Live vaccine for Infectious Bursal Disease in chickens (B87 strain). The B87 strain, recognized domestically as having the strongest antigen immunogenicity, was selected. Through dilution, cloning, and optimization techniques, the most immunogenic strain was screened out, offering extremely high immunity. 

· Purified seed antigen: Continuous centrifugation and ultrafiltration techniques remove unwanted proteins, making the antigen purer.

· Unique cultivation process: Ensures each dose contains ten times the standard antigen amount.

· Carefully selected SPF eggs for purity and safety: Using SPF eggs free from 24 pathogens.

· Special diluent: Various immune enhancers increase the vaccine’s effectiveness by 100%.

Usage and dosage: Can be administered via eye drop, orally, or by injection. Dilute as directed on the bottle label with saline, injection water, or cooled boiled water. Suitable for chicks of all breeds. Using it at 14–28 days is recommended depending on maternal antibody levels.
