AviPro AE

For administration via drinking water.

One vaccine dose per animal aged 14 weeks and older.

All animals of the population must be vaccinated.

The vaccine should be dissolved in the amount of drinking water consumed by the animals within 2 hours. The vaccine must be administered to the drinkers immediately after dissolution so that it is consumed by the animals within 2 hours at most after dilution.

To ensure the vaccine is consumed quickly, drinking water should be withheld from the animals for 1 -2 hours prior to vaccination. It must be ensured that all animals have adequate access to the vaccine suspension, but not have access to normal drinking water until the vaccine has been consumed.

Method of administration

Administration via drinking water

- Determine the required number of vaccine doses and the quantity of water (see below).

- Use the total contents of the vaccine bottles per one chicken house or drinker systems.

- All equipment used for vaccination (lines, hoses, drinkers etc.) should be thoroughly cleaned and must be free from residues of cleaning agents and disinfectants.

- Use only cool, clean, and fresh water, preferably free of chlorine and metal ions. Skimmed milk powder (2 - 4 g/litre water) or skimmed milk (20 - 40 ml/litre water) can improve the quality of the drinking water and prolong the activity of the vaccine; however, this supplement should be added to the water 10 minutes before adding the vaccine.

- Open the vaccine bottle under water and dilute its contents. Ensure that any remaining vaccine is completely emptied by rinsing the bottle and rubber stopper with water.

- Lines filled with water must be emptied before administering the vaccine suspension.

Add the diluted vaccine suspension to cold, fresh water such that, as a rule of thumb, 1,000 vaccine doses are dissolved in one litre of water per age in days for 1,000 chickens, e. g. 10 litres would be required for 1,000 chickens aged 10 days old.

Under hot climatic conditions and for heavy breeds, this amount may be increased to a maximum of 40 litres per 1,000 animals. In case of doubt, the daily water consumption should be determined before vaccination.

To reduce the risk of infection before the onset of immunity, the litter should be removed, and the chicken house cleaned between treatment cycles in the breeding unit.
