Abstract
The aim of study is provide basic data about the histological features of the liver of local Iraqi ducks and to study the glycogen content in the cytoplasm of the hepatocyte. The anatomical examination showed that liver laid cranial part of the abdominal cavity caudally and ventrally to the heart and associated to the gizzard. The liver of Mallard is divided into two undivided lobes right and left lobes (the right lobe is larger than left lobe). Histological examination revealed that the liver consist of several lobules separated from each other by thin trabeculae of connective tissue extend from delicate capsule that enclosed the liver. The basic unit of the parenchyma of liver is hepatocyte which arranged in plates or cords like that radiated around the central vein and between these cords there is sinusoids lined by alayer of fenestrated endothelial cells and Kupffer's cells. In the boundary of each lobule showed portal area which consist of hepatic artery; hepatic vein and bile duct lining by cuboidal cells. The histochemical study showed formed differ size of glycogen granules in cytoplasm of hepatocytes and in some speciment the glycogen large granules arranged around the central vein because the bird in starvation period .the liver of Mallard generally is closely similar to the liver of another avian birds and vertebrates
