Panacur is Fenbendazole- so any horse that was "allergic" (and this has never been heard of so I would strongly advise you to inform the manufacturer) would also be allergic to Fenbendazole. Worm counts do NOT pick up on encysted small strongyles and they are the ones that will kill your horse with almost no warning at all, and worm counts do not pick up on Tapeworms, although there is, now, a separate test for Tapeworms. Whatever else you do you do HAVE to worm for Tapes and encysteds at least once, ideally twice a year. If your horse appears to have a reaction to the five day course of Fenbendazole it is most probably because it has a heavy worm infestation and I would advise you to get it checked. Vets are not always the best people to ask about worming horses, they are often a bit vague and rely on leaflets sent to them. I would rather work it all out form the Internet in this particular case, as the information is all out there to glean.
Anything longer than eight week cycles is pointless as it will help build a resistance to the chemical by under worming. Strongid , especially the every day one, I do not like and will not use. There is already quite a high resistance in some areas, which means you are under worming every other time, which cannot be a good thing. I use only Ivermectin, every weight weeks. In spring and autumn I also use (as well as, never instead of) the five day panacur and Praziquantel. That seems to get almost everything. I never, ever rely on "not seeing worms" I would also not rely on a microscope unless you have training in what to look for. Encysteds show on NO test.
Worming needs to be done regularly and accurately and I am not changing to worm counts any time soon! Once a year, one count per field. If anything in a field needs doing, they ALL need doing. I do not harrow a field that is being grazed, I harrow the hay field and leave it. The fields I am grazing are harrowed, weed killed and then swept up and burned. That way the horses go back onto clean pasture to foal. My mares are wormed up to foaling, so they do not need extra worming after foaling- the wormer will not be passed through the milk to the foal, but it will be passed in the blood through the placenta. I worm foals at ten days with Fenbendazole- this is roughly when they start to graze seriously and when I start offering them feed.
