HI Antibody levels and the specific IgG levels induced by L. lactis HA1-Fc. A Antibody titers determined by HI assay after the chickens were vaccinated with PBS, L. lactis, L. lactis HA1, L. lactis HA1-Fc and inactivated H9N2 vaccine. B The antigen specific IgG titers of chickens after vaccination detected by indirect ELISA. The data were showed as means ± SD (n = 5). **P < 0.01 relative to PBS and L. lactis. ##P < 0.01 relative to L. lactis HA1
