| Popis: | Abstract. A series of experiments was conducted to assess the hypothesis that chemical labels acquired by newborn kids from their mother may be important for the females' acceptance of their own offspring and rejection of alien young. In an initial experiment, recently parturient goats, Capra hircus L., were tested for their responses to their own familiar offspring and two alien kids of the same age: one that had been kept with its mother after birth (and therefore presumably labelled by her) and one that had been isolated since birth. While all 15 females accepted their own kid, 12 rejected both the labelled and unlabelled alien. Thus, labelling of kids by their mother is not necessary for their later rejection by an alien female who has established a selective bond with her own neonate. Kids in a second experiment were placed into a wire-mesh cage at birth that prevented their mother from licking or nursing them. At approximately 4·5 h postpartum, seven out of 18 goats failed to display maternal behaviour to either their own or alien kids. While all the remaining females accepted their own kid, significantly fewer (6/11) accepted an unlabelled alien. Although the cage manipulation appeared to disrupt maternal behaviour in a large proportion of females, it is none the less evident that mother goats are capable of recognizing their own offspring and discriminating it from an alien isolated kid, even when there is no opportunity for maternal labelling. Overall these two experiments suggest that when mothers and kids are left undisturbed after parturition, maternal labelling is not a necessary step for the establishment of selective care. |
