Fecal Egg Count Testing Program

For an evidence-based, individualized approach -- fecal egg count testing lets your vet target deworming to your horse's actual parasite load rather than a fixed calendar schedule.

Why this fits you

  • You want deworming decisions based on your horse's actual parasite load, not a fixed calendar.
  • Reducing unnecessary dewormer use (and the resistance risk that comes with overuse) matters to you.
  • You're working with your vet who can run and interpret fecal egg counts.

Fecal egg count testing measures your horse's actual parasite egg shedding, letting your veterinarian determine a targeted deworming approach based on real data rather than a fixed calendar schedule -- this is the current, evidence-based standard many vets recommend, partly because it helps reduce unnecessary dewormer use and the parasite resistance that overuse contributes to. This is genuinely a conversation for your vet, not a decision to make from general information alone.

When this isn’t the right fit

A testing program is not a do-it-yourself plan, because it needs a veterinarian to run and interpret the counts. If you cannot reach one who offers fecal testing, ask for a schedule they recommend, and never skip a treatment on the strength of one result without your veterinarian's advice.

Frequently asked questions

Why is fecal testing considered better than a fixed schedule now?

Fixed calendar deworming regardless of actual parasite load has contributed to parasite resistance to dewormers over time -- testing-based approaches target treatment to horses and times when it's actually needed, which many vets now consider the more responsible standard.

How often do I need fecal testing done?

This should be determined with your vet based on your horse's individual shedding classification and situation -- it's not a fixed universal schedule, which is part of why vet partnership matters here.

Can I do fecal testing myself instead of through my vet?

While some testing kits exist, interpreting results and determining appropriate treatment based on them is genuinely vet territory -- work with your veterinarian for an approach tailored to your horse's actual situation.
