Abstract

The Blue bull (Boselaphus tragocamelus) is regarded as one of the biggest antelopes in Asia and safeguarded beneath the IUCN since 2003 and under safeguard of ‘Schedule III’ of the Indian Wildlife Protection Act, 1972. This study focused on the detailed gross morphometrical study of mid thoracic ribs of Blue Bull (Boselaphus tragocamelus).

The present morphometrical study was carried out in six specimens of adult Blue bull (Boselaphus tragocamelus) of either sex. The measurements of various parameters of ribs were taken with the help of weighing machine, thread, scale and digital Vernier's calliper.

It was found that the average diameter of the head of the fourth rib was found to be 2.56±0.01 cm in adult Blue bull. Further, it was measured as 2.53±0.01 cm in females that was significantly less (P<0.05) than that of males, where it was found to be 2.59±0.01 cm. The average cranio-caudal diameter of the cranial articular facet of the head of 5th rib was found to be 0.97±0.01 cm in adult Blue bull. Further, it was measured as 0.95±0.02 cm in females that was significantly less (P<0.05) than that of males, where it was found to be 1.00±0.01 cm. The average diameter of the tubercle of sixth rib at the dorso-ventral aspect was found to be 1.66±0.01 cm in adult Blue bull. Further, it was measured as 1.64±0.02 cm in females that was significantly less (P<0.05) than that of males, where it was found to be 1.69±0.02 cm. Similarly, the average minimum length of the neck of sixth rib at the cranial aspect was found to be 0.68±0.01 cm in adult Blue bull. Further, it was measured as 0.65±0.02 cm in females that was significantly less (P<0.05) than that of males, where it was found to be 0.70±0.01 cm. The average diameter of vascular groove of seventh rib at the proximal aspect was found to be 0.56±0.01 cm in adult Blue bull. Further, it was measured as 0.52±0.01 cm in females that was significantly less (P<0.05) than that of males, where it was found to be 0.60±0.01 cm.
