The "pet effect": physiological calming in the presence of canines
Contributor(s):: Wheeler, E. A., Faulkner, M. E.
The "pet effect," whereby interaction with a companion animal reduces the physiological indices of stress, varies with respect to fear of animals, companion animal guardianship, type of companion animal, or types of stress. In this study, a non-clinical sample of 223 undergraduates underwent the...
A trained demonstrator has a calming effect on naive horses when crossing a novel surface
Contributor(s):: Rorvang, M. V., Ahrendt, L. P., Christensen, J. W.
Habituated horses have been found to have a calming effect on conspecifics in fear-eliciting situations. In practice, experienced horses are often used as companions when young horses are introduced to potentially frightening situations, like loading onto a trailer. However, studies of social...
The influence of gentle interactions on avoidance distance towards humans, weight gain and physiological parameters in group-housed dairy calves
Contributor(s):: Lurzel, S., Munsch, C., Windschnurer, I., Futschik, A., Palme, R., Waiblinger, S.
The quality of the relationship between cattle and their caretakers is important for animal welfare and productivity. Nevertheless, the influence of gentle interactions on group-housed dairy calves has not been thoroughly studied so far. We examined the effects of 42 min of gentle interactions...
Exploring synchronicity in the heart rates of familiar and unfamiliar pairs of horses and humans undertaking an in-hand task
Contributor(s):: Hockenhull, J., Young, T. J., Redgate, S. E., Birke, L.
Physiological responses that occur in horses and humans during their interactions, on the ground and during ridden work, have been investigated in a number of studies with some conflicting results. These suggest that in some situations emotional state may be transferred from humans to horses and...
The psychological and physiological effects of using a therapy dog in mindfulness training
Contributor(s):: Henry, C. L., Crowley, S. L.
The present study was a randomized controlled trial examining the psychological and physiological effects of adding animal-assisted therapy (AAT) to a modified Mindfulness-Based Stress Reduction program (MBSR) for clients experiencing psychological distress. It was hypothesized that AAT would...
Does physical contact with a dog or person affect performance of a working memory task?
Contributor(s):: Gee, N. R., Friedmann, E., Coglitore, V., Fisk, A., Stendahl, M.
Working memory (WM) plays a critical role in the execution of a wide variety of cognitive tasks and predicts academic success. This study was designed to compare the impact of the presence of a dog or a person, and physical contact with them, on the performance of a WM task. It also examined...
Effects of gentle interactions on the relationship with humans and on stress-related parameters in group-housed calves
Contributor(s):: Lurzel, S., Windschnurer, I., Futschik, A., Palme, R., Waiblinger, S.
Although the relationship between farm animals and humans has strong implications for animal welfare and productivity, there have been few experimental studies on the influence of gentle interactions in group-housed calves. In the present study, Austrian Simmental calves were housed in groups of...

Are results of Crib Opening Test connected with efficacy of training horses in a round-pen?
Contributor(s):: Wilk, I., Kedzierski, W., Stachurska, A., Janczarek, I.
Training the horse is based on human-horse relationship, which requires that the horse shows active, conscious behaviour as well as an ability to learn. It was hypothesized that the horse's learning skill to open the crib is correlated with the effectiveness of training. The aim of the study was...
Measuring heart rate variability in horses to investigate the autonomic nervous system activity - pros and cons of different methods
Contributor(s):: Stucke, D., Ruse, M. G., Lebelt, D.
Power spectrum analysis of heart rate variability (HRV) may provide insight into the mental state of the animal held in restricted specific experimental conditions. Determining inter-beat-interval (IBI) variations is one way to measure changes in autonomic nervous system (ANS) activity in horses....
No increased stress response in horses on small and electrically fenced paddocks
Contributor(s):: Glauser, A., Burger, D., Dorland, H. A. van, Gygax, L., Bachmann, I., Howald, M., Bruckmaier, R. M.
Regular free movement is an important factor for the wellbeing of horses, reducing the risk of behavioural disorders as well as maintaining bodily functions healthy. Currently animal welfare legislations in several countries require minimal stay times in outdoor enclosures. However, clear legal...
Stress assessment in small ruminants kept on city farms in Southern Germany
Contributor(s):: Schilling, A. K., Reese, S., Palme, R., Erhard, M., Wohr, A. C.
Sheep and goats are frequently used in nonhuman animal-assisted activities on city farms. There are few data available on this type of usage of small ruminants. Health evaluations, behavioral observations (feeding, resting, comfort, explorative and social behaviors), behavioral tests (human...
The effects of a high-starch or high-fibre diet on equine reactivity and handling behaviour
Contributor(s):: Bulmer, L., McBride, S., Williams, K., Murray, J. A.
Increasing performance work in the horse is often associated with a reduction in the forage ration and an increase in concentrates, usually in the form of high-starch cereal grains. This type of diet has been associated with stereotypic behaviours and health problems. High-starch diets are also...

Effects of mother versus artificial rearing during the first 12 weeks of life on challenge responses of dairy cows
Contributor(s):: Wagner, K., Seitner, D., Barth, K., Palme, R., Futschik, A., Waiblinger, S.
We investigated the effects of mother versus artificial rearing on the responses to a social and a non-social challenge in adulthood. Rearing of treatment groups only differed during the first 12 weeks of life. Artificially reared animals were separated from their mothers within 24 h after birth...
Emotions in dogs being petted by a familiar or unfamiliar person: validating behavioural indicators of emotional states using heart rate variability
Contributor(s):: Kuhne, F., Hossler, J. C., Struwe, R.
Although physical human-dog interactions have an important influence on the human-dog relationship, few studies have proposed the key factors of physical human-dog contact affecting the well-being of dogs. Therefore, our aim was to investigate the effect of physical human-dog contact on the...

Contributor(s):: Bourguet, C., Deiss, V., Boissy, A., Terlouw, E. M. C.
The present study investigated relationships between reactivity during tests, stress reactions at slaughter and animal traits in young Blond d'Aquitaine (BA), Limousin (LI) and Angus (AN) bulls. Behavioural and physiological reactivity of animals was evaluated during rearing using a "Human test"...
The reinforcing value of physical contact and the effect on canine heart rate of grooming in different anatomical areas
Contributor(s):: McGreevy, P. D., Righetti, J., Thomson, P. C.
The human-animal relationship frequently involves physical touch, and this may have benefits for both participants. Grooming of horses at the withers has a calming effect on recipients, a phenomenon regularly used to reward horses. No studies on the effect on heart rate of grooming in different...
