In a companion paper, we reported the persistence of an increase in active nursing and nursing-related behaviors in rats that were rehabilitated following prolonged intergenerational malnutrition. The rehabilitated litters contained females and pups fed an adequate diet for up to three generations after a history of malnutrition. In the current study, a 2 X 2 cross-over design was used during the lactation period in which rehabilitated mothers suckled rehabilitated pups or well-nourished control pups, and control mothers similarly suckled rehabilitated or control pups. We found that maternal factors were dominant in determining the amount of active nursing, and that pup factors modified the maternal influence on other lactation-related behaviors.
在一篇配套论文中，我们报道了经历长期代际营养不良后康复的大鼠，其主动护理及与护理相关行为的增加持续存在。这些康复的窝仔包含雌性和幼崽，在经历营养不良后，它们连续三代都被喂食充足的饮食。在本研究中，哺乳期采用了2×2交叉设计，即康复的母鼠哺育康复的幼崽或营养良好的对照幼崽，对照母鼠同样哺育康复的或对照幼崽。我们发现，母体因素在决定主动护理量方面占主导地位，而幼崽因素则改变了母体对其他泌乳相关行为的影响。
