CEVAC IBird Lyophilisate for Oculonasal Suspension/Use in Drinking Water for Chickens

chickens can also be vaccinated by spraying.
The vaccine should preferably be dissolved in distilled water or alternatively in cool, clean
chlorine free water. The appropriate number of vials should be opened under water. The
volume of water for reconstitution should be sufficient to ensure an even distribution when
sprayed onto the chickens. This will vary according to the age of the chickens being
vaccinated and the management system, but at least 200 ml of water per 1000 doses is
suggested. The vaccine suspension should be spread evenly over the correct number of
chickens, at a distance of 30-40 cm using droplet sizes in a range of 100-200 µm (coarse
spray). Spraying is preferable when the chickens are sitting together in dim light. The
spray apparatus should be free from sediments and corrosion traces or disinfectants.
For effective vaccine distribution, make sure that birds are closely confined together during
spraying.
Depending on housing conditions, ventilation should be switched off during and after
vaccination in order to avoid turbulences.
In drinking water use for future layer chickens
One dose of the vaccine should be administered by drinking water from 10 days of age. In
order to maintain immunity, chickens may be revaccinated every 3 weeks. No studies were
done to show protection during the laying period.
The vaccine should be dissolved in the drinking water. The amount of water should be
calculated based on the average water consumption of the flock in the previous 4 days
before vaccination. Calculate the amount of water needed, so that the vaccine is
consumed within 2 hours. This amount should be approximately 30% of the daily intake.
Medication, disinfectants and chlorine must be removed from the drinking water 48 hours
before vaccination.
Water should be withheld prior to vaccination to make the chickens thirsty. The period for
water withdrawal is dependent on the climate. Water withholding should be kept as short
as possible with a minimum of 30 minutes.
The vials should be opened under water. Use cool, clean water to dissolve the vaccine.
For administration of the vaccine, as a general rule, dissolve 1000 doses in one litre per
age in days up to a maximum volume of 20 litres per 1000 doses, or in hot weather, the
quantity of water may be increased up to 40 litres per 1000 doses.
Appearance of the reconstituted product: From slightly opalescent to colourless liquid.
