摘要

The inability of animals to cope with their social environment in husbandry systems could be a major source of problems for both animal welfare management and economy. In this context, previous studies selected lines of domestic Japanese quail diverging for their level of social reinstatement, hypothesizing that quail with high levels of social motivation would adapt better to crowded social situations than quail with low levels of social motivation. However, these selections were based only on social motivation evaluated in young birds. As behavioural traits can vary with age, this study analysed the persistence of selected social traits into adulthood. With this in mind, we used several behavioural tests to estimate social motivation of adult females from selected lines for high social reinstatement (HSR, n=24) and for low social reinstatement (LSR, n=24). The tests were: open-field tests, emergence tests, separation tests, runway tests and confrontation tests. As birds' behaviour in these tests can be influenced by the emotive characteristics of the subjects, we measured the emotional reactivity of quail not only during these tests but also in specific emotive tests: tonic immobility tests. Our results showed that the social motivation characteristics of birds persist in adulthood. Adult HSR females still presented a higher social motivation than adult LRS females: their response to social isolation was stronger and their motivation to reach conspecifics and to stay close to them was higher. However, the behavioural expression of social motivation appeared to be modified during development. Whereas vocal behaviour reflected the social motivation of chicks, in isolated contexts, this characteristic was not observed in adult quail.
