What Farmco Recommends It For:
Q-Drench suits sheep producers running strategic drench programs across the season. Plus, it’s ideal for weaning, pre-lambing, quarantine, primer, and exit drenches. Additionally, it’s a smart pick where multiple species of resistant worms are confirmed or suspected. So reach for it when you need maximum efficacy and want to slow the spread of resistance.
Why It’s a Farmco Favourite:
Firstly, Q-Drench is a 4-way combination short-acting drench — four actives working through four different modes of action. Secondly, the additive effect lifts overall efficacy well above any single active. Plus, it’s well-suited to flocks with known ML resistance. Furthermore, it’s backed by Zoetis, a global leader in animal health. As a result, it’s a high-performance, future-proofing tool for the modern sheep enterprise.
Powerful 4-Way Combination Drench
Q-Drench from Zoetis is a short-acting oral drench developed for sheep. Moreover, it combines four actives at four fully effective doses, each with a different mode of action. Therefore, parasites face attack from four directions in a single drench. As a result, you knock down sensitive worms and stack the deck against resistant ones too.
Slows the Spread of Drench Resistance
Combination drenches deliver two big wins. Plus, they boost overall efficacy through the additive effect of the actives. Furthermore, each active helps protect the others from resistance development — if a worm survives one, the next is likely to take it out. Therefore, fewer resistant parasites breed on into the next generation. As a result, you preserve your drench options for the long haul.
Q-Drench is brought to you by Zoetis, a globally respected leader in animal health. Furthermore, the product is backed by decades of veterinary research and field-proven performance. As a result, you can drench with confidence using a treatment trusted by Aussie sheep producers and vets.

Weigh a representative sample before treatment and dose the mob to the heaviest animal in each group. Where there’s a wide range in liveweight, draft into two or more lines to avoid overdosing. Always check dose rates and equipment before drenching commences.
