Abstract: This formula consisted of millet meal , wheat flour , mixed with appropriate amount of egg, soybean flour , and fortified with calcium carbonate and riboflavin. Animal experiment: 30 weaning wistar rats were randomly divided into 3 groups: (A) casein group. (B) formula group, (C) No nitrogen group. The results showed that body weight gain, Hb, serum protein content, Lengths of cuboid and shinbone were not significantly different between of group A and B (P>0. 05) .The calibrated PER, TD, BV and NPU group A were 2. 5, 92. 5%, 74. 1%, 68. 5% and of group B were 2. 24, 86. 2% , 69. 1 % and 61.3% respectively. Both groups obtained the results of positive nitrogen balance, no significant statistical difference. was found. These data demonstrate that this formula is able to promote the growth of weanling rats and retain positive body nitrogen.
