Abstract
Infants with acute gastrointestinal disturbance involving vomiting, diarrhea, dehydration, and acidosis, were able to retain N when it was given in adequate amts. in the form of casein hydrolysate, either intravenously or orally or both. Positive N balances were obtained when the N intake was 0.35 g./kg. of body wt./day. Retentions were greater when N intakes were greater, and were as large as those reported for well infants.
