Read this if your horse is losing condition or looks “off” for no obvious reason
Parasites are common and manageable. The win is a repeatable plan: fecal egg counts, smart manure control, and a vet-guided strategy that fits your region and herd.
Intestinal parasites, commonly referred to as worms, are one of the most widespread but preventable threats to equine health. If left unchecked, they can rob your horse of nutrients, contribute to colic risk, and create long-term internal stress.
Types of Common Equine Parasites
- Small strongyles (cyathostomes) - The most common; can encyst in the gut lining.
- Large strongyles - Historically dangerous but now less common due to modern deworming programs.
- Roundworms - Primarily affect foals and young horses.
- Tapeworms - Can contribute to digestive upset and colic risk.
- Pinworms - Can lead to tail rubbing and irritation.
Signs Your Horse Might Have Parasites
- Weight loss or difficulty gaining condition
- Dull, coarse coat
- Diarrhea or inconsistent manure
- Frequent tail rubbing
- Signs of colic or discomfort
- Sluggish behavior or poor performance
Prevention and Management
- Use fecal egg counts to guide a strategic deworming plan
- Rotate pastures and avoid overgrazing
- Remove manure regularly from stalls and turnout areas
- Provide clean, uncontaminated water and feed
- Work with your vet to adjust for regional and seasonal risks
Why It Matters
Parasite control is not just about deworming. It’s about long-term gut health, performance, and prevention. A smart program keeps your horse healthier, reduces unnecessary treatments, and helps your barn run cleaner.
