10只喂食混合鼠乳的幼鼠和9只喂食人工配方的幼鼠在40 h龄时比出生时处死的12只幼鼠具有显著更重的胃和肠，其中含有更多的DNA和RNA。母乳喂养的动物比人工配方喂养的动物有明显更重的肠道，肝脏和肾脏。母乳喂养的幼犬的肠道含有更多的DNA和RNA，RNA：DNA的比例低于人工配方奶喂养的幼犬。因此，在控制热量摄入和喂养方式的情况下，天然牛奶比人工配方奶更能促进新生儿肠道发育。
Ten rat pups fed pooled rat milk and 9 pups fed artificial formula had significantly heavier stomachs and intestines that contained more DNA and RNA by 40 h of age than 12 pups sacrificed at birth. Breast-milk-fed animals had significantly heavier intestines, livers and kidneys than animals fed artificial formula. The intestines of pups fed breast milk contained more DNA and RNA with a lower RNA:DNA ratio than the intestines of pups fed artificial formula. Hence, when caloric intake and mode of feeding are controlled, natural milk enhances neonatal intestinal growth more than artificial formula.
