Abstract

The aim followed in the present study was an evaluation of the adaptive immune traits (cellular and humoral) of both males and females in Iranian commercial vs Azarbayijan native fowls. Information obtained from cellular and humoral responses of 49 birds of Arian broiler line. 79 Azarbayijan native birds were made used of. Total antibody titration, Immunoglobulin Y titration (IgY), and Immunoglobulin M titration (IgM) were determined with in the birds^,22 and 50 weeks of age following a challenging of the birds with sheep red blood cells. Moreover, the cellular immune responses of the birds were determined following a challenging of the birds with phytohemaglutinin. For the 22 weeks of age birds, the total antibody and IgY titres were significantly higher in the native strain than in those of the Arian strain. As for Arian strain, sexual dimorphism was observed within 22 and 50 weeks of age birds for total antibody and IgY titres, while, for humoral immune responses no significant difference was observed for native strains. Unlike humoral immunity, in native strains^, sexual dimorphism was found for cellular immunity. As for Arian strain there were no significant differences observed for cellular immune response between males and females.
