Equine Parasite Management and Welfare

Gastrointestinal parasites cause significant welfare problems in horses; evidence-based targeted treatment programmes protect horses while reducing resistance development.

Key Facts

Cyathostomes (small strongyles) are the most clinically significant horse parasite causing larval cyathostominosis
Targeted selective treatment based on faecal egg counts reduces unnecessary anthelmintic use
Anthelmintic resistance is developing in equine parasites following years of routine calendar dosing
Pasture management through resting and harrowing reduces environmental larval burden

Welfare Considerations

Equine parasite management exemplifies the evolution from routine calendar treatment toward evidence-based targeted treatment. Calendar dosing without monitoring has driven anthelmintic resistance while treating horses that may not need treatment and failing to identify those with high burdens. Targeted selective treatment based on faecal egg count monitoring directs treatment where it is needed, maintains anthelmintic efficacy, and protects welfare through accurate identification of high-burden animals requiring intervention.

What You Can Do

Implement targeted selective treatment based on faecal egg count monitoring rather than calendar dosing
Work with your vet to develop a parasite management strategy appropriate for your horse
Use pasture management techniques to reduce environmental larval burden
