For use only under veterinary supervision.
1. Targeted epidemic strain for precise H9 subtype prevention: Adopts the prevalent H9N2 subtype Sy strain with high antigen matching degree for domestic mainstream epidemic strains. It efficiently targets and prevents H9 subtype avian influenza, solves typical breeding problems such as respiratory symptoms and reduced egg production, and meets the daily epidemic prevention needs of large-scale poultry farms.
2. Age-segmented precise immunization for full-stage chicken flocks: Scientific differentiated dosage and vaccination routes match the physiological characteristics of chickens at different stages. The low dosage for young chicks ensures low stress adaptation, while the dual vaccination routes for adult chickens improve operational flexibility, realizing comprehensive protection for flocks of all ages.
3. High-quality homogeneous emulsion with stable efficacy and easy absorption: The pure white homogeneous emulsion has stable physical and chemical properties without delamination or demulsification. The sustained-release antigen is easily absorbed after injection, stably stimulating antibody production and ensuring high uniformity and qualified rate of flock immunity.
4. Dual flexible vaccination routes adapt to large-scale breeding: Dual subcutaneous and intramuscular injection methods are available for adult chickens, which can be flexibly selected according to farm breeding modes and operation habits. It features simple operation and high efficiency, fully adapting to batch universal immunization of intensive poultry farms.
Q: What type of vaccine is this? What diseases does it prevent?
A: This is an inactivated avian influenza vaccine (H9 subtype, Sy strain), a non-prescription veterinary drug prepared with inactivated prevalent H9N2 subtype Sy strain. It is specially used to prevent avian influenza caused by H9 subtype virus and serves as the core basic vaccine for H9 influenza prevention in poultry farms.
Q: What are the core advantages and protection characteristics of the vaccine?
A: Adopting local prevalent Sy strain, the vaccine has high antigen matching and targeted prevention effect. With ultra-high virus titer, age-segmented precise dosage, 9-month ultra-long protection period, stable emulsion and flexible dual vaccination routes, it is highly suitable for daily epidemic prevention of large-scale poultry farms.
Q: What are the immune cycles of the vaccine?
A: The vaccine has stepped immune cycles. The immune protection period is 3 months for young chickens within 30 days old and up to 9 months for adult chickens over 30 days old. Supplementary immunization can be reasonably arranged according to flock age to maintain long-term high-efficiency antibody protection.
Q: What mandatory operation specifications should be followed before vaccination?
A: Take out the refrigerated vaccine and return it to room temperature before use to avoid low-temperature stimulation. Fully shake the vaccine before vaccination to ensure uniform emulsion and accurate dosage for each chicken, avoiding uneven immune protection caused by antigen delamination.
