Abstract
A current study objective was to investigatethe effect of maternal immunization during the period of collecting eggs for hatching on maternal immunity transmitted to their chicks at two weeks of age. The total number of chicks was 180 used from thirty-two hens. Hens were divided into three segments according to antibody titer of SRBCs (high, medium, and low) segments. The resulting fertilized eggs were divided into two groups (Group < strong>1 and Group < strong>2) based on the period of egg collection after maternal SRBCs antigen injection. The obtained results were: 1.The transfer percentages for the three segments (high, medium, and low) were 2.88, 5.56, and 60.74%, respectively. Here we notice a clear inverse relationship between the level of maternal antibodies and the remaining percentage of immunity transmitted to the chicks at two weeks of age. Where, the transfer percentages for two separate groups (group < sub>1 and group < sub>2) were 1.48, and 12.65%, respectively. This means that the second group is higher than the first group in the transfer percentage of remaining maternal antibodies at two weeks old chicks. 2.There were significant differences between dams’ antibody titers to SRBCs antigen means, whether in the three segments (high, medium, and low) and, between the two groups. 3.There was a significant interaction between both segments (high, medium, and low) and groups (group < sub>1 and group < sub>2). In antibody titers to SRBCs antigen means of dams and antibody titers to SRBCs antigen transformed means in two-week chicks old of dams for two-week-old chicks, but there were no significant differences between segments (high, medium, and low) in antibody titers to SRBCs antigen transformed means in two-week chicks.
