What Causes Parasite Issues in Horses?
Parasites thrive in grazing environments, spreading through manure and contaminated pastures. Left unchecked, they can cause weight loss, dull coats, colic, or poor performance.
Corro Team Riders see the importance firsthand:
Show Jumper Hunter Holloway manages horses under heavy travel stress, while Reiner Josh Tishman focuses on keeping performance horses strong during demanding schedules. Their experience helps guide Corro’s dewormer picks.
How Dewormers Can Help
Research in Veterinary Clinics of North America: Equine Practice (2003) showed that frequent, routine deworming puts pressure on parasites to develop resistance, while more targeted approaches help maintain horse health.
Another trial in Veterinary Parasitology (2001) confirmed that ivermectin paste stayed highly effective with over 99% reduction against strongyles, bots, and other gastrointestinal parasites in horses.
These studies reinforce what riders and vets already practice: trusted ingredients like fenbendazole and ivermectin remain the backbone of parasite control, keeping horses healthy, shiny, and ready for the work they love. They’re also a key part of overall Health & Recovery product portfolio, the bigger picture of keeping every horse feeling their best.
Choosing The Right Dewormer
Dewormers aren’t one-size-fits-all. Your horse’s age, lifestyle, and workload all play a role. Young horses often need stronger coverage, while seniors and performance horses do best with carefully timed treatments to protect weight, digestion, and energy. Everyday companions thrive with budget-friendly pastes that make routine care easy.
Here’s how to match them up:
- Performance horses → Vet-recommended gel for full coverage
- Senior horses → Power packs for digestive resets
- Everyday companions → Affordable pastes for routine care
