As i have a tendancy to panic easily I am asking others of their experiences of mares who have been scanned in foal however later showing signs of being in season.....?!

I have brought forward this mares next scan to this week after seeing this so it is only a matter of time until i will know for definite but it would be interesting to hear if others would normally worry in this situation before then.

A bit of info on her is that she gave birth to her first foal this year, she is four years, very healthy and our vet apparantly found a very faint heart beat at around 25 days on her last scan. She is now 40 days and she has been showing in season for the last four days.
I have no obvious reasons to believe she may of re-absorbed through stress or infection.

I am also less inclined to panic because earlier this year I did see her showing inseason again when she had around 3 months left remaining and she was very healthily still carring her filly foal when we had her scanned... so it has happened before, but its the fact that we havent passed the 100 days which brings the most concern for this time.

I have asked the advice of vets however of course they only like to comment to a certain extent and I have been told she may or may not still be in foal, and that of course I know it is possible for this to occur because I have experienced it before with this mare but there is obviously no way of knowing for sure before we have her scanned again.

I have also just worked out that this is indeed her natural cycle time for being in season also, which gives me more hope as I have experienced a change in ovulation/ cycling time if a pregnancy has been lost before where their cycle no longer matches to its orginial pattern when inseminated.

I'm sure my concern is unnecessary and I am very excited/ nervous for later this week, but how common is this from others experiences?

Many thanks!

I have never experienced this with my mare but I do know that some mares have shown signs of being in season all the way through their pregnancy.

Around 10% of pregnant mares still show estrus. The only way you will now for sure is to have her checked again. Interestingly, those mares that are pregnant but show estrus have a slightly higher percentage of filly foals (don't go buying a pink halter and then complain when you get a colt next year though!!!).

Thank you both for your experiences.

Great news.... she still in foal!!

So at least I can relax now, the trauma I went through to achieve a pregnancy with this mare through AI, mortified wouldn't have come close but thankfully she looks to be in that small catagory who do still show in season so i now know for future.

Thats a very interesting observation Jos, with regards to a higher percentage filly producer! Has there been any research on that area at all? I'd be very interested to learn more if there has been!
Coincedently I was advised that this mare would more than likely be a filly producer if she was to take after her dam lines, and so far one foal and one filly on the ground!! So, this may be very possible!
Although on the other side others claim it is purely the male who determines the sex, I'll try and find some time to look in to this soon!

Hi Amy, just a thought - both times that my mare has been with foal she has showed signs of full heat. The first foal was a wonderful filly, the second was a colt. Not sure if there is any scientific reasoning that will give you one vs the other.

It was work done by Ginther some years ago. You'll have to go and dig for the exact reference.

It is the sperm that decides the sex of the foal. XX = female; XY = male. The mare provides the X and only the X, so it's up to the stallion to choose the "why"... :-)

Hi Jos - apparently my baby stallion couldn't decide on the "why" LOL. He has a half sister that is 3 months older than him.

It's not even close to an absolute (just a tendency towards a higher percentage of fillies), hence my prior caveat about not whining if you buy a pink halter and get a colt! :-)
