  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. Effect of pre-partum habituation to milking routine on behaviour and lactation performance of buffalo heifers

    Contributor(s):: Polikarpus, A., Napolitano, F., Grasso, F., Palo, R. di, Zicarelli, F., Arney, D., Rosa, G. de

    The aim of this study was to investigate the effect pre-partum habituation in the milking parlour on behaviour and lactation performance of buffalo heifers. Sixteen buffalo heifers in late gestation were used for this study. The animals, with an age ranging from 30 to 44 months at the start of...

  4. Emotions in dogs being petted by a familiar or unfamiliar person: validating behavioural indicators of emotional states using heart rate variability

    Contributor(s):: Kuhne, F., Hossler, J. C., Struwe, R.

    Although physical human-dog interactions have an important influence on the human-dog relationship, few studies have proposed the key factors of physical human-dog contact affecting the well-being of dogs. Therefore, our aim was to investigate the effect of physical human-dog contact on the...

  5. 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.

  6. 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.

  7. 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'...

  8. 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...

  9. 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...

  10. 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...

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

    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 for the...

  12. 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...

  13. 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....

  14. 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...

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

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

  16. 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...

  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. 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,...

  19. Behavior of feral horses in response to culling and GnRH immunocontraception

    Contributor(s):: Ransom, J. I., Powers, J. G., Garbe, H. M., Oehler, M. W., Sr., Nett, T. M., Baker, D. L.

    Wildlife management actions can alter fundamental behaviors of individuals and groups, which may directly impact their life history parameters in unforeseen ways. This is especially true for highly social animals because changes in one individual's behavior can cascade throughout its social...

  20. Bite marks in mink-induced experimentally and as reflection of aggressive encounters between mink

    Contributor(s):: Hansen, S. W., Moller, S. H., Damgaard, B. M.

    For many years, bite marks have been used as an indicator for aggression in mink production systems. However, the validity of bite marks as indicator of aggression has recently been questioned. We therefore tested the following hypotheses: (1) experimentally applied pressure to, or penetration...
