Effect on BMD (mean ± SD, n = 10). BMD was measured using dual-energy X-ray absorptiometry. Proximal, proximal end; middle, middle segment; distal, distal end. A, sham operation; B, OVX model control; C1, OVX rats diet with BCAP of 0.04 g·d⁻¹; C2, OVX rats diet with BCAP of 0.20 g·d⁻¹; C3, OVX rats diet with BCAP of 0.40 g·d⁻¹. Values followed by different single letters are significantly different (P < 0.05).
