Calves
The product is indicated in the treatment of respiratory disease in calves caused by
Pasteurella spp., sensitive to chlortetracycline.

For oral administration after incorporation in a feeding stuff by a facility licensed to
medicate feed.
Administration:
The recommended therapeutic dose is 20 mg per kg bodyweight daily i.e. 20 grams
of Chloromed 150 mg/g Premix per 150 kg bodyweight.
For the preparation of the medicated feed the body weight of the animals to be
treated and their actual intake of feed should be taken into account. To ensure the
correct dosage and to avoid under-dosing, the body weight should be determined as
accurately as possible. The required dose should be measured by suitably calibrated
weighing equipment. During the treatment period, only feed medicated with the
product should be supplied. To provide the required amount of active substance per
kg medicated feed the premix has to be incorporated into the feed according to the
following formula:
feedofkgChloromed/mg...
)(kg/animalintakefeeddaily Average
treatedbe toanimalsof(kg)bwAveragebw/day x kgChloromed/mg...

Treatment should be continued for a period of seven days. If animals don’t recover
within 3 days after oral medication, diagnosis should be reconsidered and treatment
should be changed, if necessary.

The uptake of medicated feed depends on the clinical condition of the animals. In
order to achieve the correct dosage the chlortetracycline inclusion rate in feed should
be adjusted for feed intake.
Pelleting should not be conducted at temperatures in excess of 70°C.

Do not use in calves over 6 months of age and dairy cows.
Do not use in animals with known hypersensitivity to tetracycline.
Do not use in animals with severe liver and renal disorders.

Chlortetracycline toxicity is low. If digestive disturbances do occur, treatment should
be discontinued.
On rare occasions the following adverse reactions may occur: allergic reactions and
photosensitivity; gastrointestinal disorders; disorders of the liver and the kidneys. If
suspected adverse reactions occur, treatment should be discontinued.
Due to the possible incorporation of chlortetracycline, treatment of pregnant and
newborn animals can lead to dysfunctional development of the skeleton and teeth in
foetal and growing animals.

The uptake of oral medication by animals can be altered as a consequence of illness.
In case of insufficient uptake of feed, animals should be treated parenterally.
