"Users report the Parasight System FEC Kit is fast, accurate and well-suited for repeated fecal egg counts, with an intuitive workflow; downsides noted are higher upfront cost and a short learning curve. Overall it's favored by clinics and labs needing reliable automated counts."

BEST FECAL SAMPLE COLLECTION SUPPLIES

BD Gaspak EZ Container Systems

BD Gaspak EZ Container Systems

BD Gaspak EZ Container Systems are market-leading when anaerobic integrity is required, offering sealed container systems and gas-generating sachets that preserve obligate anaerobes for culture and sensitivity testing. Technically these containers provide a unique advantage over open-cap vial systems, making them indispensable for microbiology labs focused on accurate culture recovery, though they are more expensive and less necessary for molecular-only workflows. When preserving organism viability during transport is a priority, BD’s proven packaging reduces failed cultures and the hidden costs of repeat sampling.

BEST DIGESTIVE SUPPORT AND PROBIOTIC SUPPLEMENTS

Webber Naturals Probiotic + Prebiotic

Webber Naturals

Webber Naturals Probiotic + Prebiotic earns its market‑leader placement by combining live microbial strains with prebiotic fiber into a single synbiotic formula, simplifying a post‑deworming regimen by delivering both recolonization agents and microbial fuel. Compared with bulk prebiotic powders and fermented whole‑food mixes on this list, it offers convenient dosing and generally lower per‑dose cost than premium clinical blends, though it lacks the organic whole‑food profile of some powdered options.

BEST PASTURE AND MANURE MANAGEMENT SUPPLIES

Faulkner's ATV Chain Harrow 4x4

Garvee

Faulkner's ATV Chain Harrow 4x4 is the best-in-class choice for small to mid-sized operations that need fast pasture leveling and seedbed preparation using an ATV; its compact chain-and-spring design delivers broad coverage per hour at a lower capital outlay than tractor-mounted drags like the Tarter. Because it reduces manual labor and operating costs relative to hand tools, it’s especially cost-effective for hobby farms and pairs well with compost accelerators to speed pasture recovery after aeration or spreading.

Scientific Evidence Behind Strategic Deworming

Contemporary research supports targeted and monitored parasite control rather than routine blanket treatments. Studies in veterinary parasitology and equine medicine show that regular fecal egg count (FEC) monitoring, selective treatment of high shedders, and occasional fecal egg count reduction tests (FECRT) to assess anthelmintic efficacy slow resistance development and reduce overall drug use. The concept of 'refugia' — maintaining a population of drug-susceptible parasites — is widely recommended as part of resistance management. Complementary measures such as pasture rotation, manure management and nutritional support further reduce infection pressure and improve immune resilience.

Fecal egg count (FEC) monitoring: Multiple peer-reviewed studies demonstrate that FEC-based selective treatment reduces total anthelmintic treatments by treating only high shedders and vulnerable individuals.

Fecal egg count reduction test (FECRT): The FECRT remains the standard method to detect decreased anthelmintic efficacy and identify emerging resistance in common equine parasites.

Refugia and rotation strategy: Research supports maintaining refugia and using strategic rotation of drug classes informed by FECRT results to slow resistance development, rather than routine calendar-based deworming.

Integrated control: Combining diagnostics with pasture management (mowing, manure removal, rotational grazing) significantly lowers larval contamination on pasture and complements chemical control.

Adjunct nutritional support: Studies indicate that balanced nutrition and targeted supplements (digestive support, antioxidants, trace minerals) enhance immune function and recovery, but do not replace anthelmintics.

Canadian context: Regional studies and veterinary surveys in Canada highlight growing anthelmintic resistance concerns and increased adoption of FEC-based protocols and veterinarian-guided plans across provinces.

Frequently Asked Questions

Is an ivermectin paste a good baseline for routine horse deworming?

Ivermectin-based pastes are a common baseline in many equine deworming programs because ivermectin is effective against a broad range of nematodes (roundworms) and bots and is given as a single oral dose. Rather than deworming on a fixed calendar, base product choice and timing on fecal egg count results and your veterinarian's guidance.

What parasites do the main horse dewormer actives target?

Ivermectin is effective against many nematodes and bots. Moxidectin has a broader spectrum that also reaches encysted small strongyle larvae. Praziquantel is added in combination products to treat tapeworms, while fenbendazole and pyrantel cover other nematodes. Confirm the label indications and consult your veterinarian to match the active to the parasites present in your horse.

How should I choose a dewormer for the best value?

The most cost-effective approach is targeted deworming: use fecal egg counts to identify high shedders and treat based on results instead of deworming every horse on a fixed schedule. This reduces wasted product and slows resistance. Match the active ingredient to the parasites confirmed by testing and follow your veterinarian's advice.

How do I monitor for anthelmintic resistance in my herd?

Use a fecal egg count reduction test (FECRT): run a fecal egg count before deworming and again about 10 to 14 days after, then compare the reduction against the expected efficacy for that drug class. Persistently low reductions can signal emerging resistance. Fecal egg count kits and automated counting platforms make repeat counts faster and more consistent.

Conclusion

In Canada the shift toward targeted, evidence-based parasite control is driven by veterinary guidance, regional climate differences and concern about resistance. We hope this overview helped you find the right mix of dewormers, fecal testing tools, supplements and strategic protocols for your herd. Use the site search or filters to refine by active ingredient, product type, herd size, resistance status or veterinarian rating to expand or focus your results — and consult your veterinarian when implementing changes.
