Abstract: The present study evaluated the more precise and detailed information on the structure of hepatic artery and its branches diameter in sheep (Ovis aries). The liver samples along with coeliac artery were collected from twenty two apparently healthy sheep irrespective of sex from local slaughter houses and Acrylic cast preparations were made. The morphometry of the hepatic artery in terms of length and diameter were recorded by using digital calipers. The observed mean length and external diameters of CHA and PHA in these cast preparations were 30.4 ± 2.2 mm, 5.5 ± 0.5 mm and 2.33 ± 0.07 mm, 1.94 ± 0.02 mm respectively. The mean external diameters of RHA and its branches RSILA,RCILA, RInfILA, CPA and CA were 1.39 ± 0.02 mm, 0.81 ± 0.08 mm, 0.6 ± 0.08 mm, 0.51 ± 0.09 mm, 0.61 ± 0.15 mm and 0.96 ± 0.05 mm respectively. The LHA gave branches to papillary process of caudate lobe and then sub divided into LMB and LLB. LMB gave rise to LSILA and LIILA. LLB gave rise to QLA and LInfILA. The LHA, LMB and LLB mean external diameters were 1.64 ± 0.01 mm, 1.00 ± 0.07 mm and 1.16 ± 0.07 mm respectively while LSILA, LIILA, QLA and LInfILA mean diameters were 0.82
