Buying Guide: Key Purchase Considerations For Summer Deworming
- Active ingredient and spectrum: Most products rely on ivermectin at 1.87% as a broad-spectrum option for internal parasites, including bots and arterial stages of S. vulgaris. Check for additional protections if your pasture or rotation exposes horses to other parasite types.
- Dosing and administration: Flavored pastes (apple flavor) and calibrated syringes simplify dosing accuracy and compliance, especially for younger or skittish horses. For groups, multi-pack formats help maintain consistent schedules.
- Format and packaging: Choose formats that fit your operation size—single-tube for travel or shows, multi-tube packs for barns, or liquid formulations for flexible mixing with feed or water where appropriate.
- Age and weight considerations: Some products specify effective coverage up to certain weights (e.g., up to 1250 lb). Ensure dosing matches the weight range of your horses or use weight-based dosing guidance from the product.
- Flavor and palatability: Flavors can improve acceptance, reducing resistance during administration in summer heat or after exposure to pasture parasites.
- Administration environment: Liquid formulations may require mixing, while pastes provide quick, direct dosing. Consider your barn workflow and patient comfort when selecting a product.
- Manufacturing standards and labeling: Look for reputable brands with clear dosing instructions, expiration information, and safety guidance to ensure reliable performance in summer parasite control.
- Rotation and resistance management: Do not rely on a single product year-round. Rotate active ingredients and adhere to integrated parasite management practices, including pasture management and routine fecal egg counts when possible.
- Safety and handling: Follow packaging safety instructions, particularly for handling concentrate pastes and ensuring the correct dosage to avoid underdosing or overdosing.
