Gelding has discharge from anus????? Help!

My rescue OTTB has a white discharge sort of like bird droppings that are always dried around his anus (sorry fo crude terms, I'm trying to be as diplomatic as possible)

I immediately assumed worms as I had seen one, very large and live adult in a pile he left for me when I first got him, and have wormed him twice with Ivamec in the last 3 or 4 weeks but it's still there?

He doesn't seem collicky, he's eating fine, in fact he's gaining weight. The only thing he does that would concern me in that general area, is that he moans loudly when he goes, which I have never really heard a horse do....

Has anyone experienced this? I do have pictures, but I wanted to see if anyone had and idea first before I display his cute little hiney on the world wide web ;)

Call a vet. NOW.

I have no clue what it is, but if he's moaning when he defecates, there's something wrong.

I would call your vet....it sounds like he has worms and might have a resistance problem or and over load of them which if that is the case you need to be careful......as you could end up with impaction colic.

I don't think is it unusual for a horse to moan.......my geldings do it all the time and I know for a fact they have no worm issues.

Generally when dealing with a horse with an unknown history a power pac is usually used.......5 days of a double dose of Panacur.....BUT I would check with your vet first.

While I don't mean to downplay the situation, my mare always gives a grunt/moan when she poops. There is certainly nothing wrong with her.

If he is straining, that is a problem. Are you sure it's not just flakey, dandery skin?

I would call your vet and describe what's happening, maybe email him the photo to see if s/he says they need to come out.

Sounds like pin worms. I wouldn't worry about the groaning, I've heard plenty horses do that when they poop. If he's straining to poop then yeah, you may have a problem. If the stuff around the rectum is like a yellowish powdery kinda looking stuff it's pinworms.
I'd switch to a different class of wormer. Simply switching brands isn't effective.

Do you always see worms if they are there? I haven't seen any since the last one. But if it can be that serious, I will definitely have my vet out ASAP! As for the moaning, my mare does it too, but not as long or as loud as he does.... Texas was a 2 on the Henneke scale when we first got him, and has now bumped up to a 3 in the 7 weeks I have had him so far. The girl who gave him to me originally rescued him and she SAID she had a vet out and that there was nothing wrong with him, and she would give me the receipt. Well, she never did. Now, I'm curious if there isn't more to the story.

I would collect a manure sample and have your vet do a fecal egg count, and set up a de-worming schedule.

It's funny I was just reading the thread on that :)
I think I will. Anyone know how much that runs cost wise?

sorry to double post, but I just read what you said....what do you mean by class?

Here, a fecal is like $15.

By class, I assume the poster means pyrantel pamoate, praziquantol, fenbendazole, ivermectin, moxidectin, etc. They cover different types of worms.
