What a beautiful time of year — all those cheerful foals in the pasture! That makes everyone happy, right?
But how should you approach your deworming strategy? Foals are vulnerable — so should you deworm routinely or not? We answer frequently asked questions.
Should I deworm my pregnant mare?
This is certainly not always necessary. If your mare is healthy, you can submit a manure sample 3 weeks before the expected foaling date. If the result is negative, you don’t need to do anything. If it’s positive, you still have time to treat before the foal arrives.
Should I deworm my foal preventively?
We recommend submitting a manure sample from both mare and foal between 10 and 14 days after birth.
By testing manure regularly, you get a clear picture of the gastrointestinal worms present. This insight helps ensure that any infection can be treated specifically and unnecessary deworming is avoided. This reduces resistance and protects the gut flora of both mare and foal.
Foals are vulnerable, so it is important to submit a manure sample every 2 months during the first 8 months. See the schedule below.
If you haven’t tested since July, now is the time for an autumn worm check. Based on those results, deworming may be necessary now — followed by treatment for encysted small strongyles once the weather is cold enough in winter. Of course, this is always tailored advice. All our customers receive an appropriate end-of-year recommendation by email in November.

Based on the results, the parasitologist will evaluate after 6 months whether preventive deworming is still necessary.
How can I recognize a worm infestation in my foal?
Does your foal show symptoms like lethargy, fever, a rough coat, coughing, nasal discharge, weight loss with a bloated belly, diarrhea, or even colic? Always contact your vet if you’re unsure about the health of your mare or foal.
What can I do to prevent a worm infestation?
Good stable hygiene is essential to prevent serious infections. The most important measure is to remove manure daily or at least twice a week from the pasture, paddock, and stable. It is also important to keep the stable clean and dry. For more information about prevention, visit our website!
