The experimental study was carried out to evaluate the humoral and cell mediated immune response in Type I and Type II backyard chicken varieties with 25% Aseel inheritance. The humoral response was computed against sheep red blood cells (SRBCs) for haemagglutinin (HA) antibodytitre on 5 days post-immunization. It was expressed as log2 of the highest dilution which shows complete haemagglutination. The HA titers of Type I and Type II genetic groups were 8.17 ± 0.50 and 7.60 ± 0.48, respectively with males having higher titre over their counterpart females. The in vivo cell response to Phytohaemagglutinin-P (PHA-P) was quantified as Foot Index (FI) in mm where the respective Type I and Type II genetic group’s1.61 ± 0.09 and 1.60 ± 0.09 with significant sex effect i.e males exhibited significantly higher response than females. The result of present study suggests that the two genetic groups, Type I and Type II are equally competent and had better immune response to fight against infections.
