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.
