Why does a sheep have a prolapse?

2 months 4 weeks ago #559373 by spoook
Perindale (perindale cross) ewe, was in lamb August last year, had a prolapse, prolapse dealt with with new fangled harness contraption, lambs both died (overcooked).   
Anti B jab and full recovery, no problems since......
Until a couple of weeks ago.
Prolapse again.  Why?
Not in lamb, not overly fat, healthy in appearance.   Got us stumped.

There are no bad questions only those that are not asked.

We have had enough experience with bearings to be considered experts :-) , but only with putting the harness on :-( . As to "Why?" is only ideas to us.
1st Is this a vaginal prolapse like the one you fixed, or is it an anal prolapse this time? But very likely vaginal.
2nd Bearings cause the body to go into shock, which causes a break in the wool. So don't tie the strings of the retainer to the wool. We make a fairly tight waist band of twine then tie the retainer strings to that. We then put on a looser neck string and tie the backbone string to it so that she is able to reach the ground, but not much looser.
3rd If the prolapse has been caused by an infection she will need lots of antibiotics. If the prolapse has got dirty she will need lots of antibiotics.
4th Putting a bearing in is much easier if the sheep is on it's cheat and a person is holding it's bum in the air,
5th We found that Campylobacter vaccination reduced the number of bearings hugely. We once had the opportunity to blood test recent vaginal prolapse ewes for recent Campylobacter infection, and all 4 of them did.
6th One of the indications of Campy infection is late lambing ewes, where they have got pregnant early, have got infected and aborted, and have recovered to get pregnant again.
7th The have been suggestions that too short docking makes it worse.
8th Campylobacter causes abortions sometimes, so annual vaxing is needed. Campylobacter is everywhere.
9th Other infections probably cause uterine infection, which may lead to bearings.
10th Basically, the pelvic floor muscles are not strong enough.
11th There are probably many different causes of bearing, and we don't know all of them yet :-( .

We used to not re-mate bearing ewes, but now we would not cull for that alone. But we most definitely cull for non-pregnant bearings, especially in a ewe that had a bearing during pregnancy. If she were mine she would be on my dog meat list if she heals up :-( .
