Canine Detection of the Volatilome: A Review of Implications for Pathogen and Disease Detection
Contributor(s):: Craig Angle, Lowell Paul Waggoner, Arny Ferrando, Pamela Haney, Thomas Passler
The volatilome is the entire set of volatile organic compounds (VOC) produced by an organism. The accumulation of VOC inside and outside of the body reflects the unique metabolic state of an organism. Scientists are developing technologies to non-invasively detect VOC for the purposes of medical...
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...
Effect of pet insects on the psychological health of community-dwelling elderly people: a single-blinded, randomized, controlled trial
Contributor(s):: Ko, H. J., Youn, C. H., Kim, S. H., Kim, S. Y.
Background: There is evidence that animal-assisted therapy has positive effects on mental health, especially in elderly people. Caring for insects is easy, relatively inexpensive, and does not require much space. Objective: The aim of this 8-week randomized, controlled, single-blinded study was...
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...
Hunger in pregnant sows: effects of a fibrous diet and free access to straw
Contributor(s):: Jensen, M. B., Pedersen, L. J., Theil, P. K., Knudsen, K. E. B.
Fibrous diets and the provision of straw have been suggested to reduce feeding motivation in pregnant sows. The present experiment investigated the separate and interactive effects of a fibrous diet and ad libitum access to straw on feeding motivation, oral behaviour and plasma levels of...
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...
Early transfer of mated females into the maternity unit reduces stress and increases maternal care in farm mink
Contributor(s):: Malmkvist, J., Palme, R.
Mated mammals on farms are typically transferred to another housing environment prior to delivery. We investigated whether the timing of this transfer - EARLY (Day -36), INTERMEDIATE (Day -18), or LATE (Day -3) relative to the expected day of birth (Day 0) - affects maternal stress, maternal care...
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,...
Head partitions at the feed barrier affect behaviour of goats
Contributor(s):: Nordmann, E., Barth, K., Futschik, A., Palme, R., Waiblinger, S.
Space allowance at the feeding places often forces goats to feed in close proximity, that is, less than their individual distances. In consequence, agonistic behaviour may increase as well as stress and injuries, while access to feed may decrease, especially in low-ranking goats. Partitions...
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...
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...
Gut microbiota of humans, dogs and cats: current knowledge and future opportunities and challenges
Contributor(s):: Deng, P., Swanson, K. S.
High-throughput DNA sequencing techniques allow for the identification and characterisation of microbes and their genes (microbiome). Using these new techniques, microbial populations in several niches of the human body, including the oral and nasal cavities, skin, urogenital tract and...
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...
