Source: VMD Summary of Product Characteristics (SPC). Last updated 26 Mar 2026.

For treatment and control of respiratory and systemic infections associated
with organisms sensitive to chlortetracycline.
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.
