Abstract
For the improvement upon humanized milk powder, the investigation was made on the frequency of appearence of Bifidus flora in infants by the feeding of some samples of new types of composition in which the lactose-protein ratio was from 3.7 to 4.6.
Especially, the influence by the difference of casein-albmin-globuline ratio and of addition with Bifidus factor (β-Ethy1-N-Acetyl-D-glucosarnine) was examined.
As the results, however a remarkable effect and a definite conclusion could not be obtained in any case, because of the difference in individual condition of tested infants.
