【COMPOSITION AND CONTENT】
Each bird dose of the vaccine contains live cloned Newcastle Disease Virus Strain I (CS2 Strain) at no less than 10⁵ ELD₅₀.
【CHARACTER】
Light yellow spongy loose mass, easily detached from the bottle wall and rapidly soluble after adding diluent.
【INDICATIONS】
For the prevention of Newcastle disease in chickens previously vaccinated with low-virulence of live Newcastle disease vaccine. The immune duration lasts 1 year.
【DOSAGE AND ADMINISTRATION】
Dilute the vaccine with sterile normal saline or other suitable diluents according to the dose specified on the vial label. Administer 1 mL per bird via subcutaneous or chest intramuscular injection.
【PRESENTATION】
500 doses/vial, 1000 doses/vial,
【ADVERSE REACTION】
Purebred chickens may show relatively strong stress reactions. Laying hens may experience reduced egg production or soft-shelled eggs within 2 weeks after vaccination.
【STORAGE AND SHELF LIFE】
. Store at -15℃ or below -15℃. Shelf life: 24 months from the date of manufacture.
For use only under veterinary supervision.
1. Classic I-series cloned CS2 strain for professional booster immunization: Adopts the stable and high-antigenicity I-series cloned CS2 medium-virulence strain. It is specially developed for flocks with completed basic immunization, serving as the core booster vaccine to remedy antibody attenuation, suppress wild virus infection and avoid recurrent Newcastle disease in the middle and late breeding stage.
2. 12-month ultra-long immune cycle reduces repeated immunization: The ultra-long 1-year protection cycle far exceeds that of conventional low-virulence vaccines. One standard booster vaccination realizes full-year protection, greatly reducing labor costs and repeated vaccination stress for large-scale poultry farms.
3. Professional injection vaccination ensures uniform and stable antibodies: Chest intramuscular or subcutaneous injection features accurate dosage and stable antigen absorption. It avoids the environmental interference of respiratory immunization, ensures highly uniform flock antibodies and controllable immune effect, and is suitable for standardized booster immunization of large-scale flocks.
4. High-quality freeze-dried formulation for accurate and uniform vaccination: The pale yellow loose sponge-like mass dissolves rapidly and completely without caking or impurities. The uniform medicinal liquid ensures standard antigen intake for each chicken and eliminates uneven immune protection.
5. Scene-oriented design avoids cross-infection risks: Equipped with standardized operation specifications for mixed breeding scenarios of adult chickens and chicks, it effectively prevents vaccine virus transmission and chick casualties, balancing immune efficacy and farm biosafety.
Q: What type of vaccine is this? What is its main function?
A: This is a live Newcastle disease vaccine (CS2 strain), a non-prescription veterinary drug with medium virulence. It is exclusively used for booster immunization of flocks that have completed basic immunization with low-virulence vaccines for long-term Newcastle disease prevention.
Q: What are the core advantages and protection characteristics of the vaccine?
A: The classic CS2 medium-virulence strain provides powerful booster immune efficacy and rapidly improves antibody levels. It features a 12-month ultra-long protection cycle, stable antibody performance via injection vaccination and a 24-month shelf life, perfectly suitable for long-term enhanced prevention in the middle and late breeding stage.
Q: What precautions should be taken for farms with mixed breeding of adult chickens and chicks?
A: Strict disinfection and partition isolation must be carried out during vaccination for mixed breeding farms to prevent vaccine virus transmission and avoid chick death caused by cross infection.
Q: Which dilution media are applicable for the vaccine?
A: Compatible with sterile normal saline and other suitable special sterile diluents to ensure stable virus activity and qualified immune efficacy.
