Infectious Coryza Trivalent Vaccine Description
This Inactivated Infectious Coryza Vaccine (Serotype A, B, C) is specifically developed to protect chickens against infectious coryza caused by Avibacterium paragallinarum, one of the most common bacterial respiratory diseases in poultry production.
The vaccine contains three major serotypes (A, B, and C), providing broad-spectrum protection against field strains and reducing the risk of production losses caused by decreased egg production, poor growth performance, and increased mortality.
Formulated as a stable oil-emulsion vaccine, it ensures strong immune response and extended protection up to 9 months after booster vaccination, making it especially suitable for layers and breeder flocks.
This product is ideal for integration into standard poultry vaccination programs, particularly in regions with a high prevalence of infectious coryza.
