Cevac IBird
Active substance
ATC code
Species
Chickens
Indications
For the active immunisation of broiler and future layer chickens in order to reduce the detrimental effect on the ciliary activity and presence of virus in trachea resulting from the infection, which may be manifested in respiratory clinical signs. Protection was demonstrated by challenge with the 793/B strain, which is a representative strain of the 793/B group.
Onset of immunity: 3 weeks after one vaccination.
Duration of immunity: 6 weeks after one vaccination, except for future layers in which duration of immunity is 9 weeks after the first vaccination by spraying.
Dose to be administered and administration route
Oculonasal use for broiler and future layer chickens
One dose of the vaccine should be administered by spraying from 1 day of age.
Older chickens can also be vaccinated by spraing.
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.
Adverse reactions
Common (1 to 10 animals / 100 animals treated): | Tracheal rales* |
* Slight tracheal rales were observed after vaccination with the product, which may persist for at least 10 days
Reporting adverse events is important. It allows continuous safety monitoring of a veterinary medicinal product. Reports should be sent, preferably via a veterinarian, to either the marketing authorisation holder or the national competent authority via the national reporting system.
