Why treat grazing cattle for liver fluke?

Spring pasture has a burden of infective liver fluke larvae that can infect cattle once they are turned out to grass.

After these infective larvae are ingested they make their way to the animal’s liver, where they cause damage as they mature into adult fluke.

Significant numbers of fluke can be present eight-to-12 weeks post turn-out, yet treatment for liver fluke is often delayed until autumn/housing.

As a result many cattle may go untreated for liver fluke for the entire summer.

Cattle at grass, with a developing fluke burden, will have reduced growth rates so treating them during the grazing season will maximise live-weight gain at grass.

Treatment at grass:
  • Removing worm and fluke burdens improves growth rates in grazing cattle.
  • Closantel reduces fluke egg output after treatment, which will in turn reduce infection on pasture heading into the high-risk autumn period.
  • Breaks the liver fluke life-cycle.
  • Cattle are healthier and at less risk of being heavily infected with fluke coming up to housing.

Closamectin Pour On can be used in pregnant maiden dairy heifers during the first half of pregnancy.


This allows for a timely treatment mid-grazing to control fluke and worm burdens and help these valuable heifers reach their target weight at first calving.
