In gregarious species like cattle, the presence of partners often affects fear-related reactions. The first experiment investigated whether behavioral and physiological responses to stress depend on the emotional state of the partner. Aubrac heifers were presented with food in a novel environment. Compared to heifers in the presence of a companion that had been previously habituated to the environment without receiving shocks, those in the presence of a companion animal that had previously… Expand
Social buffering in horses is influenced by context but not by the familiarity and habituation of a companion
TLDR
It is proposed that circumstances which permit greater contextual processing may facilitate demonstration of behavioural effects of social buffering, whereas buffering in response to startling events may be manifest only during post-event physiological recovery. Expand
Behavioural responses of cattle to the odours of blood and urine from conspecifics and to the odour of faeces from carnivores
TLDR
Dog faecal odour was the only odour to induce behavioural changes prior to feeding, involving also an increase in sniffing air and in stretched locomotion, which may suggest that sniffingAir is the more general response to an odour added to the environment, and that stretching locomotion is the behavioural expression of the perception of an odours that indicates a potential danger. Expand
Predator odour per se does not frighten domestic horses
TLDR
Investigation of how horses respond to urine from wolves and lions, blood from slaughtered conspecifics and fur-derived wolf odour, and a sudden auditory stimulus indicates that predator odour per se does not frighten horses but it may cause an increased level of vigilance. Expand
A novel protocol to measure startle magnitude in sheep
Abstract Temperament is a trait of interest as it impacts ease of handling, production and reactivity to stressful situations. Excessive behavioural reactivity, as an aspect of temperament, may leadExpand
Alarm pheromone enhances stress-induced hyperthermia in rats
TLDR
It is suggested that an alarm pheromone enhances stress responses of conspecific animals both behaviorally and physiologically, and that these effects are mediated via activation of the accessory olfactory bulb. Expand
Alarm scent-marking during predatory attempts in the Cabrera vole (Microtus cabrerae Thomas, 1906)
TLDR
It is suggested that during predatory attempts, Cabrera voles release an alarm pheromone in their urine-marks and the putative alarm phersomone persists in the field affecting conspecifics’ activity for several days. Expand
In search of stress odours across species: Behavioural responses of rats to faeces from chickens and rats subjected to various types of stressful events
TLDR
Using the ability of rats to distinguish between faeces odours from stressed and non-stressed conspecifics, it is investigated whether rats could detect stress status in another species (the chicken), which would suggest a commonality in odorous stress signatures across species. Expand
A few days of social separation affects yearling horses’ response to emotional reactivity tests and enhances learning performance
TLDR
Data suggest that the better performance of isolated yearlings could be explained by a decrease in their emotional reactivity, which is less reactive to novelty, to social separation and to suddenness than controls. Expand
Can emotional reactivity predict stress responses at slaughter in sheep
Abstract The slaughter period is very complex and may represent different types of stress for the animal. The way and extent animals react to these stress factors depend on their individual emotionalExpand
Choice of attractive conditions by beef cattle in a Y-maze just after release from restraint : Effect of sheep
To provide useful information on how to moderate post-handling stress, Angus heifers (n = 157) were individually allowed to enter a choice area after 2 min of restraint in a crush and to chooseExpand

Abstract The first experiment investigated the learning abilities of different types of heifers and the capacity of familiar conspecifics to reduce their behavioural reactivity. Two groups of 12–15Expand
Effects of Androgen Treatment on Behavioral and Physiological Responses of Heifers to Fear-Eliciting Situations
TLDR
Longer androgen treatment reduces fearfulness in cattle, at least in some situations, and possible mechanisms by which testosterone influences fear-related behaviors are proposed. Expand
The effects of odors from stressed mice on conspecific behavior
TLDR
Four experiments correlate conspecific reactions to odors from stressed (foot shocked) BALB/cJ mice with the frequency of specific motor activities and taste avoidance and fail to produce conditioned taste aversion, suggesting a sensory specificity in the use of these odors. Expand

TLDR
Results fit the hypothesis that, in addition to visual cues, an olfactory cue (perhaps adrenal in origin) is released towards the end of a fight to signal submission. Expand

Corticotropin-releasing factor antagonist attenuates defensive-withdrawal behavior elicited by odors of stressed conspecifics.
TLDR
Results suggest that central injection of alpha-helical CRF(9-41) reduces the level of fear induced by odors associated with threat, and CRF receptors are implicated in mediating the species-typical display of defensive-withdrawal behavior. Expand
Hormonal responses accompanying fear and agitation in the squirrel monkey
TLDR
Earlier research indicated that social support was beneficial for reducing stress when squirrel monkeys were tested in larger groups in their home environment, and adrenal and gonadal secretion changed significantly during the first day after social relations were established. Expand
Rat's responses to blood and body odors of stressed and non-stressed conspecifics
TLDR
Responses to these odors depend upon the stressor applied to the odor producing rats, and it is concluded that Rats subjected to different stress conditions may change the quality or concentration of the odors they emit and thereby alter the responses of rats receiving the odor. Expand
Discrimination of odors from stressed rats by non-stressed rats
TLDR
Results show that whilst test subjects preferred the half containing odors from non-stressed rats, this preference was decreased by the presence of stress odors to an extent concordant with the level of stressor applied to the odor donors. Expand
