Worming Rotation Programs for Cattle & Sheep in Australia (Kilverm, Ivermectin & Triclamec Guide)
Effective parasite control in cattle and sheep requires more than just a single product. Australian livestock producers increasingly use worming rotation programs to help manage parasite resistance and maintain long-term herd and flock health.
This guide explains how different worming classes such as levamisole (Kilverm), ivermectin (Ivermec range), and combination drenches (Triclamec Ultra) fit into a structured parasite management program.

Why Worming Rotation Is Important
Parasite resistance is one of the biggest challenges facing Australian livestock producers. Over time, repeated use of the same chemical class can reduce effectiveness against internal parasites.
Rotating between different drench groups helps maintain long-term effectiveness and supports sustainable livestock production systems.
- Reduces risk of parasite resistance
- Maintains effectiveness of drenches over time
- Supports healthier cattle and sheep performance
- Improves long-term pasture and herd management

The Three Main Worming Classes Used in Australia
1. Ivermectin-Based Products (Macrocyclic Lactones)
Ivermectin-based pour-ons are widely used in cattle parasite control programs for internal and external parasite management.
These products are commonly used for lice, mites, worms and external parasite control in cattle.
---
2. Triclabendazole + Combination Products (Dual Active Control)
Combination products provide broader parasite coverage including liver fluke and internal worms.
These are commonly used in programs where liver fluke and multi-stage parasite control is required.
---
3. Levamisole-Based Drenches (Kilverm – Clear Drench Group)
Kilverm is a levamisole-based oral drench used in cattle and sheep for susceptible internal parasites.
This is a different chemical class from ivermectin-based products and is commonly used as part of rotational worming programs.
Kilverm is commonly used for fast-acting worm control in cattle and sheep when rotating away from other drench classes.

Example Worming Rotation Strategy (Simple Guide)
A typical Australian livestock rotation program may alternate between drench classes to reduce resistance pressure:
-
Cycle 1: Ivermectin-based pour-on (Ivermec range)
-
Cycle 2: Levamisole-based drench (Kilverm)
-
Cycle 3: Combination product (Triclamec Ultra where appropriate)
This approach helps maintain long-term parasite control effectiveness in cattle and sheep systems.

Signs of Parasite Burden in Livestock
- Weight loss or poor weight gain
- Reduced feed efficiency
- Dull coat or poor condition score
- Scouring or digestive issues
- Reduced productivity in herds or flocks

Important Note
Always follow label directions, dosing instructions and veterinary guidance when selecting and rotating livestock drenches. Correct dosing and rotation are essential to help maintain drench effectiveness and reduce resistance development.
