“…In sheep, parentally naive females respond aggressively towards young conspecifics whether virgin or pregnant (Le Neindre et al, 1979;Keverne et al, 1983;. In this species, distension of the birth canal triggers maternal behaviors (Keverne et al, 1983;Krehbiel et al, 1987;. The same may be true for prairie voles as preliminary evidence suggests that voles are more likely to be parental if the offspring is allowed to descend into the birth canal (Hayes and de Vries, 2005).…”

In prairie voles (Microtus ochrogaster), most virgin females are infanticidal. To determine the onset of maternal responsiveness, female prairie voles were tested for maternal behavior as virgins and at different times throughout pregnancy. Female voles that were infanticidal as virgins by and large remained infanticidal throughout pregnancy. In contrast, about 30% of voles that were maternal as virgins became infanticidal during pregnancy. To test whether events associated with parturition facilitate the onset of maternal behavior, females had their litters delivered by Caesarean section within a day of expected delivery or were allowed to give birth naturally with sham surgery occurring shortly before or after birth. Females that gave birth naturally were fully maternal and did not attack unrelated pups, but females subjected to artificial delivery remained infanticidal. This suggests that events closely related to parturition are crucial for full development of maternal behavior in female prairie voles.

“…For instance, in nulliparous, nonpregnant ewes, neither vaginocervical stimulation nor intracerebroventricular injections of oxytocin, opiates, or corticotrophin releasing factor (CRF) induce acceptance of the lamb . Peridural anesthesia that prevents vaginocervical stimulation has more profound effects in the onset of maternal behavior in primiparous females than in multiparous ewes (Krehbiel, Poindron, Lévy, & Prud'Homme, 1987). Finally, acceptance of the lamb by primiparous, but not multiparous, ewes is disturbed by disruptions of the main olfactory system (Lévy et al, 1995b) and removal of amniotic fluids from the neonate .…”

Maternal experience influences the establishment of visual/auditory, but not olfactory recognition of the newborn lamb by ewes at parturition

Maternal behavior in sheep is characterized by the rapid establishment of individual recognition of the lamb through the use of different sensory modalities. Olfactory recognition mediates acceptance at suckling whereas visual/auditory cues are involved in recognition from a distance. This study investigates (a) the timing of both types of recognition and (b) whether they can be influenced by maternal experience. Olfactory recognition was assessed at lambing, 30 min, 1, 2, or 4 hr postpartum by presenting successively an alien and the familiar lamb. Recognition at a distance was assessed at 6, 8, and 12 hr postpartum by using a two-choice test between the familiar and an alien lamb. A majority (33/51) of ewes showed selectivity at suckling as early as 30 min after parturition, and no differences due to maternal experience were observed. By contrast, in the two-choice recognition test, multiparous ewes showed a preference for their familiar lamb at 6 hr whereas primiparous mothers did so only after 24 hr of mother-young contact: The performance of biparous mothers was intermediate. Thus, both types of recognition can be rapidly established after parturition, and maternal experience has a differential effect on the dynamics of these learning processes.

“…The stretching of the birth canal as the fetus descends activates innervating sensory fibers, sending signals through the spinal cord to the brain thereby causing the release of various neurochemicals ( e.g. , Ferguson's reflex; Levy et al, 1995; Berkley, Robbins & Sato, 1988; Berkley, Hotta, Robbins & Sato, 1990; Robbins, Sato, Hotta & Berkley, 1990; Krehbiel, Poindron, Levy & Prud'Homme, 1987; Ferguson, 1941). These neurobiological changes facilitate the birth process and are involved in changes in emotionality and induction of maternal behaviors (Kendrick et al, 1991; Da Costa et al, 1999; Levy, Kendrick, Keverne, Piketty & Poindron, 1992).…”

Role of pelvic sensory signalling during delivery in postpartum mental health

Background-Animal research demonstrates that pelvic sensory signaling at parturition initiates behavioral and emotional changes that are protective for mother and offspring. In contrast, research with humans has found no effect of cesarean delivery (i.e., procedure that blocks pelvic signaling) on mother's mental health. The lack of effect may reflect little consideration for the use of epidurals, another intervention that blocks pelvic signaling. The following study examines whether blocking pelvic signaling during delivery predicts postpartum depression symptomatology.
