When can your horse go back out to pasture?

After a deworming treatment: pay attention to pasture management!

Effective parasite control doesn’t stop with giving the treatment. Proper pasture management is essential to prevent reinfection and resistance.

Why wait?
In the first 24 hours after administration, the dewormer is excreted through manure. Most horses can return to pasture after 24 to 48 hours.
Note: products containing moxidectin (such as Equest) require a longer waiting period of at least 72 hours.

Remove manure
After treatment, manure still contains active substances and possibly worm eggs or larvae. If left behind, it increases the parasite load on the pasture and disrupts beneficial insects like dung beetles.

Follow-up test after 14 days
Send in a manure sample 14 days after treatment for a follow-up test. This helps determine whether the treatment was effective and prevents unnecessary deworming.

This way, you protect not only your horse but also others sharing the pasture.
