Buying Guide
How to choose the right worming pour-on for cattle requires considering parasite pressure, herd size, and administration practicality. Below are practical decision points to help compare options:
- Active ingredient: Ivermectin-based products are common and cost-effective for broad internal parasite control. Milbemycin-based products (like Cydectin) offer broader external parasite coverage. Choose based on the parasite profile on your farm.
- Volume and packaging: Larger bottles reduce refills for big herds but are heavier to handle. Match bottle size to herd size and treatment frequency.
- Visible dosing aids: Some formulas include dyes or markings to show which animals have been treated. This helps with batch tracking and reduces double-dosing risk.
- Species and age range: Confirm suitability for the cattle types on your operation (beef vs. dairy) and ensure label instructions cover your animal age groups.
- Resistance and rotation: Rotate between active ingredients if you treat repeatedly to mitigate resistance development. Follow veterinary guidance for rotation plans.
- Administration considerations: Pour-on products require careful application along a clean, dry back line. Weather conditions and handling facilities can influence efficacy and safety.
