The present study was conducted on Ghungroo pig to investigate gross anatomical and histomorphological structure with ramification of portal vein and hepatic artery in liver. For the present investigation, ten livers were collected from adult, apparently healthy, freshly slaughtered Ghungroo pigs. Immediately after collection, gross anatomical observation was done. Out of ten livers, five were used for identification of portal vein and hepatic artery by RTV Silicone cast method and another five for the histological preparation. Histomorphological study was done by H &E, PAS and Masson’s Trichrome staining method. From the gross observation, it was found that the liver of pig was situated within the intra-thoracic part of the abdominal cavity. A small caudate lobe was found along with the four principal lobes. In the present study, it was revealed that hepatic artery before entering into the porta divided into right and left major branches which supplied to the lobes of liver. The portal vein entered the hilus of the liver between the hepatic artery dorsally and bile duct ventrally. Histological section of pig liver revealed that the outer most surface of parenchyma was covered with a fibrous capsule. The most predominate fibre of the capsule was collagen. The liver lobules were polyhedral to hexagonal in shape. The lobule was composed of hexagonal hepatic tissue measuring on an average 1.89mm in length and approximately 1.23mm in short diameter.
