A friends new horse came with pin worm we double dosed strongid p on the 18th april kept in 24 hours, turned out on new fresh summer field sorted! Now my grass in what was winter field is ready to make hay, will this be ok to feed or will it re introduce pin worm? Will the eggs have died off yet? Should i sell my hay and byenew in? I really dont want to have to do that? What should i do?
 
I may be wrong, but I thought that fields had to be rested for at least 6-8 months for the worms to be gone. I also read somewhere that hay can be alarge source of worms which is why iit's so hard to control with egg counts, they. Can suddenly get a huge burden from "nowhere". Personally I'd continue to make the hay but probably sell it on. Lol, that sounds really harsh but if you know it's been in contact with the worms, they won't have died in 3 months. Hope this is some form of use! Lol, just mo :-P
 
Is it not abit irresponsible to sell hay you wouldn't feed yourself to other unknowing owners? I'd personally be VERY annoyed if I found out my hay supplier was giving me stuff he wouldn't give his own horses, especially if it could introduce worms.

I know you'll likely be at a considerable loss if you don't sell and still have to buy in new...but I personally wouldn't be comfortable introducing worms to other people's herds knowingly.
 
It will be fine, eggs are only a problem if present and at the infective stage of their lifecycle and although in theory they could still be present in hay it is unlikely that they will reach L3 as they don't generally do so well with dessication.
 
Seeing as foxes often carry pinworms, I think this is unnecessary worrying

Plus they don't actually do any damage, they are very gross and cause itching

The only thing that really shifts them in panacur guard 5 day

some horses do considerable damage to themselves when they have pinworm, it is due to the itching and there is considerable resistance to all current wormers on the market.
 
Yes but it is only scratching as opposed to irreversible damage to the gut.

The reason why modern wormers don't work is that they are too easily absorbed and never reach the hind gut where the adults are. Its not resistance per se, merely the mode of deployment.

Some people have had success with using ivermectin externally to catch them.
 
I think its totally disgusting that you'd consider selling what you considered to be bad hay to someone else! Perhaps you better hope that the person you buy new hay from hasn't done the same to you.

on one of the yards i go to 7 horses have had pinworm (it has been reported and they are in their of fields-always have been)- 2 of them have areas all around their back ends that are so scarred that hair will not ever grow again,one of them has done the same to his dock so has about 30 tail hairs now.

i agree re deployment methods vs resistance.

but dont under estimate the damage that can be done
