What Farmco Recommends It For:
Trifecta suits sheep and cattle producers needing serious worm control plus a trace mineral lift. Plus, it’s a smart pick for properties dealing with ML, BZ, or LEV resistance in sheep, or ML resistance in cattle. Additionally, it supplements diets that may be deficient in selenium and cobalt. So reach for it when one mob covers two species and you want broad-spectrum results.
Why It’s a Farmco Favourite:
Firstly, Trifecta is a triple-active oral drench combining abamectin, levamisole, and oxfendazole. Secondly, it adds supplemental cobalt and selenium for nutritional support. Plus, it works across both sheep and cattle — a real bonus for mixed enterprises. Furthermore, it’s backed by the trusted Coopers name in Australian animal health. As a result, it’s a versatile, hard-working tool for the modern livestock operation.
Coopers Trifecta is a powerful triple combination drench developed for sheep and cattle. Moreover, it pairs three actives across three drench families — abamectin (ML), oxfendazole (BZ/white), and levamisole hydrochloride (clear). Therefore, you target worms across three modes of action in one dose. Additionally, every dose delivers supplemental cobalt and selenium to support flock and herd health. As a result, you cover worm control and mineral support in a single run through the yards.
Drench resistance is a serious challenge in Aussie flocks and herds. Fortunately, Trifecta controls sheep worms with single, double, or triple resistance to ML, BZ, or LEV families — provided they’re sensitive to at least one active. Plus, it controls cattle worms resistant to the ML drench family. Therefore, you stay one step ahead of resistance pressure on both sides of the fence. As a result, you protect today’s productivity and tomorrow’s drenching options.
Trifecta is brought to you by Coopers, a respected name in Australian animal health for generations. Furthermore, the formulation is backed by serious research and field-proven Aussie performance. As a result, you can drench with confidence using a treatment trusted by sheep and cattle producers nationwide.
Dosage Chart
Administer orally at 1mL per 10kg bodyweight using accurate drenching equipment. Shake well before use.
| Species | Dose Rate | Re-treatment Interval |
|---|---|---|
| Sheep | 1mL per 10kg liveweight | Do not retreat for 28 days |
| Cattle | 1mL per 10kg liveweight | Do not retreat for 28 days |
Weigh the heaviest animal in each group and dose the mob to that weight. For cattle, draft into two or more lines where there’s a wide variation in liveweight to avoid overdosing. Check drenching equipment before and during use. Do not use in lambs under 15kg or 6 weeks of age, or calves under 100kg or 16 weeks of age.
