Abstract
Chemical lavage of the nipples of anesthetized maternal rats virtually eliminated suckling by their 4- to 5-day-old pups. Normal suckling was immediately reinstated, however, by painting a vacuum distillate of the wash or of pup saliva onto the nipples. Thus, a substance necessary to direct and release suckling, possibly rat pup saliva, appears to coat the nipple surface.
摘要
对麻醉的母鼠乳头进行化学灌洗，实际上会使4至5日龄幼崽不再进行哺乳。然而，通过将灌洗液或幼崽唾液的真空蒸馏液涂抹在乳头上，正常哺乳会立即恢复。因此，一种指导和引发哺乳所必需的物质，可能是幼崽唾液，似乎会覆盖在乳头表面。
