Breastmilk is the best food for low birthweight babies for the first critical week(s) of life. In subsequent weeks, during rapid growth, formulas specially designed for this group of infants may be superior to ordinary breast milk substitutes. Modifications comprise the composition of carbohydrates, fats and proteins. Requirements of minerals and vitamins are probably different from those in babies with normal birthweights. A controlled study was done of feeding a formula containing unmodified cow's milk protein (mainly curd) as compared to one containing the same amount of modified cow's milk protein (curd and whey). Using as criteria anthropometry, nitrogen balance studies and plasma amino acid levels certain advantages were found when feeding the low birthweight babies the whey predominant formula.
母乳是低体重儿出生后第一个关键周的最佳食物。在随后的几周里，在快速生长阶段，专门为这组婴儿设计的配方奶可能优于普通母乳替代品。这些调整包括碳水化合物、脂肪和蛋白质的成分。矿物质和维生素的需求可能与正常出生体重的婴儿不同。我们进行了一项对照研究，比较了喂养含未改性牛奶蛋白（主要是凝乳）的配方奶和含等量改性牛奶蛋白（凝乳和乳清）的配方奶。以人体测量学、氮平衡研究和血浆氨基酸水平为标准，发现给低体重儿喂养以乳清为主的配方奶有一定优势。
