Assessment of positive emotions in animals to improve their welfare
TLDR
Play, affiliative behaviors and some vocalizations appear to be the most promising convenient indicators for assessing positive experiences in laboratory and farm animals under commercial conditions. Expand
A critical review of fear tests used on cattle, pigs, sheep, poultry and horses
TLDR
This review attempts to establish the level of repeatability and validity found for fear tests used on cattle, pigs, sheep and goats, poultry and horses, and focuses on the three most common types of fear tests: the arena test, the novel object test, and the restraint test. Expand
Fear and Fearfulness in Animals
  • A. Boissy
  • Psychology, Medicine
  • The Quarterly Review of Biology
  • 1 June 1995
TLDR
The great variability in behavior and in physiological patterns generally associated with emotional reactivity is described, suggesting that fearfulness could be considered a basic feature of the temperament of each individual, one that predisposes it to respond similarly to a variety of potentially alarming challenges but is nevertheless continually modulated during development by the interaction of genetic traits of reactivity with environmental factors, particularly in the juvenile period. Expand
Emotions in farm animals: a new approach to animal welfare in applied ethology
TLDR
An analysis of the emotional repertoire of farm animals is proposed in terms of the relationship between the evaluative process of the event on the one hand and the behavioural and physiological responses on the other hand. Expand
Genetic correlations between temperament and breeding traits in Limousin heifers
TLDR
Estimates of genetic correlation between temperament traits indicated that, genetically, aggressive animals also attempt to escape a lot, so a slight trend of less fearful heifers also being more productive, mainly because of a higher reproduction and calving performance, and, to a lesser extent, because of higher maternal abilities. Expand
Genetics of adaptation and domestication in livestock
TLDR
The characteristics that favoured domestication are described, especially gregariousness, precocity of young and diet, and major behavioural modifications observed during domestication, including relationships with humans and predators, and social, feeding, reproductive and maternal behaviours as well as morphological changes. Expand
Release from restraint generates a positive judgement bias in sheep
Abstract The study of judgement biases in animals has attracted interest as a way of potentially measuring emotional states by being able to detect pessimistic-like or optimistic-like evaluations ofExpand
The effect of repeated testing on judgement biases in sheep
TLDR
The effect of time suggests that sheep learnt that the ambiguous locations were unrewarded, which supplies evidence of a limitation identified in current judgement bias methodology, due to repeated testing, which has the potential to provide misleading results. Expand
The relationship between farmers' attitude and behaviour towards calves, and productivity of veal units
TLDR
It is concluded that for veal farmers, a positive attitude towards calves, apositive behaviour towards them, and good production results are linked. Expand
