  1. Vaccine-specific antibody titers in sera were measured by IHA test (NDV) or ELISA tests, either direct (IBV, IBDV, MPV) or competitive (CIAV), at 8, 12, and 16 weeks of age
  2. aValues are least square means of antibody titers (± SE)
  3. bWald Chi-square test was significant at p < 0.05*; p < 0.01**; p < 0.001***
