Milk from udders but not pregnant?!

Thunder is 16. She has not been around a stallion in the last 10+ years. She is in a paddok with 5 geldings, and One likes to mount her. I have heard of cases where the gelding is not gelded all the way. She has never been pregnant.
There was a lot of milk coming from the udders, I could get a few oz. Easy. Her udders are very large and she liked it when I rubbed them. It is not mastitis or any other disese that we know of.
I have worked with horses for a while, and have been around many pregnant mares. The owners are away on Vacation. She is not very big around the stomach but I was had a mare who had a foal and was not very big round either.
This mare has been acting odd the last few months. Very distant from other horses and very moody.

If you have any idea at all it will be greatly appreciated!!!

Thank you!

Wow! That IS odd! But it sounds to me like to have a pregnant mare on your hands.....you might want to call the vet and have her checked!

Hm, she could be pregnant...I'd let a vet check her out just to be sure. ;) Be prepared for the unexpected! There could be a chance she is from that gelding mouting her, I've also heard stories like that before.

Very strange. I'd suggest getting a palpation or ultrasound done on her...

I would really like to hear the results!!

Wow that's weird. My gelding mounted this one mare at horse camp, of course, in front of everyone. Everyones all oh pretty stud but he not one. This will be interesting. Keep us updated!!

I don't think she's preggers.

I had a palomino mare once upon a time who was never even exposed to anything that dangled.

She produced a milky-like substance...asked the vet and it's basically normal; no nutritional value (for saving and giving to a needy colt)

The more I "milked" her, the more she produced. So I just quit milking her...she eventually dried up :)

Can horses have phantom pregnancy’s like dogs can?

When that gelding mounts her, is that all he does? Or does he do the entire full service?

That is very interesting. If you can I would get a vet out and check things. Because of what you are describing and the time of the year it is, it seems to me that you might have a pregnant mare. If she isnt pregnant you should be able to figure out what she is producing.

The whole pictures just doesnt make sense.

A lot of geldings mount mares but they jump up and that's all they do, if this "gelding" mounts and does a full serving that shows me this horse isn't gelded.

Yipes. My mare is doing something similar. I bought her in late September and I have no idea what kind of horses she was with at that time. She isn't very big in the belly, but more so than usual. She is producing a yellowish looking liquid from her slowly enlarging teats. But, only if squeezed. (I reached under to feel if they were hot and maybe infected or something and I accidentally squirted some out).

She hasn't been bred in at least 5 years. I don't know about before that. A pregnancy exam is really the only way to tell. Apparently there are other reasons they could produce milk. My vet said it could be a cyst on an ovary that creates hormone imbalances. It could also be a phantom pregnancy, but two separate vets seemed to have the opinion that this is pretty rare.

A gelding can be a "rig", meaning he has a hidden testicle that wasn't removed during gelding.. or he was simply done improperly and things were missed. That's also rare too though I believe.

I'm waiting for a WeeFoal pregnancy test to arrive. Its less expensive than a vet exam, and you always run at least a slight risk every time the vet palpates. Of course an ultrasound is best.

Have you found out if she is pregnant???
