The results showed that the titer of avian influenza antibody increased gradually after immunization with Avian Influenza Specific Immune Probiotic and avian influenza vaccine, and reached a peak after 1 month, and then gradually decreased. Compared with avian influenza vaccine, Avian Influenza Specific Immune Probiotic antibody titer of immune attenuation more slowly.
Avian Influenza Specific Immune Probiotic VS avian influenza vaccine (H9 subtype)
Measuring with chicken at the age of 14 days, noted the H9 antibody titer;
H9 antibody was injected intramuscularly at the age of 15 days;
Used Avian Influenza Specific Immune Probiotic at the age of 16 days.

The results showed:
There were maternal antibodies in egg chickens, and decreased with age.The antibody of Avian Influenza Specific Immune Probiotic AND H9 vaccines both increased, but Avian Influenza Specific Immune Probiotic much faster.
Avian Influenza Specific Immune Probiotic combined with H9 vaccine, the effect was significantly better than H9 vaccine group.

The antibody titers of H5 and H9 in broiler chickens were increased gradually after vaccination with H5 + H9 bivalent vaccine.
The antibody titers of H5 and H9 in broiler chickens were keeping above 51og2 from the 6th weeks. Compared with using of double-seedling only, more immune protection.
