Study on walking gait characteristics were made from the videographs of six live adult animals of each species. The forelimbs of the buffalo were found to bear significantly (P < 0.05) more body weight (57.89 ± 0.82 %) than those of the ox (55.96 ± 1.05 % ). The cortical thickness, bone density and elastic modulus of the bones of the forelimbs, did not differ significantly (P < 0.05) from those of the hindlimbs of the animals of both the species within the same age groups. The pooled mean values of the cortical thickness,the bone density and the elastic modulus of the bones of the calves, were significantly (P < 0.05) lower (0.18 ± 0.001 cm; 2281.27 ± 14.21 - 2 kg/cm and 118.37 ± 0.11 kg/cm2, respectively) than those of the adult animals (0.54 ± 0.002 cm, 2510.54 ± 9.28 kg/cm2 and 166.33 ± 0.17 kg/cm2 , respectively). The ultimate compressive and tensile stresses, and ttie strength and stiffness economics, increased significantly with the advancement of the age. Most of the gross anatomical and the biomechanical characteristics of the bones and the muscles studied, increased significantly (P < 0.05) from the calfhood to the adulthood in both the species.enVETERINARY ANATOMYA STUDYThesis
