Influence of handler relationships and experience on health parameters, glucocorticoid responses and behaviour of semi-captive Asian elephants
| Contributor(s):: Crawley, J. A. H., Liehrmann, O., Franco Dos Santos, D. J., Brown, J., Nyein, U. K., Aung, H. H., Htut, W., Oo, Z. M., Seltmann, M. W., Webb, J. L., Lahdenperä, M., Lummaa, V.
Declining wild populations combined with accumulating captive populations of e.g. livestock, pets, draught and zoo animals have resulted in some threatened species with substantial proportions of their populations in captivity. The interactions animals have with humans in captivity depend on...

Effect of Cage Type on Fecal Corticosterone Concentration in Buck Rabbits During the Reproductive Cycle
| Contributor(s):: Cornale, Paolo, Macchi, Elisabetta, Renna, Manuela, Prola, Liviana, Perona, Giovanni, Mimosi, Antonio
Fecal corticosterone concentration (FCC) was measured in 14 buck rabbits individually housed in standard-dimension cages (SC) or in bigger cages (BC; with a volume more than double that of SC and equipped with a plastic foot mat) during 4 consecutive reproductive cycles. Cage type and...
Weaning and separation stress: maternal motivation decreases with litter age and litter size in farmed mink
| Contributor(s):: Malmkvist, Jens, Sørensen, Dennis D., Larsen, Torben, Palme, Rupert, Hansen, Steffen W.
The optimal timing of separating the mink dam from the litter is suggested to be a balance between the partly conflicting needs of the mother and the kits. Early removal of the dam or partial removal of the litter may protect the dam against exhaustion. Little is, however, known about dam stress...
Effects of Sheltering on Behavior and Fecal Corticosterone Level of Elderly Dogs
| Contributor(s):: Katsuji Uetake, Chu Han Yang, Aki Endo, Toshio Tanaka
In Japan, the human population is aging rapidly, and the abandonment of dogs by the elderly people who have died or been hospitalized becomes a problem. It is hypothesized that elderly dogs have difficulty adapting to the novel circumstances when brought to an animal shelter. Therefore, the...
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...
Program animal welfare: using behavioral and physiological measures to assess the well-being of animals used for education programs in zoos
| Contributor(s):: Baird, Bonnie A., Kuhar, Christopher W., Lukas, Kristen E., Amendolagine, Laura A., Fuller, Grace A., Nemet, James, Willis, Mark A., Schook, Mandi W.
This study investigates program animal welfare using both behavioral and physiological measures in two separate experiments. In Experiment One, we examined possible differences in behavior and fecal glucocorticoid metabolites (FGM) between education, exhibit and off-exhibit armadillos ( N=59)...
Hormonal and behavioural stress responses to capture and radio-collar fitting in free-ranging pampas deer ( Ozotoceros bezoarticus)
| Contributor(s):: Munerato, M. S., Marques, J. A., Caulkettt, N. A., Tomas, W. M., Zanetti, E. S., Trovati, R. G., Pereira, G. T., Palme, R.
This study evaluated the short-term hormonal and behavioural responses to capture and radio-collar fitting in free-ranging pampas deer ( Ozotoceros bezoarticus). Twenty adult deer (eleven females and nine males) were captured in the South Pantanal wetland (Brazil) and equipped with VHF...
The effects of social interaction and environmental enrichment on the space use, behaviour and stress of owned housecats facing a novel environment
| Contributor(s):: Rehnberg, L. K., Robert, K. A., Watson, S. J., Peters, R. A.
Every day, millions of domestic cats are held temporarily in captive environments, such as boarding catteries and rescue shelters. Being in confinement can potentially invoke high levels of stress for these animals. Therefore, there is a need to develop appropriate strategies to reduce these...
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,...
Events around weaning in semi-feral and stable-reared Konik polski foals: evaluation of short-term physiological and behavioural responses
| Contributor(s):: Gorecka-Bruzda, A., Suwala, M., Palme, R., Jaworski, Z., Jastrzebska, E., Boron, M., Jezierski, T.
The annual weaning, stabling and subsequent sale of semi-feral Konik polski foals born in forest reserves ensure a stable population of free-roaming Konik polski horses. However, welfare concerns regarding the maternal and herd separation of young horses, manipulation by humans, transportation...
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...
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...
Effect of work experience and position in the plow harness on some physiological parameters of horses under field conditions
| Contributor(s):: Aguirre, V., Orihuela, A.
Six pairs of horses were studied during 6 consecutive days. One horse in each pair had working experience. The position of the 2 animals in the plough harness was alternated each day. Some physical and physiological parameters were measured at different stages during each work day. A split-plot...
Fecal concentrations of cortisol, testosterone, and progesterone in cotton-top tamarins housed in different zoological parks: relationships among physiological data, environmental conditions, and behavioral patterns
| Contributor(s):: Fontani, S., Vaglio, S., Beghelli, V., Mattioli, M., Bacci, S., Accorsi, P. A.
The aim of this investigation was to study the welfare of 3 captive groups of cotton-top tamarins housed in different zoological parks. Ethological observations were conducted during 1 year. In addition, fecal samples were collected and the concentrations of glucocorticoids, androgens, and...
Frustrated appetitive foraging behavior, stereotypic pacing, and fecal glucocorticoid levels in snow leopards ( Uncia uncia ) in the Zurich Zoo
| Contributor(s):: Burgener, N., Gusset, M., Schmid, H.
This study hypothesized that permanently frustrated, appetitive-foraging behavior caused the stereotypic pacing regularly observed in captive carnivores. Using 2 adult female snow leopards (U), solitarily housed in the Zurich Zoo, the study tested this hypothesis experimentally with a novel...
Using fecal hormonal and behavioral analyses to evaluate the introduction of two sable antelope at Lincoln Park Zoo
| Contributor(s):: Loeding, E., Thomas, J., Bernier, D., Santymire, R.
Introductions of sable antelope (Hippotragus niger) can be difficult due to the potential ensuing aggression compounded by their large horns. The goal was to use hormonal assays and behavioral analyses to evaluate the success of an introduction of 2 adult females at Lincoln Park Zoo. The...
