Prolapse of the Vagina and Cervix
Prolapse of the vagina and cervix commonly occurs in the last third of pregnancy including the immediate pre-farrowing period.
- In the early stages the protruding tissues appear between the lips of the vulva and return to their normal position when the sow stands.
- With advancing pregnancy the prolapse may remain to the exterior and as soon as this occurs the animal should be removed from it's existing environment and loose-housed.
- The tissues become swollen with time.
Causes / Contributing factors
- It occurs usually in older fatter sows that are heavy in pig.
- It is a response to increased abdominal pressure together with a relaxation of the internal structures that support the neck of the womb.
- It is more common in older sows.
- Sows housed on tethers with slippery floors are more prone.
- Stalls or tethers with floors that slopes too steeply to the rear predispose.
- High levels of starchy feed intake, produce excess fermentation and gas and an increase in abdominal pressure.
