Cevac IBD 2512 L
Active substance
ATC code
Species
Chickens (broilers)
Indications
For the active immunization of broiler chickens from 10 days of age with maternallyderived antibodies against avian infectious bursal disease (IBD, Gumboro disease), to reduce mortality, clinical symptoms, weight loss and acute lesions in bursa of Fabricius, caused by very virulent infectious bursal disease virus.
Onset of immunity: 14 days post-vaccination.
Duration of immunity: 27 days post-vaccination.
Dose to be administered and administration route
In drinking water use.
Dosage: 1 dose / chicken.
For oral administration, via reconstitution in drinking water.
For vaccination of broiler chickens from a minimum of 10 days of age to approximately 18 days of age, depending on the level of maternally derived antibodies. The optimal timing of vaccination should be determined on the basis of virus neutralisation (VN) titres measured in 1- to 7-day-old chickens. The flock to be vaccinated should have a geometric mean VN titre of <1:450 at vaccination. To estimate MDA level of the flock to be vaccinated: 20, preferably 1-day-old chicks (maximum 7 day old) originating from the same breeding flock should be sampled to measure their serological status to IBD virus by VN. From the results of this sampling and based on the 3 days half-life-time for the IBD virus MDA, the most suitable time for vaccination can be determined.
Preparation and administration of the vaccine:
The number of vaccine doses should be dissolved in the amount of drinking water calculated upon water consumption of the birds to be immunized.
Age | 10–12 days | 14–18 days |
minimal amount of water for 1000 vaccine doses(for treatment of 1000 birds) | 10 litres | 15 litres |
Number of doses should be rounded up for smaller flocks and dissolved accordingly (i.e. dissolve 20,000 doses for the treatment of 19,450 birds).
Drinking water must not contain disinfectants for 48 hours prior to and for 24 hours after vaccination. Also chlorination of drinking water should be avoided during this period. Instruments used for preparation and administration of the vaccine must be free of residues of disinfectants.
Drinkers should be cleaned thoroughly before vaccination. Do not apply disinfectants for cleaning of the watering system for vaccination.
Drinking water should be withdrawn from birds for 2 to 4 hours prior to vaccination, depending on their age and the temperature of the house.
To preserve virus activity, it is advised to dissolve 2.5 g skimmed milk powder per litre of calculated drinking water, prior to dissolving the vaccine.
Open the vaccine vial under water and rinse it thoroughly after dissolution. Stir to dissolve the vaccine, distribute it to watering system proportionally and make it available to the chickens. It is advised to increase the number of drinkers during vaccination. To ensure that all birds have access to the vaccinated water, it is advised to move birds around the drinkers in the first few minutes of vaccination. The birds can be supplied with fresh drinking water only after the medicated water is consumed entirely.
The vaccine should be administered to birds immediately after reconstitution.
Administer the vaccine during the coolest part of the day.
Protect reconstituted vaccine from direct sunshine.
Protect birds to be vaccinated from stress conditions.
Adverse reactions
Data from safety studies involving administration of a single dose to the target species (10 day old chickens with MDA to IBD virus) are not available. Refer to section 4.10.
