CABI Book Chapter Info
Cover for Development of the brain and behaviour.

The basic structure of the bird brain is shared with other vertebrates and is formed from five divisions. The spinal cord ascends to the hindbrain (myelencephalon and metencephalon), the midbrain (mesencephalon) and the forebrain (diencephalon and telencephalon). Every sensory system except for the ...

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

The purpose of this study was to analyze the effect of the presence of males on three measurements of fear and stress in females of several breeds of layers at 22 wk of age: tonic immobility duration, heterophil to lymphocyte ratio, and fluctuating asymmetry of four bilateral traits (toe length,...

Abstract

The aim of this trial was to determine the influence of aerial perches on welfare and production parameters in free-range laying hens. Five commercial free-range houses, each containing between 7000 and 8000 birds, were used. Each house and range area was split in half to create two treatments. In...

Abstract

Different lines of laying hens have undergone a strong selection pressure for productivity traits, which has been proposed as a potential cause of undesirable side effects like behavioural disorders. One reason for such behavioral changes might be due to energy trade-offs, as high productive laying ...

Abstract

Domestication of animals, regardless of species, is often accompanied by simultaneous changes in several physiological and behavioral traits (e.g. growth rate and fearfulness). In this study we compared the social behavior and emotional reactivity, as measured in a battery of behavioral tests, of...

Abstract

Fear can be a damaging factor, resulting in poor production and impaired animal welfare. Often fear reactions are elicited in situations that are in some way related to predator defense. As males have a guarding role, mixing the sexes might be a way of reducing fear in flocks of laying hens. Tonic...

Abstract

To gain further insight in risk factors related to feather pecking, this thesis investigated the effects of genetic background and social environment on feather pecking and related behavioural characteristics in laying hens. In several experiments, behaviour, performance and physiology of...

Abstract

Individual differences in behavioural responses are of growing interest in behavioural studies. The present study investigated the consistency of the individual differences over time and across social (social reinstatement responses) and non social test situations (tonic immobility response). Three ...
