Amounts to be administered and administration route
The recommended dose rates are as follows:
Pigs:
10–20 mg/kg bodyweight daily
Chickens:
20-30 mg/kg bodyweight daily
Turkeys:
10-30 mg/kg bodyweight daily
Ducks:
10-30 mg/kg bodyweight daily
These dose rates can usually be achieved by mixing 1.2 kg of Aurofac 250 Granular per tonne of complete feed to give a concentration of 300 ppm chlortetracycline hydrochloride. However, the correct incorporation rate should always be calculated based on the feed consumption rates of the animals to be treated.
To ensure thorough dispersion of the product, it should first be mixed with a suitable quantity of feed ingredients before incorporation into the final mix.
AUROFAC 250 Granular can be incorporated in pelleted feed preconditioned at temperatures up to 70°C.
The medicated feed should be supplied to the affected pen(s) or group(s) of pigs, chickens, turkeys or ducks. Treatment should be continued for a period of five to seven days for respiratory or systemic infections. During the treatment period, only feed medicated with the product should be supplied.
A manufacturer who is approved to incorporate directly at any concentration, veterinary medicinal products or premixtures containing such products must be responsible for mixing when incorporation is less than 2kg per tonne for final feed.
For incorporation into dry feed at the registered mill.
Overdose (symptoms, emergency procedures, antidotes), if necessary
Chlortetracycline is of low toxicity and there is a wide safety margin at the recommended dosage. On rare occasions overdosage may cause diarrhoea and over growth of yeast and fungi. Under such conditions, withdraw medication and apply appropriate treatment.
