Zolvix Plus Challenge FAQ's

: There is widespread resistance to all older active ingredients, including moxidectin and two-, three- and four-way combinations.¹Any reduction in drench efficacy has a direct impact on the health and productivity of your sheep throughout the year. Even a small reduction in drench efficacy can reduce potential income by 2-10%.²That’s why we’ve created the Zolvix Plus Challenge – if you don’t know the resistance status of your flock, you can find out this season by completing a free DrenchCheck worth $282 as part of the Zolvix Plus Challenge.
: To take part in the Zolvix Plus Challenge, simply:
Register online above before your next planned drench.
Your local Elanco representative will contact you to discuss your current program and provide directions on how to conduct a DrenchCheck.
You will receive two Elanco Worm Test kits, (either directly from your Elanco representative or posted), each containing 10 sample jars, gloves, order/authorisation form and a pre-paid Express Post bag.
Use the first kit to collect 10 faecal samples before drenching and dispatch to the testing laboratory using the pre-paid Express Post bag.
Use the second kit to collect 10 faecal samples 10-14 days after drenching and dispatch to the testing laboratory using the pre-paid Express Post bag.
Your local Elanco representative will contact you to discuss the results and to provide recommendations on how to maintain or increase the effectiveness of your drenching program. Then you will know if your current drench is really working or not.
: A DrenchCheck is a simple way to indicate the efficacy of your existing drench against the worm burden in your sheep at the time of testing. A DrenchCheck involves conducting two Worm Egg Count (WEC) tests to determine the reduction in the worm egg count after drenching. The first test is conducted before drenching. The second test is conducted 10-14 days after drenching.
Watch this video to learn how to conduct a DrenchCheck.
: The DrenchCheck kits are being provided Free of Charge. The aim of the Zolvix Plus Challenge is to encourage sheep producers to test the efficacy of a drench in their current drench program – no matter what drenches are being used.
: There is no obligation to purchase Zolvix Plus. Once the results of the DrenchCheck are available, your local Elanco representative will contact you to discuss the results and provide recommendations on how to maintain or increase the effectiveness of your drenching program.
: Your privacy protection is outlined in the Terms and Conditions and on the form used for data collection with the samples. De-identified results may be used to illustrate regional trends.
: Elanco is encouraging the incorporation of diagnostic testing regardless of the drenches you are currently using in your program. This is an opportunity to assess the effectiveness of your current drench regime.
: Yes, performing a DrenchCheck before and after using Zolvix Plus will provide invaluable information into the efficacy of this product against the worm population on your property.

Good agricultural practice is essential for optimal worm control. Resistance may develop to any chemical. Ask your local veterinary practitioner or animal health advisor for recommended parasite management practices for your area to reduce development of resistance. It is advisable that a resistance test be conducted before any parasite treatment is used. Use in accordance with the registered label directions and regional drench decision guidelines (www.wormboss.com.au).
