用刚断乳小鼠,对强化牛奶粉(主要添加牛磺酸、乳酮糖、维生素A、D、C和微量元素Fe、Zn)进行了强化效果的研究。结果表明:实验组小鼠体重增长和Hb含量都稍高于对照组;骰骨钙含量、脑含氮量和蛋白质含量均明显高于对照组(P<0.001)。水迷宫试验呈现实验组小鼠的总潜伏期明显缩短(P<0.05)、错误次数显著减少(P<0.05)及全程时间缩短而无误率高的趋势。提示:本强化牛奶粉在促进动物生长发育,提高Hb含量,增加钙的吸收利用和脑发育上有良好作用;对小鼠学习、记忆能力也有增强的趋势。
Fortified milk powder (mainly taurine, lactose, vitamin A, D, C and trace elements Fe, Zn) was fortified with fresh-weaned mice. The results showed that body weight gain and Hb content in the experimental group were slightly higher than those in the control group. Calcium content, brain nitrogen content and protein content in the experimental group were significantly higher than those in the control group (P <0.001). The water maze test showed that the mice in experimental group had a significantly shorter total latency (P <0.05), fewer errors (P <0.05) and shorter overall time with higher error-free rate. Tip: The fortified milk powder in promoting animal growth and development, increase Hb content, increase calcium absorption and utilization and brain development has a good effect on mice learning, memory ability also increased.
