Dose Calculation
The dose for Exzolt is 0.5 mg fluralaner per kg BW per day (equivalent to 0.05 mL Exzolt) administered twice, 7 days apart. The complete course of therapy must be administered for full therapeutic effect.
Determine the duration of time (between 4 and 24 hours) over which to administer the medicated water on the treatment day. This period must allow all birds to receive the required dose. Estimate how much water birds will consume during treatment based on their water consumption during the same period the day before start of treatment.
Next, calculate the needed volume of Exzolt, based on the total weight of the birds in the house to be treated. To ensure administration of the correct dose, body weight should be determined as accurately as possible and a sufficiently accurate measuring device should be used. The required amount of Exzolt on each treatment day should be calculated from the total body weight (kg) of the entire group of chickens to be treated, using the following formula:
mL product/treatment day = Total body weight (kg) of chickens to be treated × 0.05 mL

Pump Considerations
Dosing pumps offer very interesting possibilities in therapeutics, allowing prompt action in targeting the treatment of a room, a pen, or a batch of animals, and the flexibility to alter the medication, or even adjust the dose, during a course of treatment.
The use of dosing pumps for administering medications requires adherence to Good Practice standards to maximize the accuracy of dosing, which:
- Reduces the overuse of medications.
- Limits the risk of developing resistance.
- Eases conformity with withdrawal times and maximum residue limits in meat, offal, and eggs.
The distribution of drugs via drinking water using dosing pumps requires a homogeneous active ingredient, which dissolves or mixes well, reliable equipment, and a well-regulated water flow at the level of the drinkers.
During the use of dosing pumps, it is absolutely essential to check the:
- Flow of water through the drinkers.
- Cleanliness of the tank.
- State of the dosing pump.
- Valves governing the distribution of the water to each room or pen.
