Chicken Newcastle Disease, Infectious Bronchitis, Egg Drop Syndrome, and Avian Influenza (H9 subtype) Quadrivalent Inactivated Vaccine (LaSota strain, M41 strain, HS25 strain, HZ strain). HS25 strain is selected for Egg Drop Syndrome, effectively preventing the syndrome, with good immunogenicity after inactivation and high antibody production; the H9 subtype avian influenza HZ strain is preferred, providing effective protection against currently circulating strains. 

·       Carefully selected strains, high cross-protection rate: part of the Infectious Bronchitis provides excellent cross-protection against respiratory and kidney types

·       Antigen purification: ultrafiltration and concentration process, highly removes urate, lipopolysaccharides, and miscellaneous proteins from the allantoic fluid

·       Imported adjuvant, better absorption: viscosity index 20-40 cP (national standard 200 cP)

·       Advanced process, low immune stress: uses low-temperature emulsification and advanced inactivation process, small amount of formaldehyde inactivator

Dosage and administration: subcutaneous injection in the neck. Give 0.5ml per bird at 2-3 weeks before laying for layers and breeders.

Specification and packaging: 250ml/bottle
