From in-vitro studies of breast and cow's milk preparations, and of the faeces from breast-fed and bottle-fed infants, a number of factors seemed likely to influence the production and maintenance of a lactobacillary flora and low pH in the faeces of newborn infants. These were mainly attributable to the nature of the feed. It is suggested that responsible factors in breast milk include its high lactose, low protein, low phosphate content, together with its poor buffering capacity. Importance is also attached to the fact that breast milk seems to provide a fluid feed of small bulk and low residue, and that its use is unlikely to include periods of starvation. Cow's milk, on the other hand, which has a low lactose, high protein, high phosphate content, and a high buffering capacity, is a relatively bulky, high-residue feed. Feeding regimens which employ it are likely to include periods of starvation.
