Aivlosin 625 mg/g Granules for Use in Drinking Water for Pheasants


Aivlosin® 625 mg/g Granules for Use in Drinking Water for Pheasants is a white granular powder containing 625 mg/g tylvalosin (as tylvalosin tartrate).


Treatment of respiratory disease associated with Mycoplasma gallisepticum in pheasants.

Dosage and administration

For use in drinking water.

The dose is 25 mg tylvalosin per kg bodyweight per day in drinking water for 3 consecutive days.

Determine the combined bodyweight (in kg) of all the birds to be treated. For example, one sachet of 40 g is sufficient to treat a total of 1,000 birds with an average bodyweight of 1 kg; one sachet of 400 g is sufficient to treat a total of 10,000 birds with an average bodyweight of 1 kg. In order to achieve a correct dose, the preparation of a concentrated (stock) solution might be required (e.g. to treat a total of 500 kg total bird weight, only 50% of the prepared stock solution prepared from the 40 g sachet should be used).

The veterinary medicinal product should be added to a volume of water that the birds will consume in one day. The intake of medicated water depends on the clinical condition of the animals. In order to obtain the correct dose the concentration of Aivlosin has to be adjusted accordingly.

No other source of drinking water should be available during the medication period.

Mixing instructions

The veterinary medicinal product may be mixed directly into the drinking water system or first mixed as a stock solution into a smaller amount of water, which is then added into the drinking water system.

When mixing the product directly into the drinking water system, the contents of the sachet should be sprinkled onto the surface of the water and mixed thoroughly until a clear solution is produced (usually within 3 minutes).

When preparing a stock solution, the maximum concentration should be 40 g of product per 1,500 ml and it is necessary to mix the solution for 10 minutes. After this time, any remaining cloudiness will not affect efficacy of the product.

Only a sufficient amount of medicated drinking water should be prepared to cover the daily requirements.

Medicated drinking water should be replaced every 24 hours.


No signs of intolerance have been observed in poultry species at up to 150 mg tylvalosin per kg bodyweight per day for 5 days.

Contra-indications, warnings, etc

Withdrawal period

Meat and offal: 2 days.

Do not release pheasants for at least two days after the end of medication.

Not for use in birds producing or intended to produce eggs for human consumption. Do not use within 14 days of the start of the laying period.

Use during pregnancy, lactation or lay

The safety of the veterinary medicinal product has not been established during lay.

Special warnings for each target species

Treat as soon as possible after clinical signs suggestive of mycoplasmosis are observed.

Treat all the birds in the affected flock.

Special precautions for use in animals

Good management and hygiene practices should be introduced to reduce the risk of re-infection.

Use of the product should be based on susceptibility testing of the bacteria isolated from the animal. If this is not possible, therapy should be based on local (regional, farm level) epidemiological information about susceptibility of the target bacteria.

Use of the veterinary medicinal product deviating from the instructions may increase the risk of development and selection of resistant bacteria and decrease the effectiveness of treatment with other macrolides due to the potential for cross-resistance.

Special precautions to be taken by the person administering the veterinary medicinal product to animals

Tylvalosin has been shown to cause hypersensitivity (allergic) reactions in laboratory animals; therefore, people with known hypersensitivity to tylvalosin should avoid contact with this product.

When mixing the veterinary medicinal product and handling the medicated water, direct contact, with eyes, skin and mucous membranes should be avoided. Personal protective equipment consisting of impervious gloves and a half-mask respirator conforming to European Standard EN 149 or a non-disposable respirator conforming to European Standard EN 140, with a filter conforming to European Standard EN 143 should be worn when mixing the product. Wash contaminated skin.

In case of accidental ingestion, seek medical advice immediately and show the package leaflet or the label to the physician.
