Title sums it up. Just checked the mare this morning, it was try number 5 in two breeding seasons and mare was not pregnant. She is a 9 year old maiden. We have done everything with her, culture, cytology, biopsies, oxytocin protocol, regumate, flushing and putting in antibiotics after insemination, and nothing. She has been bred with fresh and frozen semen all by the same stallion. We also gave her SETTLE at the end of the last breeding season, and that made her terribly ill, she had an adverse reaction to it.
I will say after her third negative preg check last year, she had a positive culture and cytology for e-coli. We got her cleaned up and verified it with a lavage culture at the end of last breeding season, and checked her again before we bred her this year and she was clean. Biopsy last year came back I believe as a 2a. The vet is going to do another culture and cytology on her tomorrow, so we will see what that shows. I will also say that the semen we have been working with is not the greatest. It does get mares pregnant, we actually have a foal by that stallion out of another mare, but the vet says it looks average to poor under the microscope.
One side note, the mare has been on regumate since 5 days post ovulation, up until the check today, and the vet said she had edema, which she shouldn't since she has been on regumate. Don't know if that adds another piece to the puzzle or not.
The vet has said maybe it is a compatibility issue, how often is that the case? The only reason I even decided to breed this mare was because I liked this one stallion so much. She said maybe breed her to another stallion with better semen this year, and assuming she gets pregnant then go back to the one I like next year. She also said that if we use a stallion with great semen, then we wouldn’t have to wonder at preg checks if the semen was the issue. I am hesitant to do that, because first we won't really have the extra space for the foal I wasn’t planning for, and two my pocket book is getting low fast. The vet bills alone have been close to $10,000 when you count the incident with SETTLE, and that isn't including collection or shipping fees. Yikes!!! Please any advice is welcomed, I am going crazy.
If compatibility was the case, and she does get pregnant with another stallion this year, would there be any use in trying with the original stallion next year while she has a foal at side? A lot of ifs I know.
Probably no point in trying with the same stallion. Incompatibility is incompatibility...
Note too, that after 3 cycles of breeding in the same season, the uterus is getting pretty tired and insulted, so the chances of establishing any pregnancy is significantly reduced.
