Vaginocervical stimulation of ewes induces the rapid formation of a new bond with an alien young without interfering with a previous bond

Résumé

Ewes form a selective olfactory memory for their lambs offer 2 hr of mother young interaction following parturition Mothers will subsequently reject any strange lamb at suckling The present study investigated whether artificial vaginocervical stimulation (VCS) allows the formation of a selective bond with an unfamiliar Iamb and whether it interferes with the maintenance of the bond formed with the familiar lamb At 2 hr postpartum, mothers were separated from then familial lamb after having formed a selective bond with it and were given 10 nun of mechanical VCS. In the "VCS + lamb" group (n = 24) an unfamiliar lamb was left with the ewe for 2 hr whereas in the "VCS no lamb" group (n = 26) the mother was left alone for the same period of tune Ewes of the "no VCS" group (n = 14) did not receive any VCS In the majority of animals of the "VCS + lamb" group (23/24) VCS induced a complete acceptance of the unfamiliar lamb without any disruption of the bond previously formed with the familiar lamb VCS or 2 hr of reparation did not disrupt the maintenance of the selective bond initially formed with the familiar Iamb since all the ewes of the "VCS no lamb" and "no VCS'' groups accepted it at suckling (C) 2010 Wiley Periodicals, Inc Dev Psychobiol 52 537-544, 2010
