Introduction to Horse Worming

Why Worming Is Crucial

Think of internal parasites as silent invaders. They're easy to overlook until your horse starts showing signs like weight loss, colic, or a dull coat. Worming keeps these pests in check and your horse in peak condition.

Common Internal Parasites in Horses

Horses can play host to a variety of parasites — here are the most common culprits:

Roundworms (Ascarids)

Mostly affecting young horses, roundworms can lead to blockages and stunted growth if not addressed early.

Tapeworms

These attach to the gut lining, potentially causing colic and poor nutrient absorption.

Bots

Botflies lay eggs on your horse’s coat; once ingested, they develop into larvae in the stomach.

Strongyles

The worst offenders, especially large strongyles, which migrate through organs and can cause severe damage.

Types of Horse Wormers

Oral Pastes and Gels

These are the most popular form of wormers. Easy to administer and available in pre-measured syringes.

Granules and Feed-Through Wormers

Ideal for picky eaters, these are mixed with feed for stress-free administration.

Injectable Wormers

Less commonly used, injectables are typically administered by vets for specific cases.

Active Ingredients and Their Uses

Let’s break down the main active ingredients you’ll find in wormers and what they target:

Ivermectin

Kills a broad spectrum of parasites including bots and strongyles.

Moxidectin

Similar to ivermectin but with longer residual activity. Effective against encysted small strongyles.

Fenbendazole

Great for targeting roundworms and encysted strongyles. Often used in a 5-day PowerPac form.

Pyrantel Pamoate

Effective against roundworms and tapeworms when used at double doses.

Praziquantel

Specialized for tapeworm control. Often combined with ivermectin or moxidectin.

The Importance of Rotational Deworming

Avoiding Resistance

Using the same wormer repeatedly? That’s like giving parasites a free training session. Rotating wormers based on active ingredients helps prevent resistance.

Seasonal Deworming Schedules

Most horses are dewormed every 8 to 12 weeks, but this can vary. Use fecal egg counts to guide your deworming schedule based on actual need rather than guesswork.

Prescription vs. Over-the-Counter Wormers

What’s the Difference?

OTC wormers are effective but come with limitations. Prescription wormers may offer broader coverage or treat specific infestations.

When to Consult a Vet

If your horse is losing weight, has colic symptoms, or you're unsure about resistance issues, talk to your vet. They may recommend fecal testing or targeted treatments.

If your horse shows these signs, it's probably time to check for parasites.

Conclusion

Choosing the best wormer for your horse isn't about picking a fancy label—it's about understanding your horse's needs, knowing what parasites you’re dealing with, and making informed choices. By rotating wormers, monitoring fecal egg counts, and working closely with your vet, you’ll keep your horse healthy, happy, and parasite-free.
