Why do a Faecal Egg Count (FEC)?
Because not all horses shed the same number of worm eggs, and we want to drench the right horse, at the right time, with the right product.
How much poo do we need?
A glove-full is perfect – we don’t need a bucket!
💩Collect fresh poo (ideally within an hour of being passed)
💩Pop it in a sealed bag, squeeze the air out
💩Refrigerate if you can’t get it to us straight away
💩Get it to us within 24 hours for the most accurate result
Even horses with “low” FECs can be intermittent shedders, so we look at the general trend over time rather than a single result. And remember: FECs don’t detect encysted larvae hiding in the gut wall.
Spring drench tip: 🌱🌱
Spring is a great time to give a moxidectin drench – it’s one of the only products that kills encysted larvae. Use it strategically (usually once a year) as part of your worming plan.
Pasture hack: 🐑🐄
If you can, cross-graze with sheep or cattle. They don’t share the same worms and will help “mow up” each other’s larvae, reducing pasture contamination.
Ticks: ✅
We’re seeing ticks get more resistant every year – some are already on property this season. Many of us are using off‑label topical products with good results.
