Fig. 3From: Decreased eggshell strength caused by impairment of uterine calcium transport coincide with higher bone minerals and quality in aged laying hensDifferences in bone histomorphometry of the hens laying eggs with different eggshell breaking strength. The insets (E–H) are the zoomed-in images of the black boxes in A–D. (A, B, E, F) in the humerus; (C, D, G, H) in the femur; (A, E, C, G) in the HBS; (B, F, D, H) in the LBS. Black arrows, cortical bones; red arrows, trabecular bones. HBS, high eggshell breaking strength group; LBS, low eggshell breaking strength groupBack to article page
