哺乳是哺乳动物中唯一常见的行为。在新生的白化大鼠中，它最初是由母体在分娩期间沉积的羊水引起的。随后的哺乳是由幼鼠乳头上的唾液刺激的。直到2周龄的幼鼠才出现对母乳量的内部控制，此时胃胀、乳汁、全身脱水和肠道激素胆囊收缩素抑制了母乳的摄入量。对哺乳食欲控制的发展似乎与圆满控制的发展平行。直到大约2周龄，幼鼠选择以与哺乳乳头相同的频率吮吸非哺乳乳头。此后，泌乳乳头被一致选中。这些研究表明，实验室大鼠和其他哺乳动物的哺乳行为存在差异和共性。
Suckling is the only behavior that is common among mammals. In newborn albino rats it is originally elicited by amniotic fluid deposited by the mother during parturition. Subsequent suckling is stimulated by saliva deposited on the nipples by the infant rats. Internal controls over the volume of milk suckled do not appear until infant rats are about 2 weeks of age at which time gastric distension, milk, systemic dehydration, and the intestinal hormone cholecystokinin suppress milk intake derived through suckling. The development of controls over suckling appetite appears to parallel that of consummatory control. Until about 2 weeks of age infant rats choose to suckle a nonlactating nipple with the same frequency as a lactating nipple. Thereafter, the lactating nipple is unanimously chosen. These studies suggest differences and commonalities in the suckling behavior of laboratory rats and other mammals.
