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 3.0 kg of Aurofac Granular 100 mg/g Premix for Medicated Feeding Stuff 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.
The intake of medicated feed depends on the clinical condition of the animals. In order to obtain the correct dosage, the concentration of chlortetracycline has to be adjusted accordingly.
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 Granular 100 mg/g Premix for Medicated Feeding Stuff 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.
For incorporation into dry feed at the registered mill. A manufacturer who is approved to incorporate directly at any concentration, veterinary medicinal products or pre-mixtures containing such products must be responsible for mixing when incorporation is less than 2 kg per tonne for final feed.
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.
