My mare is 120 days preg and tonight I noticed a slight mustard colored discharge. At first I thought it might be diarreah but upon closer examination it appears to be coming from her vulva, I also noticed it is somewhat the consistancy of a yeast infection or foal diarreah yet is mustard colored and noticed there was a good amount around her uretha. She has no temp, and is acting normal, eating normal. The vet had me give her Regumate tonight until he can come out tomorrow afternoon to check her. Could she have a yeast infect or be pooling urine or do you think she could be aborting? At 120 days would you put her on SMZ's or antibiotics until maybe do a culture on the discharge?
Your vet will be better able to tell you what it is, as they will of course be visualising the problem. Something that may be the cause though is that around this time of pregnancy (+/-90 days) the estrogen levels (specifically estrone sulfate) secreted by the fetus rise. This in turn will mean that the mare's estrogen levels will also be increased - it's not uncommon for some mares to display estrus (heat) at this stage of pregnancy. As a result of the estrogen levels being higher, you may notice her urine being thicker and more yellowy - just like it is when she is in estrus - and consequently the "discharge" you may be seeing could simply be dried estrogeny (is that a word? ) urine.
I would not treat with anything unless your veterinarian recommends it. Treatment with SMZ's in the event that it were a yeast problem could make it worse for example.
I put up my question down below for a very similar event. My mare is right in this time frame Jos so this would make sense. At first it was clear thicksih fluid but only when I turned her out in the arena after being in all day(drying her up). Then one day it was mustardy colored. Now it's gone completely. My mare was also kind of acting in heat so I thought she lost pregnancy. Thanks for this explanation. My regular vet is away and don't like anyone else doing my mares. He's going to check her anyway when he gets back. Thanks Terri

Vet came out took a sample of discharge to look at under microscope, reported back no white blood cells and nothing really abnormnal showed. He us the mare and foal was very active. Upon palpation he said uterine tone was good, cervix tight. No temp and still acting normal except for the discharge which seems to expell more at end of urination (looks like diarreah). He did find a spot of irritation just inside the vulva and thought possibly a bee sting?? Feels it is a vaginitis wants to see if it clears itself over next couple of days. I am nervous though doing nothing as I do not want to endanger the pregancy if it can be avoided. Jos, any suggestions?
As your vet has been out and evaluated the mare, your best bet now is to follow your vets advice and not some from someone over the Internet that hasn't seen the mare (me!!)!!
Hang in there, and if you have more questions, get hold of your vet and ask them - he's your most valuable resource right now!
