The present experiment was conducted to investigate the relationship between immune-related parameters and reproductive traits in Fayoumi cocks. Three lines low; high and control were used to evaluate the association between immune responses, selected blood hormones, semen quality traits, and morphological measurements (comb and wattle growth). Antibody titers against NDV, H9, and H5 were not significantly affected by line. Plasma testosterone concentrations were significantly higher in the high and control lines compared with the low line. The plasma concentrations of T3 and T4 (ng/ml) were significantly higher in the low line compared with the high line, while no significant differences were observed between the control line and either the low or high lines. The T3/T4 ratio was not significantly affected. The greatest semen volume was observed in the low line compared with the high line. The control line did not differ from the high line, but it was significantly higher (P ≤ 0.05) than the low line. Similarly, sperm motility was significantly greater in the low line, followed by the control line, which did not differ from the high line. Comb width (cm), wattle width (cm), and wattle length (cm) were not significantly influenced by line. However, comb length (cm) was significantly improved in the control line, followed by the low and high lines. These findings suggest that careful selection of poultry breeds, suited to rearing conditions, production systems, and breeding objectives, along with balanced selection programs, is essential to maximize immune competence and reproductive efficiency.
