WEC testing indicates the level of worms affecting your animals. With this information, you can make informed choices about treatment, livestock grazing and prevent pasture contamination for future grazers.

Without WEC testing, you may treat animals when it's not needed. Alternatively, you may not treat them because they appear healthy. By the time stock look like they need treatment, the damage and lost production has already occurred.

Regular WEC testing helps you treat at the right time and improves production outcomes.

By using WEC testing to understand the parasite burden in your animals, you can adjust treatment timing based on evidence. Instead of sticking to a schedule set by your calendar, you treat animals when it's necessary.

Standard oral drench usually has a kill time of 24-48hrs. Assuming it has worked, once that drench has cleaned out the parasite burden stock start eating parasite larvae from pasture again – re-starting the cycle of parasite burden. It’s important to limit the larvae animals are ingesting. WEC testing helps understand the larval challenge on each paddock.

By WEC testing after treatment, you can ensure that your investment in drench has killed the parasites in your animals. Post-treatment WECs for sheep should be undertaken 10 days after drenching, and for cattle 14 days post treatment.
