Pregnant mares coming back into heat

[dianchi]

Hi Guys,

Looking for some help and advice.

Im breeding for the first time from my TB mare, she has foalled before (in ireland) and nothing is know of that foal.

She took on the first attempt at AI and scanned in foal at 16 days, vet was a little worried due to size and came back again and scanned at 20 days. She was particularly stressed that day and the scan wasnt brill and the scan looked about the same size. She checked her overies and said that there were folicals coming up.

Two days later she has some slight clear fluid and has been tarting about a bit to her best friend (mare) so now im worried that she has re-absorbed. Vet is back tomo to scan again but i just wondered if anyone else had this happen to thm before?

Thanks in advance.

It could be that she has lost the pregnancy (mares don't actually re-absorb, it's myth)

I would have the vet rescan her although if the vesicle hadn't grown on the previous scan I wouldn't hold out much hope.

Good Luck x

Mares can have follicles while pregnant, so that is not a concern. However, the fact that your vet was concerned about the size and she is appearing in season does seem to suggest she may have lost the pregnancy. You should definately have a definitive answer tomorrow.

Another point - healthy pregnancies grow at a very standard rate - it should have increased in size very obviously between 14 and 20 days. Has she been mapped for cysts prior to AI? The fact the 'pregnancy' is still showing at the same size suggests maybe it wasn't even a pregnancy in the first place. Cysts can often look like small pregnancies - this is why we always map cysts on every mare we have in, to avoid this kind of confusion!

Hi - My mare was successfully AI'd last year and appeared to come back into season afterwards - she is a well known tart and was flirting outrageously with my other horse - it had no effect whatsoever on her pregnancy. If you are concerned though, I would have her re-scanned to be on the safe side, be silly to waste a year.

My mare was inseminated at the end of April this year, she was scanned 15 days later and vet wasnt sure whether he could see a pregnancy or whether she was coming back in to season. He came out 4 days later to rescan (by this time she was highly in season) and obviously scan showed that she was not pregnant.

She has now been done again, due to be scanned friday, but is showing signs of coming back in to season - not meant to be for her this year.
