Study on Microstructure and Mechanical Properties of Cage-Free and Caged Chicken Compact Bones

Abstract

The microstructure,composition and mechanical properties of cage-free and caged chicken's humeral compact bones were systematically analyzed from the perspective of material science.The bone microstructure was observed by the scanning electron microscopy;the energy dispersive spectrometer analysis,X-ray diffraction(XRD) tests and ashes calcined experiments were used to discuss the close relationship between organic and inorganic components in chicken's humeral compact bones;mechanics of materials testing machine and microhardness tester were used for measuring their mechanical properties.It is concluded that there are differences among cage-free and caged chicken's humeral compact bones in microstructure,composition and mechanical properties,which leads to the hardness and bending strength of cage-free chicken's humeral compact bones are better than those of caged chicken bones.
