Individual olfactory signatures as major determinants of early maternal discrimination in sheep.

Developmental psychobiology - 1 Apr 1991

Abstract excerpt

Responses of recently parturient ewes to their familiar versus separated (i.e., unfamiliar) twin lambs were observed in an attempt to elucidate further the characteristics of the phenotypic traits (signatures) mediating maternal recognition and bonding. Ewes responded more positively to their familiar lamb than to its twin that had been isolated at birth. Nonetheless, those same mothers also discriminated between...
