Abstract:
This infant cereal chiefly consisted of rice meal, fullfat milk powder, rice germ and dried yeast, and fortified with ferrous lactate and calcium carbonate. This mixture contained 14.1% protein, 8.6% fat, 64.3% carbohydrate, 750mg% calcium, 10mg% iron, 1.0mg% zinc and proper amount of various kinds of vitamins.1. Growth test; 84 weaning SD rats were randomly divided into 6 groups:(A) Infant cereal group;(B) Control I; (C) Control II; (A') Infant cereal group; (B') Control I; (D) Casein group. The latter three groups contained 10% protein which were designed for calculating PER. All these different preparations were fed to 6 groups for 4 weeks. The results showed that the body weight gain, the FE, CE and PER were not significantly different between group A and B but there were significant difference between group A and C. The Hb was increased from 11.76g% ( ) and 11.46g%() to 14.30g% and 14.46g% respectively in group A. The bones developed well and no decalcification occured.2.Nitrogen balance test:(A). Infant cereal group; (B) Control I. The results indicated that the TD, BV and NPU of group A were 98.08%, 85.73% and 84.09% and of group B were 97.81%, 87.51% and 85.59% respectively. Both groups obtained the results of positive nitrogen balance, no significant statistical difference. The contents of hepatic and body nitrogen of two groups were also not significantly different.These data demonstrate that this infant cereal is able to promote the growth of weanling rats, to retain positive body nitrogen and to prevent the occurrence of anemia and rickets.
