I have a 1992 warmblood mare (in Germany) who has had 4 foals in 4 breeding seasons. She was bred 3 times by her previous owner when she was not showing her, and I bred her last year & we ended up with a healthy but big colt. Last year she had an infection that was treated prior to her breeding. Her 2004 colt was born in late January. We first used frozen semen (macro straws) in February, to no avail. We skipped March since there were multiple follicles, and then used good quality fresh semen in April, May & June, but she did not take. Although she had a good heat in June. She came back in heat this past week. She has no infections (culture results came back negative), She is full of milk & her big colt has not been weaned yet. Weaning him now (at 5 months) will cause some problems at the farm where she is. She does not show much interest when teased (always been that way). She has a 4.6 cm follicle last week, but it seems to be loosing its size. We thought about using hormones to extent her heat. Any suggestions to get her in foal would be much appreciated as the season is nearing its end.

We have a 12yo Hanoverian mare that had three foals without a problem except that she required Regumate to sustain preg due to hormone levels prior to my purchasing her she was open for a year. We bred her in 2001 and after several tries she finally concieved, unfortunately twins went undetected and she aborted at 7 mos. She retained the placenta and was treated with lavage and anitbiotics. We rebred that year and she concieved only to reabsorb prior to day 25. We have been unable to settle this mare since. She has a clean culture and cystology showing nothing abnormal. Her biopsy is a 2A. We have used oxitocin post insemination even though she shows no fluid pooling. She goes on Regumate on day 4 post breeding. We have tried switching stallions. She was Lyme postitive but has been treated with doxicycline and shows no clinical signs. We are at a loss why this mare doesn't concieve....any suggestions?
