It has been found that mice do not evoke interspecies maternal aggression in lactating female rats even if the latter kill little rats of their litter. Putting mice in cages with rats bearing for the first time, and their progeny for 24 hours after labor, increases the frequency of infanticide and progeny leaving by female rats. The infanticide by lactating rats towards their own litter does not depend on whether these females exhibit muricid or not. Putting mice in cages with rats 3-6 days before bearing for the first time or during 24 hours after labor by repeatedly bearing rats does not influence the frequency of progeny leaving and infanticide reactions of female rats.
研究发现，即使哺乳期雌鼠会杀死自己窝里的幼鼠，小鼠也不会引发其种间母性攻击行为。将小鼠与首次产仔的大鼠及其产后24小时内的后代放在笼子里，会增加雌鼠杀婴和遗弃后代的频率。哺乳期雌鼠对自己窝里幼鼠的杀婴行为并不取决于这些雌鼠是否表现出杀鼠行为。在首次产仔前3至6天或经产大鼠产后24小时内，将小鼠与大鼠放在笼子里，不会影响雌鼠遗弃后代的频率和杀婴反应。
