Isolation: Yard
When new animals first arrive, treating them for worms and then yarding them for 48 hours is recommended in order to minimise pasture contamination with potentially-resistant worm eggs.
Fluke eggs can be shed for three weeks after treatment, so after moving off the yard, avoid keeping animals on wet or boggy ground.
Or a gold-standard quarantine protocol could include two treatments with this product six weeks apart, followed by a three-week wait, before joining the main flock at pasture.
