How to prevent parasite infections in horses

by | Jan 5, 2024

Preventing worms and other parasitic infections in horses is crucial for their health and well-being. Here are some general guidelines to help you learn how to prevent parasite infections, and manage and reduce the risk of infestations in horses:

Regular Deworming:

Work with your veterinarian to create a strategic deworming schedule based on your horse’s age, health, and environment.
Rotating dewormers helps prevent resistance. Your vet can advise on the most effective products for your situation.

Fecal Egg Counts:

Perform regular fecal egg counts to determine the level of parasite burden in your horse. This helps tailor the deworming program to your horse’s specific needs.

Pasture Management:

Practice rotational grazing to reduce the risk of pasture contamination.
Remove manure from paddocks regularly to break the parasite life cycle.

Quarantine New Horses:

Quarantine new horses for at least 21 days to prevent introducing new parasites to your property.

Proper Nutrition:

Ensure your horse receives a balanced and nutritious diet with adequate forage. A healthy immune system can better resist worm infestations.

Maintain a Clean Environment:

Keep stables, stalls, and feeding areas clean to minimize the risk of contamination.

Manure Management:

Compost manure properly to kill parasite eggs. Avoid spreading fresh manure on pastures.

Avoid Overcrowding:

Overcrowded conditions increase the risk of parasite transmission. Provide adequate space for each horse, we recommend 1 acre per horse for grazing to avoid over-stressing your pasture.

Strategic Grazing Practices:

Avoid overgrazing, as this can lead to horses ingesting more parasites. Rotate pastures when possible.

Monitor for Signs of Infestation:

Be vigilant for signs of worm infestation, such as weight loss, colic, diarrhea, or a dull coat. Early detection can lead to prompt treatment.

Regular Veterinary Check-ups:

Schedule routine veterinary examinations to monitor your horse’s health and discuss any concerns about parasites.


Always consult with your veterinarian to create a tailored deworming program based on your horse’s specific needs and local conditions. Regular communication with your vet and following their advice about how to prevent parasite infections will contribute to the overall health and well-being of your horses.
