  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. 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.

  4. 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.

  5. 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...

  6. 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...

  7. 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)...

  8. 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,...

  9. 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...

  10. 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...

  11. Number of nearby visitors and noise level affect vigilance in captive koalas

    Contributor(s):: Larsen, M. J., Sherwen, S. L., Rault, J. L.

    Understanding human-animal interactions is particularly important for institutions that display animals to the public due to the frequent, and sometimes intense, interactions with unfamiliar humans. Past research has shown that visitors can have a negative impact on the welfare of a wide range of...

  12. Welfare of farmed musk deer: changes in the biological characteristics of musk deer in farming environments

    Contributor(s):: He, Lan, Li, LinHai, Wang, WenXia, Liu, Gang, Liu, ShuQiang, Liu, WenHua, Hu, DeFu

    Musk deer are an important economic wildlife resource, and long-term over-use has resulted in a sharp population decrease in the wild. Farming of musk deer is important to prevent the shrinking wild population from being hunted for their musk. Musk deer farming has a history of more than 60 years...

  13. Zoo visitor effect on mammal behaviour: does noise matter?

    Contributor(s):: Quadros, S., Goulart, V. D. L., Passos, L., Vecci, M. A. M., Young, R. J.

    The zoo visitor effect is the change in animal behaviour and physiology in response to the presence of a viewing public. It is thought to result from, amongst other things, visitor generated sound (i.e., noise), but this hypothesis has never been explicitly tested. We tested this hypothesis...

  14. Providing elevated 'getaway bunks' to nursing mink dams improves their health and welfare

    Contributor(s):: Dawson, L., Buob, M., Haley, D., Miller, S., Stryker, J., Quinton, M., Mason, G.

  15. Environmental enrichment exerts anxiolytic effects in the Indian field mouse (Mus booduga)

    Contributor(s):: Varman, D. R., Ganapathy, Marimuthu, Rajan, K. E.

  16. Effects of varying feed provision on behavioral patterns of farmed collared peccary (Mammalia, Tayassuidae)

    Contributor(s):: Nogueira, S. S. C., Calazans, S. G., Costa, T. S. O., Peregrino, H., Nogueira-Filho, S. L. G.

    Feeding enrichment regime has been widely employed as an important tool to mimic foraging behavior and improve farm animals' welfare. Some authors have argued that creating some level of uncertainty in the animals' environment is beneficial. Therefore, we evaluated the effects of challenge...

  17. Review of wallowing in pigs: description of the behaviour and its motivational basis

    Contributor(s):: Bracke, M. B. M.

    Wallowing, i.e. coating the body surface with mud, is a natural behaviour of pigs, commonly observed in feral pigs and wild boar, but rarely provided for in current housing systems for domestic pigs. Furthermore, in welfare science the subject has not been receiving much attention. This paper...

  18. Stress response of working African elephants to transportation and safari adventures

    Contributor(s):: Millspaugh, T. T., Burke, T., Dyk, G. van, Slotow, R., Washburn, B. E., Woods, R. J.

    African elephants (Loxodonta africana) are intensively managed in southern Africa and are routinely translocated between reserves. Domesticated elephants are used for elephant-back safaris and interactions with guests. Understanding how elephants respond to such activities is critical because of...

  19. Adrenocorticotrophin-induced stress response in captive vicunas ( Vicugna vicugna ) in the Andes of Chile

    Contributor(s):: Bonacic, C., Macdonald, D. W., Villouta, G.

    The vicuna is mainly used in two ways: wild captured, shorn and returned to the wild; or wild captured and maintained in captivity as part of a programme of sustainable use in the Andes of South America. Farming of wild vicunas has hitherto involved no assessment of their welfare. In this study a...

  20. Body weight change as a measure of stress: a practical test

    Contributor(s):: McLaren, G. W., Mathews, F., Fell, R., Gelling, M., Macdonald, D. W.

    We report on the efficacy of body weight change as a measure of trapping and handling stress in two species of wild small mammal: bank voles (Clethrionomys glareolus) and wood mice (Apodemus sylvaticus). We tested two hypotheses: (1) that weight change after capture and handling is related to the...
