Choosing the right dewormer for a pregnant mare is crucial for ensuring both the mare’s health and the well-being of the developing foal. It’s important to select a dewormer that is safe during pregnancy and effective against common equine parasites. Consulting with a veterinarian is the best approach to tailor a deworming program specific to your mare’s needs.
What Factors Should Be Considered When Choosing a Dewormer for a Pregnant Mare?
When selecting a dewormer for a pregnant mare, several factors should be considered to ensure safety and effectiveness:
- Safety for Pregnancy: Always choose a dewormer labeled safe for pregnant mares. Commonly recommended options include ivermectin and pyrantel pamoate.
- Parasite Control: Identify the parasites prevalent in your area or stable. Different dewormers target specific parasites such as strongyles, roundworms, or tapeworms.
- Veterinary Guidance: A veterinarian can perform fecal egg counts to determine the parasite load and recommend the most appropriate treatment.
- Timing: Deworming schedules should align with the mare’s gestational timeline, typically avoiding administration in the first trimester unless necessary.
Which Dewormers Are Safe for Pregnant Mares?
Here is a comparison of commonly used dewormers and their safety for pregnant mares:
| Dewormer Type | Active Ingredient | Safe for Pregnant Mares | Targeted Parasites |
|---|---|---|---|
| Ivermectin | Ivermectin | Yes | Strongyles, roundworms, bots |
| Pyrantel Pamoate | Pyrantel | Yes | Roundworms, tapeworms |
| Fenbendazole | Fenbendazole | Yes | Strongyles, pinworms |
| Moxidectin | Moxidectin | Consult Vet | Strongyles, bots |
Note: Always consult your veterinarian before administering any dewormer to ensure it aligns with your mare’s specific health needs.
How Often Should You Deworm a Pregnant Mare?
Deworming frequency can vary based on several factors, including the mare’s environment, health, and fecal egg count results. Generally, it is recommended to:
- Deworm pregnant mares before breeding and during the last trimester.
- Perform regular fecal egg counts to adjust deworming schedules as needed.
- Use a rotational deworming strategy to prevent parasite resistance.
What Are the Risks of Improper Deworming in Pregnant Mares?
Improper deworming can pose several risks to both the mare and her foal:
- Parasite Resistance: Overuse or incorrect use of dewormers can lead to resistant parasite strains.
- Health Complications: An untreated parasite infestation can lead to poor nutrient absorption, weight loss, and colic.
- Foal Health: Parasites can be transmitted to the foal, affecting its development and health.
Practical Tips for Deworming Pregnant Mares
- Consult Your Vet: Always seek professional advice tailored to your mare’s specific needs.
- Monitor Fecal Egg Counts: Regular testing helps in customizing deworming programs.
- Record Keeping: Keep track of deworming dates, products used, and any reactions observed.
- Stable Management: Maintain clean and dry living conditions to reduce parasite exposure.

What Dewormers Are Not Safe for Pregnant Mares?
Some dewormers, such as those containing moxidectin, should be used with caution or avoided in pregnant mares unless specifically recommended by a veterinarian. Always check the product label and consult with a vet.
Can Deworming Affect the Foal?
Deworming with approved products is generally safe and beneficial, as it helps prevent the transmission of parasites to the foal. However, inappropriate use can lead to complications, highlighting the importance of veterinary guidance.
When Is the Best Time to Deworm a Pregnant Mare?
The best times to deworm a pregnant mare are before breeding, during the last trimester, and shortly after foaling. This schedule helps control parasite loads effectively while minimizing risks.
How Can I Tell If My Mare Needs Deworming?
Signs that your mare may need deworming include weight loss, a dull coat, and colic symptoms. Regular fecal egg counts provide a more accurate assessment of parasite burdens.
What Are the Benefits of Rotational Deworming?
Rotational deworming helps prevent parasite resistance by varying the active ingredients used. This strategy ensures a broader spectrum of parasite control and maintains efficacy.
In conclusion, choosing the right dewormer for a pregnant mare involves careful consideration of safety, effectiveness, and timing. By working closely with a veterinarian, you can develop a deworming program that supports the health of both the mare and her foal.
