The Importance of Vaccinating against IBV in Poultry
The Infectious Bronchitis Virus (IBV) poses a significant threat to the poultry industry due to its highly contagious nature and its capacity to cause acute infections in chickens.1
To combat IBV, vaccination stands as the key strategy. However, the global prevalence of both classical and variant IBVs, coupled with the limited efficacy of traditional Mass-type vaccines against multiple IBV variants, presents considerable challenges for effective control.3,4
These variants have been identified across various regions, such as: Latin America5, Africa6, Asia7, and Australia8. Understanding the genetic diversity of IBV has led to the classification of 32 lineages within 6 genotypes based on analysis of the S1 gene. While certain lineages like GI-1, GI-13, and GI-19 exhibit broad distribution, notably, the GI-23 lineage, initially confined to the Middle East, has now gained prominence and extends its presence to Europe, Asia, and Africa, indicating its expanding geographical influence over time.9
Product Details
Composition (Before Inactivation)
Strategically designed to tackle both classical and variant challenges, effectively expanding the umbrella of protection.
- Inactivated Avian Infectious Bronchitis Virus GI-1 [BV-EG/M41-ME01/2011] ≥ 7.0 log10 EID50
- Inactivated Avian Infectious Bronchitis Virus GI-13 [ME/IBV-VAR1/2017] ≥ 7.0 log10 EID50
- Inactivated Avian Infectious Bronchitis Virus GI-23 [Eg/1212B] ≥ 7.0 log10 EID50
Indications
For booster vaccination and protection of chickens against Avian Infectious Bronchitis Virus.
Vaccination Program
Birds can be vaccinated from 14 days of age onwards. For an optimal booster effect, the birds must be primed with live vaccines against Infectious Bronchitis Virus. The most suitable vaccination program shall be justified by a veterinary surgeon according to the health conditions of each farm and area.
Withdrawals
Zero days.
Dosage
The vaccine dose (0.5 mL/bird) should be administered subcutaneously in the lower part of the neck or intramuscularly into the chest muscles.
Administration
Proper administration of the vaccine is crucial for ensuring its efficacy. The vaccine should only be administered to healthy chickens that are not immunosuppressed. Before use, the vaccine should be shaken well to ensure proper mixing. Sterile injection equipment should be used to avoid contamination.
- Subcutaneous injection: applied in the lower part of the neck. The needle should be inserted just under the skin in a direction away from the head and in a straight line with the neck.
- Intramuscular injection: when applied in the breast muscles the needle must be inserted with a 45° angle to avoid intraperitoneal injection.
Birds can be vaccinated from 14 days of age onwards. For optimal booster effects, the birds should be primed with live IBV vaccines.
