  1. 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...

  2. Acoustic analysis of cattle ( Bos taurus) mother-offspring contact calls from a source-filter theory perspective

    Contributor(s):: Torre, M. P. de la, Briefer, E. F., Reader, T., McElligott, A. G.

    Cattle vocalisations have been proposed as potential indicators of animal welfare. However, very few studies have investigated the acoustic structure and information encoded in these vocalisations using advanced analysis techniques. Vocalisations play key roles in a wide range of communication...

  3. Well-being and its roots

    Contributor(s):: Fraser, A. F.

    This chapter describes the physiological and behavioural indicators of health and well-being in cats. The specific behavioural traits of some different cat breeds are also included.

  4. Travel-related problems in pets

    Contributor(s):: Mills, D., Dube, M. B., Zulch, H.

    Sections on the nature and treatment of travel-related problems of pets, including cats.

  5. 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...

  6. The prevalence and implications of human-animal co-sleeping in an Australian sample

    Contributor(s):: Smith, B., Thompson, K., Clarkson, L., Dawson, D.

    Sleep research is characterized by an interest in humans, with the realm of animal sleep left largely to ethologists and animal scientists. However, the lives of sleep-study participants and those with sleep problems frequently involve animals. For the majority of the population in developed...

  7. Facilitating 'learning from mom how to eat like a pig' to improve welfare of piglets around weaning

    Contributor(s):: Oostindjer, M., Kemp, B., Brand, H. van den, Bolhuis, J. E.

    Piglets in commercial husbandry are weaned abruptly and at a rather young age. Many weanling piglets are poorly adapted to ingest solid food, often resulting in a period of underfeeding. The underfeeding generally leads to a poor growth, diarrhoea occurrence and the development of damaging...

  8. Scent of the familiar: an fMRI study of canine brain responses to familiar and unfamiliar human and dog odors

    Full-text: Available

    | Contributor(s):: Berns, G. S., Brooks, A. M., Spivak, M.

    Understanding dogs' perceptual experience of both conspecifics and humans is important to understand how dogs evolved and the nature of their relationships with humans and other dogs. Olfaction is believed to be dogs' most powerful and perhaps important sense and an obvious place to begin...

  9. Why do adult dogs 'play'?

    | Contributor(s):: Bradshaw, J. W. S., Pullen, A. J., Rooney, N. J.

    Among the Carnivora, play behaviour is usually made up of motor patterns characteristic of predatory, agonistic and courtship behaviour. Domestic dogs are unusual in that play is routinely performed by adults, both socially, with conspecifics and with humans, and also asocially, with objects....

  10. Dogs and their human companions: the effect of familiarity on dog-human interactions

    | Contributor(s):: Kerepesi, A., Doka, A., Miklosi, A.

    There are few quantitative examinations of the extent to which dogs discriminate between familiar and unfamiliar persons. In our study we have investigated whether dogs show differential behaviour towards humans of different degrees of familiarity (owner, familiar person, unfamiliar person). Dogs...

  11. A comparison of pet and purpose-bred research dog ( Canis familiaris) performance on human-guided object-choice tasks

    | Contributor(s):: Lazarowski, L., Dorman, D. C.

    Several studies have shown that domestic dogs respond to human social cues such as pointing. Some experiments have shown that pet dogs outperformed wolves in following a momentary distal point. These findings have lent support to the hypothesis that domestication is responsible for domestic dogs'...

  12. Physiological effects of human-animal positive interaction in dogs - review of the literature

    | Contributor(s):: Pop, D., Rusu, A. S., Pop-Vancia, V., Papuc, I., Constantinescu, R., Miresan, V.

    Positive human-animal interactions (HAI) are known to increase the quality of life in both humans and dogs. Although there are several reviews on the benefits of HAI in humans, there are no reviews on the effects of positive HAI in dogs. Therefore, the aim of this paper is to provide a review of...

  13. Canine scent detection of human cancers: a review of methods and accuracy

    | Contributor(s):: Moser, E., McCulloch, M.

  14. Octopus senescence: the beginning of the end

    | Contributor(s):: Anderson, R. C., Wood, J. B., Byrne, R. A.

    Senescence is a normal stage of an octopus's life cycle that often occurs before death. Some of the following symptoms typify it: lack of feeding, retraction of skin around the eyes, uncoordinated movement, increased undirected activity, and white unhealing lesions on the body. There is inter-...

  15. Absence of effects from immunocontraception on seasonal birth patterns and foal survival among barrier island wild horses

    | Contributor(s):: Kirkpatrick, J. F., Turner, A.

    Despite a large body of safety data, concern exists that porcine zonae pellucidae (PZP) immunocontraception - used to manage wild horse populations - may cause out-of-season births with resulting foal mortality. Our study at Assateague, Maryland indicated the effects of immunocontraception on...

  16. There's a rat in my room! Now what? Mice show no chronic physiological response to the presence of rats

    | Contributor(s):: Meijer, M. K., Loo, P. L. P. van, Baumans, V.

    In general, guidelines on housing and care of animals in the laboratory state that rats and mice should not be housed in the same room. Mice may perceive rats as predators. Although one theory says this can cause stress, there is little scientific evidence to support this theory. In the wild,...

  17. Captive coyotes compared to their counterparts in the wild: does environmental enrichment help?

    | Contributor(s):: Shivik, J. A., Palmer, G. L., Gese, E. M., Osthaus, B.

    This article attempts to determine the effects of environment (captive or wild) and a simple form of environmental enrichment on the behavior and physiology of a nonhuman animal. Specifically, analyses first compared behavioral budgets and stereotypic behavior of captive coyotes (Canis latrans)...

  18. Effect of gestation management system on gilt and piglet performance

    | Contributor(s):: Muns, R., Manzanilla, E. G., Manteca, X., Gasa, J.

    Individual gestation housing of pregnant sows in stalls from four weeks after mating is banned in the EU. Two experiments were conducted to study the effect of two gestation management and housing systems (STALL: gilts housed in stalls and PEN: gilts loose-housed in pens with increased feed...

  19. Randomized trial examines effects of equine facilitated learning on adolescents' basal cortisol levels

    | Contributor(s):: Pendry, P., Smith, A. N., Roeter, S. M.

    Although equine facilitated programs have gained in popularity over the last decade, virtually nothing is known about the causal effects of equine facilitated interventions on human development and well-being. Researchers conducted a randomized trial to determine the effects of an 11-week equine...

  20. Pet ownership, other domestic relationships, and satisfaction with life among seniors: results from a Canadian National Survey
