摘要:

目的:6种国产品牌(3个为国产奶源,3个为进口奶源)的婴儿配方奶粉和6种外国品牌(3个为内地销售,3个为香港销售)的婴儿配方奶粉分别喂养实验动物,研究比较中外婴儿配方奶粉在实验动物上引起的营养生物效应的差异。方法:采用刚断乳SD大鼠,在连续30d左右的喂养实验后,检测实验动物的安全性和营养学指标。结果:12种受试品牌奶粉在实验动物体质量和体质量增长趋势、食物利用率明显高于各自的空白对照组(P<0.05或P<0.01);而在不同奶源的6种婴儿配方奶粉和不同销售地区的6种婴儿配方奶粉之间在动物生长发育过程、体质量和体质量增长趋势、食物利用率、血常规指标及血液生化指标都没有明显的差别。结论:受试的12种中外婴儿配方奶粉在实验动物上引起的营养生物效应是相同的,没有优劣之分。

Abstract:

Objective: Six domestic brands (3 made from domestic milk sources and 3 from imported milk sources) and 6
foreign brands (3 marketed in the Chinese mainland and 3 purchased from Hong Kong) of infant formula milk powder were
used to feed SD rats for a comparative study of their biological effects in vivo. Methods: After 30-day feeding, nutritional
indexes of newly weaned rats were detected. Results: The body weights and food utilization of rat pups fed the different
brands of infant formula were significantly higher than those of the corresponding blank controls (P < 0.05 or P < 0.01).
In addition, no significant differences in body weight gain, gain trend, food utilization, routine blood parameters or blood
biochemical indexes were observed among 6 infant formulas from different milk sources and among 6 ones marketed in
different regions. Conclusion: These 12 brands of infant formula have the same biological effects in weaned rat pups.
