Abstract

The liver is a vital organ in animals, particularly in poultry, and having a detailed understanding of its anatomy and histology is important for veterinary and comparative anatomical studies. The present study aimed to examine the macroscopic and microscopic characteristics of the liver in healthy male Pekin ducks. Ten male ducks, aged 6-8 months and weighing 3.5-4 kg, were obtained from different areas of Baghdad, Iraq, to examine the anatomical size and internal structure of their livers. The size, color, lobes, and gallbladder position of the Pekin duck liver were assessed through macroscopic observation. Histological examination was performed to assess the capsule, hepatic tissue structure, sinusoids, hepatocytes, portal areas, and lymphocytic aggregates. The present results indicated that the Pekin ducks' livers were dark red to reddish-brown and located ventrally in the abdominal cavity. Pekin ducks' livers consisted of two lobes without any secondary lobulation. The right lobe measured 78 mm in length, 35 mm in width, and the left lobe measured 51 mm in length and 33 mm in width. The liver was surrounded by Glisson's capsule with thin septa. Hepatocytes were arranged in radial cords around the central vein, with sinusoids containing Kupffer cells. The portal area contained branches of the portal vein, hepatic artery, bile duct, and lymphatics. Lymphocytic aggregates were observed in hepatic cords and portal areas. The present findings provided baseline morphological and histological data on the Pekin duck liver, supporting future anatomical and veterinary investigations. © The Author(s) 2026.
