1. Exclusive C-Hpg-8 standard strain for precise type-A coryza prevention: Prepared with inactivated Avibacterium paragallinarum type-A C-Hpg-8 standard strain with pure and targeted antigenicity. It accurately targets prevalent type-A infectious coryza strains in domestic chicken farms, effectively relieving typical symptoms such as facial swelling, runny nose and reduced egg production caused by coryza infection.
2. Graded immune cycle with ultra-long multi-stage protection: Equipped with differentiated immune duration for different chicken ages: 3 months for chickens under 42 days old and 6 months for chickens over 42 days old. The booster immunization procedure at 42 days and 110 days achieves an ultra-long 19-month protection cycle, greatly reducing repeated vaccination frequency.
3. Age-based differentiated dosage for higher immune adaptability: Scientifically differentiated dosage matches the physiological characteristics of chickens at different stages. The graded dosage ensures standard and balanced protective immunity for all age groups, avoiding insufficient protection or vaccine waste caused by unified dosage.
4. Mature full-inactivation technology with zero stress and zero virus diffusion risk: The fully inactivated vaccine has no live bacteria residue or strain reversion risk with ultra-high safety. No adverse reactions such as depression and reduced feed intake occur after vaccination, and it does not affect chicken growth and egg production performance.
5. Uniform emulsion formulation with stable absorption and durable efficacy: The uniform and delicate emulsion is stable without delamination or precipitation. The balanced antigen absorption stimulates stable high-level antibody production, ensuring uniform, durable and qualified herd immune effect.
6. Simple subcutaneous injection adapts to full breeding scenarios: Supports subcutaneous injection on the chest and nape with minimal trauma and fast recovery. The simple operation adapts to batch immunization of all-scale chicken farms with high practicability.
Q: What type of vaccine is this? What diseases does it prevent?
A: This is an inactivated infectious coryza (serotype A) vaccine, a non-prescription veterinary drug prepared with inactivated Avibacterium paragallinarum type-A strain, specially used to prevent chicken infectious coryza caused by type-A bacteria and avoid reduced egg production.
Q: What are the core advantages and protection characteristics of the vaccine?
A: Adopting exclusive type-A standard strain, the vaccine features precise targeted prevention, graded immune cycle (up to 19-month protection after booster), age-based differentiated dosage and high safety. With stable emulsion formulation and flexible specifications, it achieves efficient and long-term prevention of infectious coryza.
Q: What are the applicable chickens, vaccination method and standard dosage?
A: Applicable to healthy chickens of all breeds via subcutaneous injection on the chest or nape. The dosage is 0.25ml per chicken for birds under 42 days old and 0.5ml per chicken for birds over 42 days old to ensure qualified immune efficacy.
Q: What are the key operation requirements before vaccination?
A: Freezing is prohibited, and frozen deteriorated vaccines are forbidden for use. Warm the refrigerated vaccine to room temperature and shake fully before use. Disinfect injection sites and appliances strictly to ensure vaccination safety and efficacy.
