Live freeze-dried vaccine, variant 1/96 strain. For the active immunization of chickens against Infectious Bronchitis
CEVAC IBIRD® is a live attenuated freeze-dried vaccine for the active immunization of chickens against variant strain of avian infectious bronchitis virus, containing strain 1/96.
CEVAC IBIRD® is recommended for the active immunization of broiler chickens, and future layer chickens in order to reduce the detrimental effect on the ciliary activity 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 is 3 weeks after one administration of the vaccine. Duration of immunity is 6 weeks after the first vaccination.
- Store vaccine between +2°C and +8°C or 35°F and 45°F
- Protect from light
1000 and 5000 dose vials
20 x 1000 dose vials / box
20 x 2500 dose vials / box
ADMINISTRATION AND DOSAGE
One dose of the vaccine should be administered by nebulisation use with coarse spray from 1 day of age. Older chickens can also be vaccinated by coarse spray.
Nebulisation method: 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 will vary according to the age of the chickens being vaccinated and the management system, but at least 250 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 a coarse spray providing droplet sizes in a range of 137-153 µm. The nebulisation use via coarse spray application 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.
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 re-vaccinated every 3 weeks. However, do not use in birds in lay and within 4 weeks before the onset of the laying period. 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.
