This is why testing always pays off!
🚨 More than HALF the horses tested did NOT need worming…
…but 1 in 5 were high shedders 👀🪱🐴
After tracking and analysing over 1000 parasite samples across Tasmania, the results honestly shocked even ME 📊🧪
A total of 1057 samples have now been processed, including:
🐴 Horses & ponies
🫏 Donkeys & mules
🐑 Sheep
🐐 Goats
🐄 Cattle
🐓 Chickens
And from 920 horse samples specifically…
💊 557 horses (60.5%) did NOT require treatment at the time of testing using the common >200 epg treatment threshold.
More than HALF the horses tested potentially avoided unnecessary blanket worming 🤯
At the same time though…
⚠️ 187 horses (20.3%) — roughly 1 in 5 horses tested — were HIGH shedders (>500 epg)
⚠️ 34 horses (3.7%) recorded counts over 1000 epg
⚠️ The highest horse count recorded so far was over 2700 epg 😳
One of the clearest trends?
👶 Foals, weanlings and young horses consistently carried the highest parasite burdens.
Meanwhile many senior horses surprised me with consistently LOW counts 👏
And then came one of the most important findings of all…
⚠️ 5 FECRT cases showed the wormer may not have worked properly.
Those horses had BEEN wormed.
Without follow-up testing, they likely would have continued contaminating pasture while everyone assumed the treatment had worked.
The stats showed something honestly pretty confronting…
Some horses likely never needed worming in the first place.
Meanwhile other horses still carried HUGE parasite burdens — and in some cases may have continued shedding eggs onto pasture EVEN AFTER being wormed.
THAT is why evidence-based parasite monitoring matters.
FECs aren’t about worming less.
They’re about worming SMARTER.
