Stomach worm control - Anthelmintic groups


Parasite control is largely based on suppression of the parasitic burden using anthelmintic products. Sheep Specialist Damian Costello, outlines the five anthelmintic classes that we rely on for the control of stomach worms.

Internal parasites, in particular gut worms, are a major challenge to sheep production systems. Parasite control is largely based on suppression of the parasitic burden using anthelmintic products. Nationally anthelmintic resistance i.e. the ability of parasites to survive a dose that should kill them, is increasing for the 3 most common products we use for control; namely, group 1-BZ (white), group 2-LV (yellow) and group 3-ML (clear).
