由已报道的配方试产的儿童食品中选择5种进行大鼠营养实验。结果表明,各组动物的体重增重、饲料效价、蛋白质功效比值、氮平衡、蛋白质真消化率、血清钙、动物脏体比值及病理解剖与镜检等指标均以强化赖氨酸的儿童营养面包的营养效应显著地优于其它各实验食品。由于阳性对照组各项指标均合乎规律地优于实验食品组,说明本实验结果可信。据此配方适当修改后,可进行人体营养效应观察。 Five kinds of children’s food products that have been reported in the trial have been selected for rat nutrition experiments. The results showed that weight gain, feed titer, protein efficacy ratio, nitrogen balance, protein true digestibility, serum calcium, animal body ratio, and pathological anatomy and microscopic examination were all used to strengthen lysine in all groups of animals. Nutritional effect of nutritional bread is significantly better than other experimental foods. Since the indicators of the positive control group were all more regular than the experimental food group, the result of the experiment was credible. According to this formula, the nutrition effect can be observed after proper modification.
