Horses should be dewormed for strongyles based on a strategic plan rather than a fixed schedule. Typically, deworming occurs every 6-12 months, but frequency depends on factors like age, pasture management, and fecal egg count results. Regular monitoring and veterinary advice ensure effective parasite control.
How Often Should Horses Be Dewormed for Strongyles?
Understanding the right frequency for deworming horses is crucial for maintaining their health and preventing resistance to dewormers. Strongyles, one of the most common equine parasites, require specific attention. This guide will help you determine the best deworming schedule for your horse.
What Are Strongyles and Why Are They a Concern?
Strongyles are parasitic worms that can cause significant health issues in horses. They are divided into large and small strongyles, with small strongyles being more prevalent. These parasites can lead to:
- Colic
- Weight loss
- Diarrhea
- Poor coat condition
Effective management of strongyles is vital to prevent these health problems and ensure your horse’s well-being.
Factors Influencing Deworming Frequency
The optimal deworming schedule for horses varies based on several factors:
- Age: Young horses (less than three years old) are more susceptible to parasites and may require more frequent deworming.
- Pasture Management: Horses on well-managed pastures with regular manure removal may need less frequent deworming.
- Fecal Egg Count (FEC): Regular FEC tests help determine the parasite load in your horse and guide deworming decisions.
Strategic Deworming: A Modern Approach
Strategic deworming involves using FEC tests to tailor deworming schedules. This approach focuses on:
- Reducing Resistance: Overuse of dewormers can lead to resistance. Strategic deworming helps mitigate this risk.
- Targeting Treatment: Treat only when necessary, based on FEC results, to maintain effective parasite control.
Recommended Deworming Schedule
While each horse’s needs are unique, a general guideline is:
- Foals and Young Horses: Deworm at 2-3 months, then every 2-3 months until they are one year old.
- Adult Horses: Conduct FEC tests every 6 months. Deworm if the count is high (more than 200 eggs per gram).
- Senior Horses: Older horses may have different immune responses; consult a veterinarian for tailored advice.
Practical Example: Implementing a Deworming Plan
Consider a stable with mixed-age horses. Implementing a strategic deworming plan might look like this:
- Conduct FEC tests twice a year for all horses.
- Deworm horses with high egg counts.
- Use different classes of dewormers to avoid resistance.
- Maintain records of deworming and FEC results for each horse.

People Also Ask
How Do I Know If My Horse Needs Deworming?
Conducting a fecal egg count test is the most reliable way to determine if your horse needs deworming. This test measures the number of parasite eggs in your horse’s feces, helping you decide on treatment.
Can Over-Deworming Harm My Horse?
Yes, over-deworming can lead to resistance, making parasites harder to control. It can also disrupt the natural balance of gut flora, potentially causing digestive issues.
What Are the Signs of a Strongyle Infestation?
Signs include weight loss, poor coat condition, colic, and diarrhea. If you notice these symptoms, consult a veterinarian for advice and possible fecal testing.
How Can I Prevent Strongyle Infestations?
Good pasture management, regular FEC testing, and strategic deworming are key. Remove manure regularly and rotate pastures to minimize parasite exposure.
Are Natural Deworming Methods Effective?
Some natural methods, such as herbal supplements, claim to reduce parasites. However, scientific evidence supporting their effectiveness is limited. It’s best to consult a veterinarian before trying alternative methods.
Conclusion
Strategic deworming is essential for effective parasite control in horses. By considering factors such as age, pasture conditions, and fecal egg counts, you can tailor a deworming plan that minimizes resistance and maximizes your horse’s health.
