Hi - I recently bought 2 cob yearlings who had lice and red threadlike worms in their droppings. I wormed both with 3.5 grams of ivermectin at 18.7mg/g and praziquantel at 140.3mg/g. Many worms emerged - small red threadlike (strongyles?) and what looked like grey earthworms! I have collected all droppings to reduce pasture infection - how long should I continue to do so?
I realise now having read your pages that I should have dosed for encysted larvae and there was a risk attached
- how soon can I dose them safely with moxidectin/5 day guard for this?
- Both still look pot bellied a week later - how soon will this look disappear or are they still likely worm laden? |

Hi Jo,
Obviously DRO will be the one to answer your question, but I understand what your going thru.
Im in your same situation: new yearling, pot-bellied, bad hair-coat etc..., DRO advised me to do the Debilitated horse method described in DRO's article. My filly is responding well to the treatment. No colic or diarrhea. Its only been 2 weeks and she is already looking better. Of course your situation is a bit different as youve already wormed. But keep an eye on them till you get veterinary advice as so many dead worms can cause blockage colic.
Sincerely,
leslie |

Hello Jo, the red worms are strongyles (could be small but probably large) and the large grey ones are round and/or pin worms. You will find photos and complete descriptions at, Diseases of Horses » Colic, Diarrhea, GI Tract » Parasites and Worms.
Actually Jo, for heavily parasitized horses we suggest you start slower than a dose of moxidectin. You will find a description of a recommended deworming schedule for debilitated or heavily infested horses in the article. Depending on their condition and the amount of damage done to the bowel it could take upwards to 3 months before there is a big turn around during the warm months, longer during the winter. First look for them feeling better over the next few weeks and no further progression of the wormy look.

Thanks to both of you.They seem to have survived my over eager worming on their arrival with no ill effects thank goodness. One has already shed his winter woolies and looks shiny although the other hasn't begun to moult yet. Their stools are normal with no obvious worms or eggs. As they had a full dose of Ivermectin/Pyrantel wormer to begin with I guess I'm now at the wait 4 weeks and worm again with Ivermectin stage of the debilatated horse programme then? Or should I add a 5 day Panacur Guard for encysted worms now?
Also they are still rubbing under their tails so should I do something again for pinworm? Thanks for all the advice! |

I would suggest you follow it up with monthly moxidectin until plumb healthy looking then put them in the regular deworming program.
