COMBINATION DRENCHES ARE THE NEW STANDARD FOR CATTLE
Key cattle worms in Australia are Barber’s Pole Worm, Cooperia, and Ostertagia. The most damaging ones are Barber’s Pole and Ostertagia. Drench resistance in these worms can decrease productivity, and an effective drench is essential to drive good cattle growth.1-7
Label claims of most cattle drenches, including well known brands like Ivomec®, Cydectin®, Dectomax®, Eprinex® and their numerous generics are based on trials condected decades ago.
CURRENT CATTLE DRENCHES AND THEIR GENERICS - ARE THEY WORKING?
| BRAND NAME | YEAR REGISTERED |
|---|---|
| Ivomec® Pour-On | 1994 |
| Cydectin® Pour-On | 1996 |
| Dectomax® Pour-On | 1997 |
| Eprinex® Pour-On | 1998 |
| Sureshot® Duo | 2007 |
| Cydectin® Platinum | 2020 |
CATTLE PRODUCERS CAN NO LONGER RELY ON COMMONLY USED DRENCHES
Cydectin Platinum controls worms no longer killed by drenches such as Cydectin®, Dectomax®, Eprinex®, Ivomec® and their generics1-7.
Cydectin Platinum is a dual-active drench combining the potency and persistency of Moxidectin with the knockdown effect of Levamisole, in a powerful and sophisticated formulation, DMI-Sorb, not replicated by any
other combination cattle drench.
An article published in the Australian Cattle Veterinarian's Journal summarised the results of 25 trials, including over 1,100 animals.1
The table below summarises relevant data from the 25 trials for key worm species.
