BACKGROUND Stress influences many aspects of animal behaviour and is a major factor driving populations to adapt to changing living conditions, such as during domestication. Stress can affect offspring through non-genetic mechanisms, but recent research indicates that inherited epigenetic modifications of the genome could possibly also be involved. (More)
White Leghorn layers (WL) show modified foraging strategies, compared to their ancestor, the red jungle fowl (RJF). Birds selected for high production may invest more resources into production traits and less in other biological processes. This may affect the capacity to adapt to new or variable environments. Thirty birds of each of RJF and WL were raised(More)
The main aim of this thesis was to study domestication effects on foraging behaviour in chickens and to investigate whether and how domestication and selection for high production have influenced adaptability in chickens. Two domestic strains of chickens (egg layers and meat type chickens) and their wild ancestor, the red jungle fowl (RJF) were compared in(More)
