Abstract

Many traits associated with domestication are suggested to have developed as correlated responses to reduced fear of humans. Tameness may have reduced the stress of living in human proximity and improved welfare in captivity. We selected Red Junglefowl (ancestors of all domestic chickens) for four...

Abstract

Ex situ conservation of threatened species may lead to behavioural adaptation, which can affect success of reintroduction attempts. In previous studies, we investigated the effects of captivity on the behaviour of red jungle fowl (Gallus gallus) and found that captive populations differed...

Although social behaviour is a major factor affecting the coping of poultry in production environments little is known about how it has been affected by intensive selection processes in fowl. We attempted to clarify selection effects on overall repertoire and occurrence of different social...

Social preferences of familiar over unfamiliar social stimuli in chicks may be used to measure sociality, a characteristic important for the welfare of poultry in commercial production. We studied social preferences and reaction to strangers in young White Leghorns and red jungle fowl (Gallus...

Abstract

Social coherence tendency is an important behavioural characteristic in young fowl related to an underlying social motivation that can be modified by breeding. Our aim was to investigate if selection for productive traits in a certain White Leghorn layer strain has influenced different components...

Abstract

Three different breeds of poultry, representing different degrees of domestication, were observed in semi-natural conditions in order to study differences in foraging behaviour, activity levels and social behaviours which could be caused by correlated responses to selection for increased...
