Abstract: The present study was carried out on healthy ten adult sheep aged above one year and body weight ranging from 25-30 kgs presented to Department of Veterinary Surgery and Radiology, NTR College of Veterinary Science, Gannavaram for the study of normal thoracic radiographic anatomy. The mean values of tracheal angle to the spine, thoracic inlet diameter, tracheal diameter, thoracic width, thoracic depth, cardiac width, cardiosternal contact and height of T₄ were 21.66±0.39⁰, 9.63±0.05, 1.52±0.03, 18.36±0.23, 19.21±0.21, 9.08±0.13, 5.45±0.5 and 1.4±0.01 in cm respectively. The mean values of Cranial mediastinal-cardiac angle, Sterno-costal angle, Spino-phrenic angle, Caval-cardiac angle, Caval-phrenic angle and tracheal angle were 87.54±0.58⁰, 130.3±0.58⁰, 41.2±0.37⁰, 41.2±0.37⁰, 40.09±0.46⁰ and 21.66±0.39⁰. The mean values of VHS measured on left lateral and right lateral views was 9.52±0.06 and 9.41±0.07 respectively.
