Cortisol levels in dolphin Tursiops truncatus interactive programs linked to humanNiveles de cortisol en delfines Tursiops truncatus vinculados a programas interactivos con humanos
Contributor(s):: Sanchez Okrucky, R., Morales Vela, B.
Understanding the physiological changes in animals during physical activity to improve animal welfare has become increasingly important in animal collections that remain under human care. To date, the effect of interactive programs on dolphins under human care has not been evaluated, for that...
Positive and negative gestational handling influences placental traits and mother-offspring behavior in dairy goats
Contributor(s):: Baxter, E. M., Mulligan, J., Hall, S. A., Donbavand, J. E., Palme, R., Aldujaili, E., Zanella, A. J., Dwyer, C. M.
Dairy animals are subjected to a number of potential stressors throughout their lives, including daily interactions with humans. The quality of these interactions may have direct consequences for the animal undergoing the experience, but if such events occur during gestation it may also affect...
Impact of structural and cognitive enrichment on the learning performance, behavior and physiology of dwarf goats ( Capra aegagrus hircus)
Contributor(s):: Oesterwind, S., Nurnberg, G., Puppe, B., Langbein, J.
Intensive husbandry usually offers only limited opportunities for animals to perform their characteristic species-specific behavior and can lead to boredom, stress or frustration. The positive impact of structural forms of environmental enrichment on animal welfare is well investigated because it...
Environmentally enriching American mink ( Neovison vison) increases lymphoid organ weight and skeletal symmetry, and reveals differences between two sub-types of stereotypic behaviour
Contributor(s):: Diez-Leon, M., Bursian, S., Galicia, D., Napolitano, A., Palme, R., Mason, G.
Enrichment studies for wild carnivores (e.g., in zoos) are often short-term, use enrichments of unknown motivational significance, and focus on glucocorticoids and stereotypic behaviour (SB), ignoring other stress-relevant variables. Our study assessed the broad behavioural and physiological...
Effects of visual contact with zoo visitors on black-capped capuchin welfare
Contributor(s):: Sherwen, S. L., Harvey, T. J., Magrath, M. J. L., Butler, K. L., Fanson, K. V., Hemsworth, P. H.
Previous research has suggested that the presence of zoo visitors may be stressful for various primate species, and visual contact with visitors may be the sensory stimuli that mediate visitor effects. We studied a group of black-capped capuchins, Cebus apella, in a controlled experiment,...
The effects of witnessing managemental procedures during the light versus the dark phase of the light cycle on behaviour, performance and welfare of laboratory rats
Contributor(s):: Abou-Ismail, U. A., Mohamed, R. A., El-Kholya, S. Z.
Research has indicated that witnessing managemental procedures are stressful to laboratory rats. Yet there has been little investigation into whether the time of witnessing these procedures affects behaviour and welfare in these animals. Ninety-six rats, representing two batches, were used in...
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...
How animals respond to change

Sections on underpinning principles relating to stress in companion animals, the effects of presistent stress, or "Why Stress can be so Stressful", other considerations for assessing welfare, and stress auditing.
Heart rate variability during a working memory task: does touching a dog or person affect the response?
Contributor(s):: Gee, N. R., Friedmann, E., Stendahl, M., Fisk, A., Coglitore, V.
The presence of a dog has been associated with reduced responses to stressors in several, but not all, previous studies. The presence of a dog has also been related to improved performance on some cognitive tasks. The current study was designed to evaluate the effect of touching a dog on stress...
A combination of behavioral and physiological indicators for assessing pig welfare on the farm
Contributor(s):: Candiani, D., Salamano, G., Mellia, E., Doglione, L., Bruno, R., Toussaint, M., Gruys, E.
The purpose of this research was to identify pig welfare indicators that could help in recognizing stressful practices on farm. The study evaluated behavioral and physiological indicators (cortisol and negative acute phase proteins) in 2 groups of 20 female pigs 4 months old after a 48-hr...
A multidisciplinary approach to assess the welfare of weaned pigs during transport at three space allowances
Contributor(s):: Sutherland, M. A., Bryer, P. J., Davis, B. L., McGlone, J. J.
Transport can be a stressful experience for pigs, especially in pigs simultaneously experiencing weaning stress. The objective of this study was to use a multidisciplinary approach to assess the welfare of weaned pigs during transport at 3 space allowances. A commercial semitrailer, fitted with...
A nonnatural head-neck position ( Rollkur ) during training results in less acute stress in elite, trained, dressage horses
Contributor(s):: Breda, E. van
This study measured parameters of stress in recreational, trained horses (REC; n=7) and elite (International Grand Prix level) trained, dressage horses (DRES; n=5). The training of the DRES horses uses an unnatural head-neck position (Rollkur), whereas in the REC horses such training techniques...
Development and validation of a behavioral acclimation protocol for cats to respiration chambers used for indirect calorimetry studies
Contributor(s):: Gooding, M. A., Duncan, I. J. H., Atkinson, J. L., Shoveller, A. K.
Cats exposed to novel environments initiate stress responses by behavioral and physiological changes that modify metabolism and lead to the collection of unreliable data. Fourteen cats (10+or-2 months) were subjected to an 11-week acclimation procedure to adapt to restriction within chambers used...
Effects of training on stress-related behavior of the common marmoset ( Callithrix jacchus ) in relation to coping with routine husbandry procedures. (Training Nonhuman Primates Using Positive Reinforcement Techniques)
Contributor(s):: Bassett, L., Buchanan-Smith, H. M., McKinley, J., Smith, T. E.
Using positive reinforcement, 12 common marmosets (Callithrix jacchus) were trained to provide urine samples on request. The marmosets were exposed to mildly stressful, routine husbandry procedures (i.e., capture and weighing). The non-human animals spent less time inactive poststressor as...
Noise in the animal shelter environment: building design and the effects of daily noise exposure
Contributor(s):: Coppola, C. L., Enns, R. M., Grandin, T.
Sound levels in animal shelters regularly exceed 100 dB. Noise is a physical stressor on animals that can lead to behavioral, physiological, and anatomical responses. There are currently no policies regulating noise levels in dog kennels. The objective of this study was to evaluate the noise...
Physiological arousal for companion dogs working with their owners in animal-assisted activities and animal-assisted therapy
Contributor(s):: Haubenhofer, D. K., Kirchengast, S.
This study investigated the physiological reactions of companion dogs (Canis familiaris) used in animal-assisted activities and animal-assisted therapy by measuring salivary cortisol concentrations. The dog caregivers (owners) collected saliva samples (a) at 3 control days without therapeutic...
