If anyone has any thoughts or experiences I'd really like to hear them right now. I'm feeling very low!

I have a 17yr old NF who I've had 10 yrs. He's grey, and does have quite bad melanomas. He's a bit "special" for a NF pony as he's certinaly never been a good doer, and has always had to go on quite a bit of grass and fed haylage etc to maintain weight. (he eats till he's full and then snores!) But I've always managed to see him just right.

But this winter I just noticed that he'd dropped off. He'd had no change in food. So initially I just put it down to age. Increased his feed a bit, he didn't put any on, but didn't drop off any more. Then in March at a PC ralley (a 12 yr old girl loans him 2 days a week) I noticed he really wasn't firing on all cylinders. He was still jumping everything, but just wasn't flying around with the girl hardly being able to stop as usual! He had been fine the month before.

So we decreased his work, and upped his feed a bit more. I would have had him blood tested but he's very needle phobic and the vet was happy with the way I dealt with it. It was then that I noticed that his poos were getting a bit soft. But I just put it down to the amount of feed.

Then throughout April it got worse. But he actually improved within himself and was back to normal, although hadn't put weight on. So I decided to wait for the spring grass and see what happened. He's 14hh and weigh taped 450kgs He's usually 470kg ish. But the difference in weight was quite visible.

By the end of April the poos were very wet, not piling at all if that makes sense. He was then wormed and it turned into full on projectile water. Yet he was still 100% in himself, eating and drinking normally. Hadn't put weight on, but hadn't lost more. But the vet was called.

Since then, we've worked out a way to inject my very needle phobic pony! We've had to! He's had about 5 blood tests. None have really shown up anything. To those of you who understand these things his PCV Albimum level has been high for a pony of his type consistantly. His latest (Tues) came back with a marked inflammatory response suggesting some kind of inflammatory changes in the gut.

He has a worm count of 0.

At the beginning we tried several different meds to stop it. Codeine eventually worked and the poo went normal. He was then weaned off that onto Steroids. He's on 14 a day. His poo has gone soft again. It's in piles, but not breaking when it hits the ground. He's no different on or off grass. He has been weaned off the steroids to see what would happen, and it got worse, so gone back on them. He's also on Bio Premium (probitoic from vet)

He had a rectal biopsy on Tuesday and I am waiting on the results.

He has put weight back on the last few weeks and looks a lot better. He's still 100% in himself.

Sorry this has turned so long! Probably very boring to read! But if anyone has had a horse with terrible D I'd be really grateful to hear what caused it, and if anyone had one and never really found out I'd liek to hear what you did?

Thanks so much!
 
At the moment he's just having grass and hard feed. I tried having him in 24/7 for nearly a week on just hay and water and it made no difference.

He's been blood tested for everything!
 
Mine did when I bought him and it got much worse when I wormed him. I tried feeding dry bran, I tried pro-biotics, tried pink powder..... the best thing I have found to get him back to "normal" although his poo is still loose is a low protein, no oil diet free from alfalfa.
 

Sounds familiar. Given the time of year he might have had encysted redworms. they do not show up on a worm count as they are buried in the gut wall as larvae, but in the spring can erupt from the gut lining, causing diahorrea, colic and worse.

After my lad had his wormer the symptoms actually worsened, diahorrea, severe weight loss etc i've been told this is because as redworms are killed off in the gut, even more see it as an all clear to emerge. This emergence in large numbers can cause severe inflamation of the gut lining.

Regular worming and poo picking etc doesnt stop encysted redworms (unless the wormer is specifically for that)

Also, tapeworms cause similar symptoms, and these do not show up in egg counts either. They need a blood test which shows anti-bodies.

I hope it all goes well x
 
Yup, vet immediately thought it was redworms too. Hence he was worm tested and wormer with a panacur guard to be 100% sure. However nothing came of it. So the vet is certain it isn't that. (I actually wanted it to be, would have been an easy thing to "fix"). He was also tested for tapeworm, and the wormer the "set it off" was an Equimax for tapeworm.... All the worming test and treatments were done in April, and we still have symptoms.

Feed wise, as soon as it happened he was changed off all high oil etc feeds. In fact he was taken off all hard feed completely for a week and just had hay and water (ruled out grass, hard feed causing it) and was no better.

Interesting to hear all this though! Thanks!

Had biopsy results back and it says inflammation of the gut. No sign of the melanomas. However as my vet says, it doesn't mean they're defo not causing it as obviously it only tests a small area.....

However the last 3 days his poo has actually been breaking as it hits the ground!!!

(sad to be excited about!), so we're reducing the steroids one tablet at a time like a week a time and see if we can find a controlling dose.
 
We had an old pony who went through this too - liquid poo and a drop in condition. The vet tried several things but finally resorted to an old remedy.

Very gross if you are squemish!
The vet tube drenched the pony with a fresh dropping from a healthy horse. Within days the runny poos stopped and he put on weight and never looked back - lived well into his 30's.
