Influence of mothering on emotional and social reactivity of domestic pullets

Résumé

The aim of this study was to determine whether different early mothering experiences influenced emotional and social reactivity of sub-adults and adults in domestic fowl. We compared two types of individuals: brooded and non-brooded pullets. Brooded pullets were reared by a maternal hen during their first 53 days of life. Observations and tests were made between 14 and 29 weeks of age. Our results revealed that brooded pullets were less neophobic than non-brooded pullets as they went nearer a novel object. Nevertheless, no differences were found between the two sets when pullets were placed in a very novel situation (tonic immobility (TI) test, open-field test). Social reactivity also differed: brooded pullets, more than non-brooded pullets, sought the proximity of a conspecific. They interacted more agonistically when they encountered unfamiliar individuals and their peck-order was more linear. These results reveal that maternal influence remained detectable after the end of maternal contact. (C) 2002 Elsevier Science B.V. All rights reserved.
