric acid and urea were high.
The average age of the affected ewes was four years (range 3 to 6).
They were generally in poor condition and carrying more than one fetus (2.7 lambs per ewe) although younger ewes and ewes in good condition were also affected.
No primiparous ewes were affected. Ten of the 17 ewes were found dead and six were humanely destroyed; in one, the injury was repaired surgically but the ewe died 48 hours later.

Spontaneous vaginal rupture in pregnant ewes..Mosdøl G.
Norwegian College of Veterinary Medicine, Oslo, Norway.
Abstract
Seventeen cases of spontaneous, partial or total vaginal rupture, in pregnant ewes, involving the dislocation and herniation of the intestines and uterus, were studied.
Four of them also had a uterine torsion, and three of these recovered after treatment. In the remaining 13 cases the condition of the uterus was unknown. The lesion always consisted of a dorsolateral tear in the vagina with a partial or total perforation of the wall close to the uterine cervix.
The affected animals were all in normal body condition. Their average age was just under five years, and most were carrying twins. Most cases occurred approximately one week before expected lambing.
None of the cases was observed to have a vaginal prolapse before the vaginal rupture. Histological examination of one case revealed scar formation in the vaginal wall close to the rupture, which appeared to be due to an earlier inflammatory process or injury. The circulatory disturbance in the reproductive organs caused by the uterine torsion potentially weakens the vaginal wall. This weakness, in combination with excessive tenesmus resulting from increased tension in the uterine ligaments, and in some cases possibly with a lower vaginal resistance due to previous scarring, may be of aetiological significance in spontaneous vaginal rupture.
