For use in drinking water.
To ensure administration of the correct dose, body weight should be determined as accurately as possible.
Before allowing animals to have access to the medicated water, the water delivery system should be drained, if possible, and flushed with the medicated water to ensure accuracy of dosing. This procedure may need to be performed on all treatment days.
The dose is 2.5 mg fenbendazole per kg body weight per day (equivalent to 0.0125 ml Pigfen oral suspension per kg body weight per day). This dose has to be administered on 2 consecutive days.
Dose calculation:
The required daily amount of product is calculated from the total estimated body weight (kg) of the entire group of pigs to be treated. Please use the following formula:
ml product/day = total estimated body weight (kg) of pigs to be treated x 0.0125 ml
For each treatment day the medicated water needs to be freshly prepared.
Follow the instructions described below to prepare the medicated water. Use a sufficiently accurate commercially available measuring device.
For use in medication tank:
Add the calculated amount of product to the volume of drinking water usually consumed by the animals over 6 hours. Stir until content in the medication tank is visibly homogeneous. The medicated water appears hazy. No further stirring during administration is necessary.
For use in dosing pump:
Add the calculated amount of product to the unmedicated water in the stock suspension container of the dosing pump. The volume of unmedicated water in the stock suspension container has to be calculated taking into account the preset injection rate of the dosing pump and the volume of drinking water usually consumed by the animals over 6 hours. Stir until content in the stock suspension container is visibly homogeneous. The medicated water appears hazy.
During treatment all animals must have solely but unrestricted access to the medicated water.
During treatment, after complete consumption of the medicated water, animals must be allowed access to un-medicated drinking water as soon as possible.
Ensure that the total amount of medicated water offered is consumed.
