当通过位于口前的口腔插管进行输注牛奶时，1-20日龄的幼鼠主动摄取饮食，其摄取量与剥夺时间的长短有关。幼犬在摄入大量牛奶后，其摄食反应增强。此外，1，3和6日龄的幼崽，当24小时剥夺，表现出强烈的行为激活，以响应牛奶输注。行为激活似乎主要是由味道和吞咽的机会刺激的。牛奶输注没有产生激活在老年幼犬，他们的行为更专门摄食和食物的指导。从出生开始，大鼠幼崽就能够进行主动形式的摄食，独立于母亲的正常哺乳;这种摄食受生理因素控制;食物在年幼动物中具有唤醒特性;随着幼崽长大，它们的摄食反应从一般性和非定向激活细化为特异性和定向摄食反应。
When milk infusions were made through oral cannulas located in the front of their mouths, rat pups from 1-20 days of age actively ingested the diet and their intake was related to the length of deprivation. Pups increased their ingestive responding after they had consumed large volumes of milk. In addition, 1, 3 and 6 day old pups, when 24 h deprived, exhibited an intense behavioral activation in response to milk infusion. The behavioral activation appeared to be stimulated primarily by taste and the opportunity to swallow. Milk infusions did not produce activation in older pups; their behavior was more exclusively ingestive and food directed. From birth, rat pups are capable of an active form of ingestion, independent of normal suckling from the mother; such ingestion is controlled by physiological factors; food has arousing properties in young animals; and as pups grow older, their ingestive responding is refined from a generalized and nondirected activation to specific and directed feeding responses.
