Exploration of the hypothalamic–pituitary–adrenal function as a tool to evaluate animal welfare
Measuring HPA axis activity is the standard approach to the study of stress and welfare in farm animals. Although the reference technique is the use of blood plasma to measure glucocorticoid hormonesExpand
Stress and emotionality: a multidimensional and genetic approach
The use of behavioural tests aiming to assess the psychological components of stress in animals has led to divergent and sometimes arbitrary interpretations of animal behaviour. This paper presents aExpand
A multiple-test study of anxiety-related behaviours in six inbred rat strains
Recent studies have underlined the impact of genetic factors in anxiety profiles. In this context, we have initiated a series of experiments aiming to select, among six inbred strains of rats, a pairExpand
Corticosterone levels determine individual vulnerability to amphetamine self-administration.
Individual vulnerability to the reinforcing properties of drugs appears to be an essential characteristic predisposing humans to addiction. In animals, a greater behavioral reactivity to a mildExpand
Stress in farm animals: a need for reevaluation.
In animal husbandry, stress has usually been conceived as a reflex reaction that occurs ineluctably when animals are exposed to adverse environmental conditions, and which is the cause of manyExpand
Individual reactivity to novelty predicts probability of amphetamine self‐administration
The present study demonstrates a relationship between individual responses to environmental activation, such as novelty, and propensity to acquire amphetamine self-administration. Locomotor activityExpand
Differential effects of social stress on central serotonergic activity and emotional reactivity in Lewis and spontaneously hypertensive rats
Social stress by repeated defeat has been shown to be endowed with neuroendocrine and behavioural effects that render this stress model useful to identify adaptive mechanisms. Among these mechanisms,Expand
Genetics of adaptation and domestication in livestock
Abstract In this review, we assess the current state of knowledge on domestication of the major livestock species. We present first some historical background on location and dates of domesticationExpand
Identification of female-specific QTLs affecting an emotionality-related behavior in rats
The influence of genetic factors on psychological traits and disorders has been repeatedly demonstrated; however, the molecular mechanisms underlying such an influence remain largely unknown.Expand
Anxiety- and activity-related effects of diazepam and chlordiazepoxide in the rat light/dark and dark/light tests
We have investigated, through factor analysis, anxiety- and activity-related variables in rats placed in the light/dark box. Thus, vehicle-, diazepam (DZ)-, and chlordiazepoxide (CDP)-treated ratsExpand
