Pinworms

[Bobbly]

One of my boys seems to constantly have Pinworms despite regular worming (after egg count done), regular poo picking and with two horses on over four acres, the land is not overgrazed. Any suggestions please?

 

[I love my Spanish horse]

When mine got pinworm i was told they dont show up on worm counts and the only thing that would touch them is strongid-p, worming with anything else is a waste of money and only increases resistance to other things. There is something you can put round the rectum that can help, as thats how they come out and lay there eggs, cant remember the name of it now but vaseline can also be useful. Also got told to disnfect anything he could have scratched his bum on or pood near basically, so stable walls, feed buckets, tail banages etc all need thoughly disinfecting.
None of these things may do anything as they are notorious buggers to get rid of, My boy poos out loads after the strongid but still dont know if he's completely clear yet. The only good thing is apart from being a nuisance and hard to treat, at least they dont do as much damage to the insides as other worm types.

Our old mare had pinworms, the vet said there is a lot of resistance to wormers and that they are finding it hard to clear some cases of pinworms. We were advised to use a pyrantel based wormer such as strongid-p and it did the trick!

Panacur 5 day guard or old fashioned white wormers every 6 weeks should break the cycle

Friend recently bought a horse that had pinworm. Vet intructions were to give 2 1/2 dose of Strongid P, then 1 1/4 dose at 10 days & 20 days. Clean around his bum & wallop on lots of vaseline daily. Seems to have done the job & he is going to be re-tested in August.

My friend's old mare had them and was told by the vet to worm with 5 day panancur every 4 weeks 3 times.

I don't think they can get pin worm from grass ( I might be wrong!!! ) but my vet said it came from mums milk. We had to use a really strong wormer on my mare because they are hard to get out

The eggs are laid around the anus, then rubbed off onto fencing, stables etc. Horses are then infected when they mouth that area of fence or whatever else. This is one of the reasons why youngsters are more susceptible as they are often mouthier. It is also one reason why control is difficult because even if all the worms in the horse are killed, it is also necessary to kill all the eggs deposited on fences etc. Not an easy task and if not achieved then the horse will become re-infected.

The worm passed through milk is Strongyloides westeri. (Pinworms are Oxyuris equi).

Thanks alsiola! I didn't have a very long chat with vet about it she just said they get it from mums milk. I just use to think my mare was an itchy mare but the day after my vet did a check on her ovaries I saw one come out! So I think it came down when her arm was up there haha!
