Orientation of newborn mice to lactating females: Identifying biological substrates of semiochemical interest
International audience; Among mammals, odor-based communication between females and infants is decisive for neonatal survival. So far, the nature of odor substrates involved in the localization of the mother and their nipples is unknown in mice. The present study aims: (1) to evaluate the specific attractive value of lactating females to newborn mice, (2) to localize the abdominal region that is most attractive to pups, and (3) to identify odor substrates that support such attraction. Results showed that 5-6-day-old mice roam preferentially over the abdomen of lactating females than the abdomen of non-lactating females. In lactating females, pups are more attracted to abdominal areas compri…
