先前描述的实验表明，在出生后的第一个24小时内，哺乳仔猪的肠粘膜的重量和蛋白质大量增加。这并没有发生在饥饿的小猪身上。这一结果可能部分是由于在吸收过程中粘膜中包含了蛋白质分子。兔子出生后不会吸收大量的蛋白质，现在已经在它们身上重复了这个实验。在最初的24小时内，哺乳兔的胃肠道也迅速生长，但在仅给予水的兔中同样没有，这与初乳含有刺激胃肠道生长的因子的建议一致。由于脂质和蛋白质的掺入，哺乳动物的大脑重量增加。在饥饿的兔子中，它的体重也增加了，这表明它在生长速度达到顶峰时对营养的高度重视。
An experiment described previously showed a large increase in weight and protein of the intestinal mucosa of suckling piglets during the first 24 h after birth. This did not take place in piglets that were starved. The results might have been partly due to the inclusion of protein molecules in the mucosa in process of absorption. Rabbits do not absorb large quantities of protein after birth, and the experiment has now been repeated on them. The gastrointestinal tract of suckled rabbits also grew rapidly in the first 24 h, but again not in those that were given only water, which is in line with the suggestion that colostrum contains a factor which stimulates the growth of the gastrointestinal tract. The brain gained weight in the suckled animals, due to incorporation of lipid and protein. It gained weight too in the starving rabbits, demonstrating its high priority for nutrients at a time when its growth velocity is at its peak.
