来自幼鼠的刺激维持了产后期的母性行为。嗅觉线索强烈参与了母性行为的一个特定组成部分：舔肛门生殖器（MAGL）。除了嗅觉刺激外，幼犬发出的超声波叫声对确保幼犬存活至关重要。幼犬在困境中发出叫声。在第一个实验中，围绕MAGL序列记录幼崽的叫声。在2/3的情况下，这些叫声似乎诱导了包皮切除幼鼠和完整幼鼠的母体的MAGL行为，但包皮切除幼鼠在MAGL序列结束时单独再次发出叫声。在第二个实验中，幼鼠在AGL序列之前发出的超声波叫声被记录下来，并在玻璃皿选择测试中回放给母鼠。无论幼鼠的处理（包皮切除或假手术），当听觉线索（幼鼠的超声波叫声）和嗅觉线索（DP）相结合时，母鼠对浸渍有十二烷基丙酸酯（DP）的滤纸表现出特定的摄食行为。探讨了超声波叫声与肛门生殖器气味在MAGL行为中的协同作用，认为超声波叫声可能是MAGL行为的诱导因素，而DP可能是MAGL行为的调节因素。
Stimuli from pups maintain maternal behavior in the postpartum period. Olfactory cues are strongly involved in a particular component of maternal behavior: anogenital licking (MAGL). In addition to the olfactive stimulus, ultrasonic calls from pups are critical in ensuring pup survival. Pups emit vocalizations in distress situations. In a first experiment, pups' calls are recorded around MAGL sequences. In 2 out of 3 cases these calls appear to induce MAGL behavior from the dam with preputialectomised pups as well as with intact pups, but preputialectomised pups alone call again at the end of MAGL sequences. In a second experiment, ultrasonic calls from pups emitted just before AGL sequences were recorded and played back to dams in a glass-dish selection test. Whatever the pups' treatment (preputialectomised or sham), dams showed the specific ingestive behavior towards filter paper impregnated with dodecyl propionate (DP) when auditory cues (pups' ultrasonic calls) and olfactory cues (DP) were combined. The coordination of pups' ultrasonic calls and anogenital odor in MAGL behavior is discussed, ultrasonic calls might be an inducing factor and DP the regulating factor.
