Six vaccination programs against Newcastle disease were evaluated. The criteria of evaluation were hacmagglutination-inhibition (HI) test for humoral immunity, lymphocyte transformation (LT) test for cell-mediated immunity, cillary activity (CA) test for local tracheal immunity and challenge test for overall vaccinal protection. The vaccines used are Hitchner B1, LaSota and inactivated oil-adjuvant vaccines. The early vaccination with Hitchner B, vaccine gave a considerable immune response but not as high as later vaccination. While the use of inactivated oil-emulsion vaccine with living vaccines, specially if simultaneously used, afforded a solid immunity particularly if used at 5 day-old under our experimental conditions.
