We were preferred bovine cortical bone to the others in xenobonegrafts for human and small animals, because those were not limited to supply and have sufficient size for bone transplantation. The strength (ST) and stiffness (SF) of cortical bone in bone grafts were very important. The strength and stiffness of cortical bone were much difference according to position of long bone in bovine limbs because which were biomechanical different to bear body weight. Therefore, we determinated by three bending point test methods the strength and stiffness of cortical bone which were collected in diaphysis of humerus, radius, femur and tibia of bovine. In the results, the strengths and stiffness among these were highest in radius by ST: 253.84$\pm$40.80 MPa, SF: 7.89$\pm$1.91 Gpa and lowest in humerus by ST: 185.69$\pm$28.54 MPa, SF: 6.21$\pm$1.22 Gpa.
