Aivlosin is a range of products designed to be added to drinking water or food. There are specific products intended to protect against particular respiratory or other diseases. The range includes medication for chickens, pheasants and pigs.


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).


Indicated for treatment of respiratory disease associated with Mycoplasma gallisepticum in pheasants.

Dosage and administration

For use in drinking water.

The dosage 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. Select the correct pack size and number of sachets according to the amount of product required. For example, one sachet of 40 g is sufficient to treat a total of 1000 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 dosage the concentration of Aivlosin has to be adjusted accordingly.

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

The 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 1500 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.

No known incompatibilities.

Contra-indications, warnings, etc
