  • No suffering of gastrointestinal diseases within 1 month (CCDC recommendations);
  • Parents agreeing to use one of the recommended infant formulas (no probiotic, if with prebiotics, exclude it when there is GOS over 2g/100g or FOS inside);

  • Infants with serious diseases, such as cardiovascular, cerebrovascular, liver, kidney and hematopoietic system diseases and internal secretion diseases, and those with mental disorder (CCDC recommendations);
  • Infants administering other drugs during the administering of the study products, thus impossible to judge the efficacy or influencing the judgment of results (CCDC recommendations);
  • Infants known to have current or previous illnesses/conditions or intervention which could interfere with the study (impacting tolerance and/or growth), such as gastrointestinal malformations, chronic diarrhoea, malabsorptive syndrome, malnutrition, congenital immunodeficiency, or major surgery, as per investigator's clinical judgment;
  • Infant under oral antibiotic treatment at V1 visit and within the 4 weeks before V1
  • Infants who used any medication or nutritional supplements (including probiotics, prebiotics etc, except for infant formula) in the 4 weeks preceding study start;
  • Infants who have ever consumed the test product;
  • Infants who have medical conditions for which a special diet other than standard (non hydrolyzed) cow's milk-based infant formula is required (such as cow's milk allergy, soy protein allergy, fish protein allergy, egg protein allergy, lactose intolerance, galactosemia);

Primary Outcome Measures
NameTimeMethod
Proportion of Participants Achieving the modulatory effect on the GI tract flora composition after the intervention.From Baseline to week 4

GI tract flora include Bifidobacterium, Lactobacillus, Clostridium perfringens, Enterococcus, Enterobacter, Bacteroides. Modulatory effect of GI tract flora composition was defined as two definitions. The first definition is that Lactobacillus and/or Bifidobacterium increases significantly, Clostridium perfringens decreases or has no change and Enterococcus, Enterobacter, Bacteroides has no obvious change. The other is that Lactobacillus and/or Bifidobacterium increases significantly, Clostridium perfringens decreases or has no change, Enterobacter and/or Enterococcus, Bacteroides increases significantly, but the amplification less than Lactobacillus/Bifidobacterium.
