| Abstract |
Antibody response to primary and secondary immunization with Newcastle disease virus (NDV) and sheep red blood cells (SRBC) antigen was studied in male of leghorn. White Baladi and their cross chicks. At 7 and 22 days of age, the chicks were vaccinated against NDV by Hitchner BI and lasota strain vaccine, respectively. at 35 and 56 days of age, chicks were injected with 0.2 ml of 10% SRBC suspension via brachial vein. To detect primary and secondary anti-NDV and SRBC antibody titer, blood samples were drown at 3,6,9 and 12 days post first and second immunization with each antigen. Correlation coefficients were calculated between primary and secondary antibody response. In general, leghorn chicks had significantly superior primary and secondary anti-NDV antibody titer over both white Baladi and cross chicks, but no significant differences were observed between antibody titer of white Baladi and cross chicks. On the other hand, no differences were observed in pooled means of primary antibody titer against SRBC between genotype. However, white Baladi chicks had significantly the highest secondary anti-SRBC antibody level as compared to leghorn or cross chicks. Cross chicks occupied second with significantly difference than leghorn chicks. The results of this experiment show that correlated response between primary and second response were not always observed.
