does anyone have any ideas of why my mare hasnt come into foalheat yet she aborted twins on 5/2/09 so i would have thought she would have by now. and she still has that pregnant look to her belly could she think shes still pregnant . she still acts pregnant stricking out at my stally and other horses on the yard that come near her.
She should have had her foal heat 7-10 days after foaling. Was she teasing on at any stage? She could have shut down and may not be cycling at all. An idea would be to have her scanned to see if there is activity in her uterus or if she has fluid and to swab her to make sure she is clean. Did you flush her or treat her with antibiotics post aborting?
Foaling or aborting that early in the year, the mare may go into winter anestrus. While the average interval to "foal heat" ovulation is about 10 days, the average range is 5-15 days, so it might be that she did ovulate either early or late, and you missed it, and then went into winter anestrus.
Either a blood-progesterone assay or an ultrasound would be beneficial to tell you if she has active luteal tissue present, as if she does, she is probably cycling, but not showing it.
Treatment with antibiotics post-abortion is contra-indicated in the event there is no identified cause related to a pathogen that would be sensitive to the antibiotic. Indeed, if the abortion were due to a yeast, you could create a terrible mess if you used antibiotics!
Before doing anything else, I'd have her ultrasounded, and discuss her condition with your vet.
Mary Anne, We're having some difficulty getting mares to cycle as well this year. We had a mare abort a hydrops pregnancy on 26th December, She absolutely flooded the place with fluid after aborting. The foal was sent off to a lab for a post mortum just to be sure and everything eas fine, so she aborted just because of the hydrops. We flushed her for 3 days afterwards, treated her with antibiotics and oxytocin to help her expel the rest of the fluid. As it was December we immediately put her under lights at night. She ovulated foal heat at 9 days, we swabbed her and she came up with a moderate staph growth so another 3 days of flushing and antibiotics. On her next heat she had fluid again but swabbed clean . On her next heat she had no fluid and swabbed clean, she was covered, scanned two days later and had ovulated. She now had a milky coloured discharge from her vulva. She'll be scanned, 16 days on Wednesday.
The second mare also was a mare that aborted sometime between the start of November and End of December. She was covered the end of may, scanned at 16, 18, 30 and 45 days in foal. She was scanned again the end of October and all was fine. In December we noticed she was bagged up slighty, we thought she might have placentitis so called the vet and she was examined and found to be empty. We never saw any discharge of found any foetus so we don't know when or why she aborted. We scanned her last monday and she was in season with 20mm folicles, no fluid, we speced and swabbed her, swab was clean, scanned again on Friday and only still 25-28mm folicles, fluid on the scan, still in season. We flushed her for the last 3 days but won't cover her on this heat.
The next mare foaled 32 days ago. Scanned foal heat, had a 40mm folicle, on day 8, no fluid, swabbed clear. Scanned again at 26 days foaled, not in season, scanned amd speced again last Friday 30 days foaled, still only small folicles (15-20mm), not in season so we gave her a PG and will scan again tomorrow.
All these mares are in under lights, don't know why they are funny this year.
Maybe try bringing your mare in under lights at night, it might help as it's so early in the season. I agree with Jos with the fact it's early in the year her foal heat might have been delayed the first thing to do would be to ultrasound her. Even if you missed her foal heat ovulation, the CL should be evident on the scan so you know that she has ovulated.
thank you for your input.vet dosnt wont to scan her yet as she needs sadating to be scaned so he say leave her till later this month to see if see comes into heat tease her every other day if she doesnt come into heat scan her then to see at whot stage her CL/ folicle is at.
