I have a miniature mare who suffered a dystocia year before last. She ended up with a small tear to the bottom of her cervix. My vet said she may or may not be able to carry a foal again and breed her and see.
Bred her last year, she got in foal on the first cycle. Carried the foal to 268 days and aborted. No sign prior that there was any problem. She layed down and the foal came out completely intact with the placenta. It's almost like it just fell out and I'm wondering if the weight and size of the foal caused this with a cervix that might not have stayed closed.
Is there anything that could prevent it from happeing again? Would Regumate be of any benefit?
If you have a premature placental separation, that is suggestive of issues connected to the endometrium and placental attachment. Two possible causes for this are endometrial changes or placentitis.
The former (endometrial changes) may include endometrial fibrosis and can be identified by use of an endometrial biopsy. The latter (placentitis) could be associated with cervical incompetence, and may be identified by videoendoscopic evaluation of the cervix (or manual if there is significant damage).
You would be well advised to have both of these diagnostics performed.
What did the necropsy on the aborted fetus and membranes show?
It's impossible to say if anything can prevent it from happening again if you don't know what caused it in the first place! If there was no necropsy performed, the having the above diagnostics performed will assist with provision of an answer, but it will not be definitive.
Regumate will only be likely to assist if there is damage to the cervix that it can cause to be more completely closed - again, without evaluation you will not know.
