Introduction: As the largest gland in the body, the liver plays a role in a wide range of functions including fat, carbohydrate, protein, vitamin and mineral metabolism, waste removal, and detoxification. Objective: The present study was carried out with the aim of comparing the histology, histomorphometry and histochemistry of the livers from male turkey and local cock in Urmia city. Methods: In this study, 5 male turkeys and 5 healthy adult local cocks were obtained from Urmia city. After halal slaughter, fixation of animal liver samples and tissue passage, 5-7 micron sections were subjected to H&E, Trichrome-Masson, toluidine blue, PAS and Sudan Black stainings for histological, histomorphometric and histochemical studies. Results: The results of the histological and histochemical examinations were almost similar in both species of birds, but in the histomorphometric study, the average thickness of the bilayer plates of hepatocytes and the number of Kupffer cells in cocks were significantly higher than those in male turkeys, while the average number of hepatocytes, portal areas, and central veins in turkeys were significantly greater (p<0.05). There was no significant difference in the average number of mast cells in the liver tissue between the two bird species. Moreover, a large amount of carbohydrate accumulation and fat granules were observed in the cytoplasm of hepatocytes from the cocks. Conclusion: In general, the greatest differences in the liver tissue of male turkeys with that of the cocks are related to histomorphometric parameters which had significant differences in all studied parameters except the number of mast cells (p<0.05).
