摘要： [目的]对比两种成分不同的奶粉对大鼠的生长状况和骨骼健康的影响。[方法]试验使用了21 只4 周龄SD雄性大鼠,随机分为对照组、奶粉组,奶粉组包括合生元儿童成长奶粉（金盖）（简称“金盖组”）和合生元儿童成长奶粉（蓝盖）（简称“蓝盖组”）,用对应饲料进行为期8 周的喂养,探究奶粉添加对大鼠体重、骨密度、骨强度、血清钙及机体免疫的影响。[结果]奶粉组大鼠的摄食量减少,体重维持在正常水平,与对照组无显著差异;两种奶粉均可显著提高大鼠的骨强度,其中金盖组的效果要高于蓝盖组;两种奶粉对大鼠骨皮质骨密度和骨小梁骨密度的增强效果不明显;两种奶粉均可增加大鼠的骨小梁厚度并降低骨小梁分离度,显示出对大鼠骨骼有良好的骨代谢调节能力;金盖组因含有低聚半乳糖（GOS）可帮助促进钙的吸收,血清钙含量比蓝盖组要高;奶粉组大鼠的IgM值相比对照组均有显著提高,而蓝盖组奶粉展现出更强的调节效果,可能与其含有的DHA有关。[结论]两款奶粉在增强骨强度,调节骨代谢及提高机体免疫力上具有良好的效果。

Abstract: [Objective] This study compared the effects of two different ingredients of milk powder on the growth status and bone health of rats. [Method] Twenty-one 4-week-old SD male rats were randomly divided into control group and milk powder group. The milk powder group included Biostime Children's Growth milk powder （Golden）（hereinafter referred to as Golden Group） and Biostime Children's Growth Milk powder （Blue）（hereinafter referred to as Blue group）,and the corresponding diets were fed for 8 weeks. To explore the effects of milk powder supplementation on body weight,bone density,bone strength,serum calcium and immunity in rats.[Result] The food intake of the rats in the milk powder group was reduced,and the body weight was maintained at the normal level,which had no significant difference with the control group. Both kinds of milk powder can significantly improve the bone strength of rats,and the effect of Golden group is higher than Blue group. The effects of two kinds of milk powder on cortical bone mineral density and trabecular bone mineral density of rats were not obvious;Both kinds of milk powder can increase the thickness of bone trabecular and reduce the degree of bone trabecular separation,which shows that the bone metabolism of rats has a good regulation ability. The content of serum calcium in Golden group was higher than that Blue group because GOS could promote calcium absorption. Compared with the control group,IgM values of the milk powder group were significantly increased, and the milk powder of the Blue group showed a stronger regulatory effect,which may be related to the DHA content.[Conclusion] The two kinds of milk powder have good effects on enhancing bone strength, regulating bone metabolism and improving body immunity.

Key words: Biostime children growth milk powder, bone strength, bone metabolism, body immunity
