More and more Australian farmers are finding that traditional drenches they have been using on
their cattle herds just aren’t working like they used to. What was once considered to be an issue primarily in sheep production is becoming prevalent in cattle as well. “Everywhere the industry has looked they’ve found drench resistance in cattle,” says Managing Director of Herd Health, Dr Richard Shepherd. Efficacy issues have been found in ML (‘mectin’) drenches, which farmers have been using for many years to control parasites in their cattle.
Results from recent field studies1 on more than 30 properties around the country, show that more than 2 out of every
3 properties tested have ML drench efficacy issues.
These studies also found that:
Moxidectin was only effective on 32% of the properties tested.*
Doramectin was effective on just 47% of properties tested.*
However, these field studies found that Eclipse® combination pour-on for cattle was highly effective, even when significant ML (including moxidectin and doramectin) resistance was present. Eclipse has been tested and proven in trials in Australia, to control cattle worm populations even where resistance is present.
The combination of two powerful broad-spectrum actives, abamectin and levamisole (LEV), is the key for Eclipse to provide a more powerful parasite control solution for farmers. Eclipse is the only cattle pour-on endectocide in Australia with a registered label claim to control ML and LEV resistant worms. Farmers already using Eclipse have reported improved weight gains and getting their cattle to market sooner when compared to using their previous single-active drenches.
In fact studies to date1,2 have shown better reduction of egg counts in cattle treated with Eclipse than in those treated with a single-active ML drench. Eclipse was >99% effective at reducing faecal egg and worm counts in infected cattle. Trials1 demonstrated the unsurpassed efficacy of Eclipse against:
ML-resistant Cooperia and Ostertagia compared with doramectin and moxidectin drenches.
Eclipse combination pour-on can deliver increased efficacy over singleactive ML drenches as shown in these field trials. This results in lower faecal egg counts and cleaner pastures with the potential for superior livestock. The presence of drench resistant worms on properties can be reduced by using Eclipse, when compared to using a single-active ML drench.
