I know these are a common thing in young horses, but am more thinking aloud here, but welcome any thoughts and advice.
Two fillies, one a May '11 foal, the other April '10, the weaner is mine, the other a friends who arrived in October with a known worming history. Wormed on arrival with Ivermectin, then again with Pramox sooner than needed in early November, but to fit in with all the others worming dates. The weaner was wormed 12th Jan 2012 the day before she went away for weaning. Place she went to has small turnout paddocks which, like ours, are poo picked daily.
On Tuesday while extricating frozen poo from their paddock I found an Ascarid, 5" or so long. The older one was coming up for worming shortly but I gave her an Ivermectin right away. My logic (and I only had one syringe) was that the foal was less likely to have had mature Ascarids having been wormed so recently. More wormers on order now. Is this the most likely thing and, I can't believe whichever one it was only had one worm, but so far by Thursday morning I haven't found any more from either of them.
I egg counted the 6 year old, and as ever <50 epg. I wormed the three year old, and next time I shall do them the other way round, and do Tapes in all of course. Those are the only horses on the place.
I know that they gain immunity as they mature, the only other experience I have of these worms is in two weaners that came to live in a barn for the winter, despite being wormed on arrival one, and we never did know which one, passed Ascarids, and a worm dose produced a lot for a long time.
Thanks in advance...
