Figure DEST_PATH_IMAGE001
And (3) analyzing test results:
1. as can be seen from the combination of example 1 and table 1, after the compound nutrient prepared in preparation example 1 is added to the prepared milk powder, it can be seen from the experimental data that the brain nerve development of the young mouse fed with the compound nutrient in example 1 is better than that of the young mouse fed with the milk of the mother mouse after 5 days, which indicates that the compound nutrient prepared in preparation example 1 has a strong promoting effect on the growth and development of the young mouse;
2. as can be seen by combining examples 1 to 3 with Table 1, the effects of regulating the amounts of the respective nutrients within a certain range on the promotion of the neural development of rat pups are substantially the same;
3. as can be seen by combining examples 1 and 4 and table 1, the composite nutrients in the modified milk powder, which contain nicotinic acid, choline and taurine, and ribose, amino sugar and nucleotide, have substantially the same promoting effect on rats;
4. as can be seen from example 5 in combination with table 1, example 5 is the most preferable example, and thus it can be demonstrated that the promotion effect on the neural development of rat pups is the strongest when nicotinic acid, choline, taurine, ribose, amino sugar and nucleotide are contained in the complex nutrient;
5. as can be seen by combining examples 5-7 with Table 1, the growth-promoting effect on rat pups is poor when nicotinic acid and choline or ribose and amino sugar are absent in the complex nutrients, thus illustrating the synergistic effect of the substances of claims 2 and 3 on the development of rat pups nerves;
6. when the compound nutrient is not contained in the prepared milk powder, the promotion effect on the growth and development of the young rat is poor, and the growth and development of the rat and the young rat can be delayed to a certain extent;
7. as can be seen by combining example 1 and comparative examples 2 to 4 with Table 1, the effect of promoting the growth and development of rat pups was significantly inferior to that of example 1 when the formulated milk powder did not contain organic salts, beneficial bacteria and vitamins, indicating the essential ingredients in the formulation of milk powder containing organic salts, beneficial bacteria and vitamins.
