Zanil fluke drench is an orally administered drench for the treatment and control of liver and rumen fluke (also known as stomach fluke) in cattle and sheep. Zanil is highly effective against adult fluke that are present in the bile duct of the animal. Zanil is appropriate for use on both sheep and cattle all year round, although in housed animals the treatment should be re-administered 8 to 12 weeks later to control the threat of immature fluke that may have been present at the time of housing.
Zanil also boasts a short withdrawal time for dairy cattle.
