Dosage and administration
Administration in drinking water.
In chickens (broilers, pullets, layers, and breeder hens) and turkeys, the posology is: 20 mg amprolium / kg body weight / day (equivalent to 0.5 mL of oral solution / 10 kg bodyweight/day) for 5 to 7 consecutive days.
For the preparation of medicated water, the body weight of the animals to be treated and their actual daily water consumption should be taken into account. Consumption may vary depending on factors like age, state of health, breed, and husbandry system. To provide the required amount of veterinary medicinal product in ml per litre drinking water the following calculation should be made:
0.05 mL of the product per kg bodyweight
x average bodyweight (kg) of the animals to be daily treated
x number of animals
= mL of oral solution/.... Litre of drinking water
Total water consumption (L) of the herd at the previous day
Sufficient access to the system of water supply should be available for the animals to be treated to ensure adequate water consumption. No other source of drinking water should be available during the medication period. Medicated drinking water should be replaced every 24 hours.
After the end of the medication period the water supply system should be cleaned appropriately to avoid intake of sub-therapeutic amounts of the active substance.
The veterinary medicinal product should not be used in contact with metal pipework or containers.
