The present study emphasizes the importance of in Ovo feeding strategies, particularly the supplementation of fertilized eggs with amino acids such as L-arginine to enhance the Bursa of Fabricius development. Targeted nutritional interventions during embryogenesis offer a promising approach to improving the overall health, productivity, and market value of poultry. The experiment was done in the college of agriculture - University of Sulaimani to study the effects of arginine on the bursal tissue of commercial and local Kurdish chickens. One hundred fertile eggs involved from the Ross-308 broiler breeder strain and one hundred fertile eggs from a local breed. The in ova inoculation treated included a control group without inoculation and three groups inoculation with 1%, 2%, and 3% Arginine solutions. The inoculations were carried out twice, on the 14th and 18th days of incubation. Four chicks at one-day age from each Treated group were euthanized, and their bursa of Fabricius was preserved for histological slide preparation. The study found that bursal follicular proliferation in Kurdish breeds showed significant improvements in lymphoid follicles and number compared to commercial breeds. The scoring system for bursal follicular proliferation was higher in the G4 (3% Arginine) Treated group. However, bursal sections from Fabricius bursa showed significant aggravation in follicle number, with G3 and G4 Treated groups scoring higher. Eggs inoculated with arginine showed significant follicular growth in both breeds.
