I am offered a "super mare" but we have to admit that she is a breeding problem mare. She had a live foal '06 and '08 Then horrible probs delivering in '09.Foal died. Now she settles in '11 and has an embryo at 18 days but is empty at 30 days. Rebreed and the exact same thing. She is fat and healthy and has a caslick. What might we do to help this rare bloodline mare become a viable broodmare. (She is Animal Kingdom's sister)
You're going to have to start with a good breeding soundness workup performed by a veterinarian knowledgeable in the field of equine reproduction - preferably a theriogenologist.
While the pregnancy loss in '11 may be related to the dystocia in '09 there is a possibility that it is not. Remember that the average per-cycle pregnancy rate is around 60% and consequently some mares are - statistically - going to take more than one cycle to establish a pregnancy, so it might just be a perfectly normal statistic. Having said that, there could be issues with the cervix related to damage from the dystocia, and/or endometrial changes and/or other problems related to the dystocia.
So, your starting point is a good breeding soundness workup!
I am not personally acquainted with any of the staff or faculty at Purdue, but note that they do have several theriogenologists, so hopefully it would be a good place to start.
