Liver fluke risk lower than last year
7 November 2014
The relatively dry autumn this year has meant that
the liver fluke risk is lower than it was
for last year.
Therefore in low risk areas, such as much of England
and Wales, fluke
treatments for cattle need not be based on products with
triclabendazole as the active ingredient. Instead treatments can be
based on products containing closantel or nitroxynil, which only kill
older immature fluke. These products can either be given at housing and
then repeated if required, or delayed until 6-8 weeks after housing.
Similarly, products that only kill adult fluke such
as clorsulon, oxyclozanide and albendazole could be used around housing
time and then again three months later if necessary. Using products
other than triclabendazole will help reduce any selection for resistance
that could occur in herds that rely on this product routinely.

COWS stresses that no
flukicide has persistent action and allowing cattle onto fluke-infected
pasture after treatment immediately re-exposes them to the risk of
As with all anthelmintic treatments, it is imperative
that animals are dosed according to their liveweight. Read the
information leaflet in the pack and follow dosing instructions
