Donít forget to treat cattle for fluke at grazing this season
1 May 2013
Despite the cold winter this year, liver fluke is
still likely to be a problem on many farms this grazing season warns the
COWS industry stakeholder group.
Any wet areas in fields can provide a habitat for the
snail intermediate host and increase the risk of fluke infection. Such
pastures should be avoided but if this is not possible, cattle grazing
on high risk pastures may need to be dosed with a flukicide between 10
to 12 weeks after turnout. "This will reduce fluke egg output and
therefore lessen the risk of infection later in the season, as well as
improve performance at grass" explains, veterinary consultant Dr Dermot
Mackie, of the COWS group.
All categories of cattle may require treatment
depending on local risk factors and prevailing weather conditions.
Products active against adult fluke can be used at any time of the year
but those containing triclabendazole should be used in preference in
late summer or early autumn, when immature fluke are often present.
Combination fluke and worm products should only be
used when burdens of roundworms and fluke are likely to be present
simultaneously. The decision to use combination treatments should be
based on knowledge of the parasitesí epidemiology supplemented with the
use of diagnostic worm egg counts. All treatment choices should be made
with the advice of your veterinary surgeon or suitably qualified person.
Also keep in mind the meat/milk withdrawal periods for beef and dairy
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
