L'allaitement chez les Babouins Olives : apports sur la compréhension de la lactation chez les primates

Abstract : Objective: the aim was to identify what is learned or instinctive in the breastfeeding of non-human primates. Material and Method: a prospective observational study was conducted at the primatology station of Rousset sur Arc (CNRS) between May and July 2019 corresponding to 58 hours of observations. It included 12 pairs of Baboon Olive motherchild between the ages of 0 and 45 days. In this work, the quality of breastfeeding was evaluated thanks to the duration of suckings, the maintenance of the infant by the mother, the number of stalls of the new-born during sucking. Parity and age of the infant were used as a proxy for the mothers' experience. The ANOVA method was used for the statistical analyses. To assess the significance of the various correlations studied, a significance threshold was defined by a p <0.05. Result: The increase in parity is correlated with better maintenance of the new-born by its mother (p = 0.007). The more experienced females spontaneously reposition themselves during the suction compared to the primiparous (p = 0.0003 and r = 0.98). Discussion: However, the notion of learning is difficult to assess in non-human primates, especially through the possible bias resulting from interaction with the other members of the group. Conclusion: These results therefore suggest that the quality of posture could be linked to a form of learning as in modern humans.
