Faecal Worm Egg Counts (FWEC)
Perth Equine Vets / Faecal Worm Egg Counts (FWEC)
Worming-based on FWEC results are vital to prevent resistance from becoming a real problem in our horse population. Blanket worming all horse regularly is no longer recommended and should be based on FWEC results, and risk factors that make them more predisposed to have a higher worm burden.
Risk factors for high worm burden:
Your FWECs should be collected and labelled individually and dropped off for a 48-hour turnaround on results. All FWEC will be interpreted by a vet, and worming advice given accordingly.
Samples should be collected, in general:
If your horse requires worming outside of the annual worming window (November/December time) based on FWEC results – it is recommended that a follow-up FWEC is completed 14 days after the treatment to ensure it has been successful. This is free of charge, as long as the wormer is purchased from the practice.
How to collect an FWEC for your horse:
Pick a fresh dropping (less than 24 hours old), take several pinches from different faecal balls of the same dropping to get a representative sample.
