Maternal behaviour in sheep and its neuroendocrine regulation

Keverne, B, Kendrick, KM·1994·Acta Paediatrica

Abstract

Non‐parturient sheep, hormonally primed and presented with newborn lambs are, at best, indifferent to them and if approached by the lamb may show violent rejection. However, non‐gestant ewes primed with oestrogen and progesterone, but given vaginocervical stimulation, do show a rapid onset in maternal behaviour. This stimulation is ineffective in promoting maternal behaviour with epidural anaesthesia. Vaginocervical stimulation increases the release of oxytocin into cerebrospinal fluid and in‐vivo microdialysis has revealed high levels of oxytocin release in limbic brain areas known to be important for maternal behaviour. Oxytocin, when given intraventricularly, produces the full complement of acceptance and suckling behaviour in non‐gestant ewes. Although ineffective when given alone, opioids potentiate the release of oxytocin in the limbic brain and increase the intensity of maternal responding, while the opioid receptor blocker, naltrexone, prevents both maternal induction and oxytocin release. This neural basis for maternally motivated behaviour may be equally relevant to human behaviour, although the mechanisms available for addressing these peptidergic systems have clear differences.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Opioid agonists promote mother-offspring bond formation and later maternal behavior in sheep, while opioid antagonists prevent both mother-offspring and offspring-mother bonding.

    “Opioid agonists potentiate the formation of mother-offspring bonds and subsequent maternal behavior in sheep, while opioid antagonists prevent both mother-offspring and offspring-mother bonding (Kendrick and Keverne 1989; Keverne and Kendrick 1994; Shayit et al 2003).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
