 This study evaluates the early infant feeding in the infant intestinal microecology and the long term health. 300 healthy term newborns were involved into the study on its first stage. Depending on the type of feeding the infants were divided into 3 groups with random allocation to one of the formula feeding groups: the group A included 100 infants consuming the formula supplement with superior quality whey protein, the group B -100 infants fed with a standard formula, and the group C -100 infants who were breastfed.
