Online published on 1 August, 2019. Abstract The present study was carried out on the lumbar vertebrae of adult Blue bull (Boselaphus tragocamelus) of either sex. Biometrical observations on different parameters of lumbar vertebrae reflected significance (P<0.05) differences between the sexes of this species. It was confirmed that the average length of body gradually decreased from fourth to sixth lumbar vertebrae in the Blue bull. The average transverse diameter or width of vertebral canal and average vertical diameter or height of the vertebral canal was largest in the sixth lumbar vertebra. The average length of transverse process gradually increased from fourth to fifth lumbar vertebra and then it suddenly decreased in the sixth lumbar vertebra. The average height of the dorsal supraspinous process gradually decreased from fourth to sixth lumbar vertebrae and it was lowest in the sixth one. The data on the biometry of fourth, fifth and sixth lumbar vertebrae of Blue bull would develop a baseline that could be useful to the wild life Veterinarians in identification and solving vetero-legal cases.
