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

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.
