a dose rate of 5 mg fenbendazole per kg bodyweight.
May be administered to pigs either as a single dose of 5 mg/kg (migrating larval,
intestinal larval and adult stages) or by divided dose of 0.72 mg/kg over 7 days
(intestinal larval and adult stages) or 0.36 mg/kg over 14 days (intestinal larval and
adult stages).
Single dose treatment
Use the following formula to calculate how much veterinary medicinal product to add
per tonne of feed:
Kg = Bodyweight (kg)
veterinary medicinal product per tonne (Daily feed intake (kg) x 8)
7 day treatment
The standard dose rate can be divided and administered in feed over 7 days. Use the
following formula to calculate how much veterinary medicinal product to add per
tonne of feed:
Kg = Bodyweight (kg)
veterinary medicinal product per tonne (Daily feed intake (kg) x 56)
14 day treatment
The standard dose rate can be divided and administered in feed over 14 days. Use
the following formula to calculate how much veterinary medicinal product to add per
tonne of feed:
Kg = Bodyweight (kg)
veterinary medicinal product per tonne (Daily feed intake (kg) x 112)
To ensure a correct dosage, body weight should be determined as accurately as
possible. If animals are to be treated collectively rather than individually, they should
be grouped according to their bodyweight and dosed accordingly, in order to avoid
under- or overdosing.
The intake of medicated feed depends on the clinical condition of the animals. In
order to obtain the correct dosage, the concentration of fenbendazole may need to
be adjusted accordingly.
For incorporation into dry feed at the registered mill.

•
misadministration of the veterinary medicinal product, or lack of calibration of
the dosing device (if any).
Suspected clinical cases of resistance to anthelmintics should be further investigated
using appropriate tests (e.g. Faecal Egg Count Reduction Test). Where the results
of the test(s) strongly suggest resistance to a particular anthelmintic, an anthelmintic

should be used.
