Effect of rearing systems on bone geometric characteristics (A–H) and component (I-O) in the aged laying hens (95 weeks of age) (n = 6). (A) Bone weight, (B) Volume, (C) Density, (D) Length, (E) Midpoint perimeter, (F) Mean relative wall thickness, (G) Cortical cross-sectional area, (H) Mean cortical index, (I) Fat-free dry weight, (J) Ash, (K) Ash content, (L) Ca content in ash, (M) Total Ca per bone, (N) P content in ash, (O) Total P per bone. CCS, conventional caging system; AVS, aviary system. Data represent means with standard error. *p < 0.05.
