Oxytocin and Cortisol Levels in Dog Owners and Their Dogs Are Associated with Behavioral Patterns: An Exploratory Study
| Contributor(s):: Maria Petersson, Kerstin Uvnäs-Moberg, Anne Nilsson, Lise-Lotte Gustafson, Eva Hydbring-Sandberg, Linda Handlin
We have previously shown that dog–owner interaction results in increasing oxytocin levels in owners and dogs, decreasing cortisol levels in owners but increasing cortisol levels in dogs. The present study aimed to further investigate whether oxytocin and cortisol levels in the previously...
Cortisol and Secretory Immunoglobulin A Response to Stress in German Shepherd Dogs
| Contributor(s):: Ivona Svobodová, Helena Chaloupková, Roman Koncel, Luděk Bartoš, Lenka Hradecká, Lukáš Jebavý
The aim of the study was to determine whether cortisol and secretory Immunoglobulin A (sIgA) could be used as an indicator of acute stress in both young and adult dogs. Seventeen German shepherd puppies were exposed to the Puppy test (challenge test) at the age of seven weeks. This test has...
Training Reduces Stress in Human-Socialised Wolves to the Same Degree as in Dogs
| Contributor(s):: Angélica da Silva Vasconcellos, Zsófia Virányi, Friederike Range, César Ades, Jördis Kristin Scheidegger, Erich Möstl, Kurt Kotrschal
The welfare of animals in captivity is of considerable societal concern. A major source of stress, especially for wild animals, is the lack of control over their environment, which includes not being able to avoid contact with human beings. Paradoxically, some studies have shown that...
Evaluation of effects of olfactory and auditory stimulation on separation anxiety by salivary cortisol measurement in dogs
| Contributor(s):: Yoon-Joo Shin, Nam-Shik Shin
Separation anxiety (SA) is a serious behavioral problem in dogs. In this study, salivary cortisol was studied to determine if the owner's odor or voice could reduce SA in dogs. Twenty-eight dogs with SA were divided into three groups: group 1 (control), group 2 (with owner's clothes...
The effect of a service dog on salivary cortisol awakening response in a military population with posttraumatic stress disorder (PTSD)

The Effectiveness Of Enrichment Programs For Dogs In An Animal Shelter
| Contributor(s):: Pamela Perry
Dogs (N = 108) in an animal shelter received one of four enrichment programs: twice daily walking alone (walking) or in combination with a daily fooddispensing toy (toy), a daily session of standardized human contact (petting), or daily obedience training (obedience). We evaluated the effects of...
Human interaction and cortisol: Can human contact reduce stress for shelter dogs?

A case study: fecal corticosteroid and behavior as indicators of welfare during relocation of an Asian elephant
| Contributor(s):: Laws, N., Ganswindt, A., Heistermann, M., Harris, M., Harris, S., Sherwin, C.
This study was a preliminary investigation of an enzyme immunoassay for measuring fecal glucocorticoid metabolites in a male Asian elephant (Elephas maximus) by investigating changes in behavior and cortisol metabolite excretion associated with a putative stressful event. The study collected...
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...
Behavioral and hormonal consequences of transporting giant pandas from China to the United States
| Contributor(s):: Snyder, R. J., Perdue, B. M., Powell, D. M., Forthman, D. L., Bloomsmith, M. A., Maple, T. L.
Zoological institutions strive to ensure the welfare of nonhuman animals in captivity. Part of this effort involves reducing the level of distress experienced by an animal to the greatest extent possible. However, some necessary zoo management practices such as transportation induce stress...
Circadian rhythm of salivary cortisol in Asian elephants (Elephas maximus): a factor to consider during welfare assessment
| Contributor(s):: Menargues, A., Urios, V., Liminana, R., Mauri, M.
Elevated glucocorticoid levels during an extended time period might be a stress indicator in nonhuman animals. Therefore, knowledge of the circadian pattern of cortisol secretion is very important to correctly interpret data obtained for welfare assessment of animals in captivity through salivary...
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...
Impact of zoo visitors on the fecal cortisol levels and behavior of an endangered species: Indian blackbuck ( Antelope cervicapra L.)
| Contributor(s):: Thangavel, Rajagopal, Govindaraju, Archunan, Mahadevan, Sekar
This study investigated behavioral activities (resting, moving, aggressive, social, and reproductive behavior) and fecal cortisol levels in 8 individually identified adult male blackbucks during periods of varying levels of zoo visitors (zero, low, high, and extremely high zoo visitor density)....
Minimal number of conspecifics needed to minimize the stress response of isolated mature ewes
| Contributor(s):: Carbajal, S., Orihuela, A.
The objective of this study was to determine the minimum number of conspecifics that sheep require to minimize the stress associated with isolation from the flock. The study used twelve 3-year-old Suffolk ewes. Every test day, the study randomly selected 1, 2 or 3 ewes to be visually separated...
