Curofen 50 mg/g Premix for Medicated Feeding Stuff for Pigs

For oral administration after incorporation into complete feed for pigs. Feed medicated
with this product can be pelleted. Pelleting should not be conducted at temperatures in
excess of 70°C.
The recommended therapeutic dose is 5 mg fenbendazole per kg bodyweight.
To ensure administration of a correct dose, 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.
To achieve this dose:
a) mass/whole herd medication with a single dose (on one day).
Use the following formula to calculate how much Curofen 50mg/g to add per tonne of
feed:
[0.1 g * Curofen 50mg/g / x Average Bodyweight (kg)
Number of treatment days] of treated animals
kg of Curofen/tonne = -------------------------------------------------------------------------
Average daily feed intake (kg)
*For a single treatment, the dose rate is 5 mg of fenbendazole/kg bw, equivalent to
100 mg or 0.1g Curofen 50mg/g kg/ bw.
-
at the rate of 2 kg per tonne of feed.
