To carry out the studies animals of the Canchim and Nellore bovine breeds of precise and controlled origin were selected, all having the same biological and biomechanical processes from birth to slaughter that occurred before adulthood. Metatarsal bone samples were prepared and characterized by scanning electron microscopy and optical and energy dispersive spectroscopy. Subsequently, their microhardness, elastic modulus, and resistance to plastic deformation by nanoindentation were analyzed. Finally, the crystal structure of dry bone metatarsals was characterized by X-ray diffraction, obtaining grid, crystal size, and micro-formation by the Rietveld refinement method. The results showed that the bones of the two races showed differences not only visually, in the microscope images, but also statistically in the modulus of elasticity, crystallite size, and Knoop microhardness. However, they presented statistical similarities in hardnesses, calcium and phosphorus ratio, and microstructure (micro deformation and parameters of the network). From the results presented, it can be concluded that despite the breeds having the same breeding protocol, the bones presented some differences in their characterization, and, consequently, the manufacture of biomaterials from these bones must follow different protocols.  aCrystal structure  aHardness  aHydroxyapatite  aMicroarchitecture  aX ray diffractions1 aCAMARGO, I.
