Pinworms.

[Chestnut mare]

I've been on my current yard 18 months and I'm having an on going battle with pinworms since I've been there.
My horse has never had worms before now I see the pinworms in her droppings and around her dock.
She has been wormed regularly I use the equest/equest pramox 1 year then eraquel/equimax year 2. These wormers all treat pinworms.
She is in with 1 otter mare who is clear and wormed with the same product at the same time as my mare.
The vets advise was to use a panacur guard 5 day course, which I did but still has not cleared the problem .
I know the worms are harmless just irritating and itchy for the horses.
Any suggestions please?

We had this trouble last year with the old pony, wormer resistant pinworm. We got rid of it by repeating the Panacur 5 day treatment but not before he destroyed his haybar by rubbing on it!

Good luck.

By the way, have you 'painted' her dock area with Panacur? That might be worth doing.

There is a known pinworm resistance and when I spoke to the man on the wormer stand about it, he suggested a course of wormers, (he gave me the names but I can't remeber them, they're written down at hoome) disinfecting everything and anything they can rub on (i.e posts, fences, rugs etc.) and if it gets really bad then to get the vet out as they can give special pin worm wormers

We had problems with pin worms last year. The vet took advice from an expert researcher who suggested panacur liquid - 2 courses 28 days apart - and they provided us with a liquid to paint their bottoms daily for 30 days. No joke on a livery yard of 40+ horses!!

The research vet's view was that modern wormers have been created to be easily absorbed and do not reach the lower intestine in anything like the concentration to be effective against pinworm.

As you say they are not life threatening but a significant nuisance!

I agree with Diane above. Painting on wormer mixed with propylene glycol, plus cleaning all surfaces as well as you can, is the way to go. As this is an off licence use of wormer you must involve the vet.

As said above modern wormers do not easily reach the hind gut where pinworm live. Our information suggests strongid p as a better option than modern wormers.

We get asked so often about pinworm, they are a common and irritating problem, so much so that I have an information leaflet to email out about pinworm. Thankfully they are not a damaging horse worm and the only harm done is where the horse gets very irritated and rubs a lot.

My big lad arrived at the end of last summer and was wormed on arrival with Panacur guard as his worming history was very hit and miss but he started rubbing himself raw not long after arriving, vet found pinworm eggs after taking tape samples from around his anus.
Treated - on vet's advice - with a triple dose of ivermectin followed by 5 day course of panacur 7 days later and ivermectin painted around his anus (I think that was for either 21 or 28 days). Fingers crossed it seems to have done the trick.
The triple dose of ivermectin made him scour for weeks and ended up using codeine to sort him out but it did clear the pinworms. Not sure how much the fenbendazole did as the initial course didn't have any effect on the pinworms, so possible/probable resistance there but vet wanted to repeat it in conjunction with the ivermectin x3 and the solution to paint on.

Chestnutmare your rotation of wormers is between brands not between distinct chemical groups and you are building resistant worms

Popstrop Horrified at your vets solution!

 

[Chestnut mare]

Thank you . Will have a look into the suggestions made.

Treat as above but I would also consider changing their field during the treatment - they may have rubbed some eggs off in their current one.

Hi, I have an ongoing problem with just one of mine despite them all being in the same field together! I found out that equest and equest pramox doesnt actually cover pinworms and I had been using it regularly. I switched to equvalan & strongid P they both say on the box they cover pin worm. Both work!

One of the cob mares had a terrible time last summer and rubbed herself silly and raw under her tail. The vet said it was pin worm owner kept anus clean and we all wormed and touch wood nothing so far. There is a piece on different types of worms in one of the horse mags including pinworms.
