[Variations in mineralization of cortical and medullary bone in laying hens during and after hypocalcemic diet].
Compact and medullary bone of femur, tibia and humerus during a period of calcium depletion and repletion have been studied by microradiographic and microdurimetric method. From our preliminary results it appears that the degree of mineralization varies only in medullary bone, where the existing trabeculaea are eroded and substituted by others that don't complete mineralization. The cortical bone is deeply eroded during the diet and slowly reconstructed during the period of calcium repletion.
