NDV-specific antibody and neutralizing antibody induced by NDV vaccines. Broilers (n = 12/group) were s.c. or i.m. immunized with NDV Ag in saline or emulsified in E515-D, Marcol 52, or #10 white oil. Birds injected with saline solution alone served as a control. Blood samples were collected at 6 wk post immunization for analysis of NDV-specific antibody by ELISA (A, B) and neutralizing antibody titers (C, D). Data are represented as mean ± SD. Bars with different letters are statistically different (P < 0.05). Abbreviations: i.m., intramuscularly; NDV, Newcastle disease virus; s.c., subcutaneously.
