营养不良的母鼠在怀孕和哺乳期的大部分或整个过程中每天都被喂食，大约是对照组优质饮食的一半。它们在哺乳期间每天占据和离开巢穴的模式与对照组有很大不同。产后4、6、8、10天进行回收试验。喂养不足的母亲在第 8 天和第 10 天接回幼崽的效率低于对照组，并且在测试期间舔幼崽的可能性也较小。它们还花费更多的时间用后腿站立。在营养不良的雌性中，回收的幼崽数量与饲养时间呈负相关。讨论了母亲行为差异对后代发育的重要性。
Undernourished mother rats were given daily meals throughout most or all of pregnancy and lactation, comprising about half the amount of a good quality diet taken by controls. Their daily pattern of nest occupation and desertion during lactation was quite different from that of controls. Retrieving tests were carried out at 4, 6, 8 and 10 days after parturition. Underfed mothers were less efficient than controls in retrieving their young on days 8 and 10, and were less likely to lick their young during the test period. They also spent much more time rearing on their hind legs. Among undernourished females the number of young retrieved was negatively correlated with duration of rearing. The significance of the differences in maternal behaviour for offspring development is discussed.
