据报道，注射到 10 天大的 Sprague-Dawley 大鼠体内的放射性水第二天可以从其母亲的血液中回收。通过结扎注射的幼鼠的尿道，这种水的转移几乎被消除了，这一结果表明母鼠消耗了它们后代的尿液。通过结扎一窝中所有幼崽的尿道来防止尿液消耗，使母鼠仅在 24 小时禁水时产生的血浆容量不足增加了一倍，并导致等渗盐水增加，但禁水后的水摄入量却没有增加。在剥夺幼崽尿液后，母鼠的每日饮水量增加，并且在剥夺饮水后，它们舔幼崽的行为也会增加。 3 项实验的结果表明，母鼠的尿液消耗会产生生理和行为后果，并表明幼鼠舔在某种程度上是一种摄入行为。（16 参考文献）（PsycINFO 数据库记录 (c) 2016 APA，保留所有权利）
Reports that radioactive water injected into 10-day-old Sprague-Dawley rats could be recovered the following day from their mothers' blood. This transfer of water was nearly eliminated by ligating the injected pups' urethras, a result indicating that mother rats consume their offspring's urine. Preventing urine consumption by ligating urethras of all pups in a litter doubled the plasma volume deficit in dams produced by 24 hrs of water deprivation alone and led to increased isotonic saline but not water intake following water deprivation. Dams' daily water intake increased after they were deprived of pup urine, and their pup-licking behavior increased following water deprivation. Findings from 3 experiments indicate that urine consumption by mother rats has both physiological and behavioral consequences and suggest that pup licking is, in part, an ingestive behavior.(16 ref)(PsycINFO Database Record (c) 2016 APA, all rights reserved)
