骨矿物质与动物身体的性能和健康密切相关。矿物生物磷灰石(BaP)是骨组织的主要成分。本研究采用拉曼光谱和电感耦合等离子体发射光谱(ICP-OES)对猪股骨中BaP的矿物学变化进行了研究。在猪的两个生长阶段(生长期和育肥期)添加不同的低聚木糖(XOS)进行饲养。结果表明，XOS可以降低BaP矿物PO4In的碳酸盐取代度，提高矿物的结晶度。电感耦合等离子体光谱数据与拉曼光谱结果相一致，说明饲喂低聚半乳糖的猪骨BaP的溶解度较低。此外，XOS在生长期(65千克之前)的效果远好于育肥期(65千克之后)。此外，较高的XOS加入量(0.1~0.5 mg/kg)有利于提高骨BaP的结晶度。本研究为应用拉曼光谱和电感耦合等离子体光谱技术研究不同处理方式下猪骨中矿物质的细微变化提供了有益的参考。
Bone mineral is strongly correlated with performance and health of animal bodies. The mineral bioapatite (BAp) is the dominant component in bone tissue. This study investigated mineralogical changes of BAp in pig femur by Raman spectroscopy and inductively coupled plasma optical emission spectrometry (ICP‐OES). The pigs had been raised with various xylooligosaccharide (XOS) additions at two stages of growth (growing and fattening periods). The results show that XOS can decrease the degree of carbonate substitution for PO4in BAp mineral and improve the mineral's crystallinity. ICP data is consistent with the Raman results, that is the low solubility of bone BAp for pigs fed with XOS. Additionally, the effect of XOS is much better in the growing period (before 65 kg) than in the fattening period (after 65 kg). Moreover, the high addition of XOS (within the range of 0.1–0.5 g/kg) would be appropriate to improve the crystallinity of bone BAp. This study sheds light on applying Raman and ICP techniques to investigate the delicate changes of mineral in pig bones undergoing different managements.
