Nitrogen and Fat Retention in Premature Infants Fed Breast Milk, "Humanized" Cow's Milk or Half Skimmed Cow's Milk

Three types of milk diet were tested in balance experiments using premature infants. They were: breast milk, “humanized” milk and half skimmed cow's milk containing more protein and less fat than the other' two milks. It was ascertained that protein retention was about the same on all three diets, while nitrogen elimination via the urine was much higher on the half skimmed milk. Fat retention was lowest on half skimmed milk, but this may have been due to the low fat content of that milk.
