  1. Environmental enrichment for dendrobatid frogs

    Contributor(s):: Hurme, K., Gonzalez, K., Halvorsen, M., Foster, B., Moore, D., Chepko-Sade, B. D.

    The Central Park Zoo, one of the Wildlife Conservation Society's Living Institutions in New York, recently renovated an exhibit for dart-poison frogs. Staff developed a new hollow coconut insect feeder in conjunction with this project. When the exhibit change, coconut feeder, and other...

  2. Nutritional and behavioral effects of gorge and fast feeding in captive lions

    Contributor(s):: Altman, J. D., Gross, K. L., Lowry, S. R.

    Nonhuman animals in captivity manifest behaviors and physiological conditions that are not common in the wild. Lions in captivity face problems of obesity, inactivity, and stereotypy. To mediate common problems of captive lions, this study implemented a gorge and fast feeding schedule that better...

  3. Oral behaviors of beef steers in pen and pasture environments

    Contributor(s):: Ishiwata, T., Uetake, K., Kilgour, R. J., Eguchi, Y., Tanaka, T.

    This study observed the behavioral characteristics of 122 steers in eight pens and 1,136 steers at six pastures. Nonhuman animals kept in pens performed less nutritive oral behaviors and more nonnutritive oral behaviors than animals kept at pasture. Although these could not be described as...

  4. Spectral analysis of feeding and lying behavior of cattle kept under different feedlot conditions

    Contributor(s):: Wilson, S. C., Dobos, R. C., Fell, L. R.

    This study used spectral analysis in 2 separate experiments to examine feeding and lying behavior of Bos taurus steers under 2 housing treatments: a feedlot yard stocked at 12.0 m2 per head with a dry, firm pen surface (NDF) and a "high density" (HDF) feedlot yard stocked at 6.0 m2 per head with...

  5. My owner, right or wrong: the effect of familiarity on the domestic dog's behavior in a food-choice task

    Contributor(s):: Cook, A., Arter, J., Jacobs, L. F.

    Dogs are strongly influenced by human behavior, and they readily form bonds with specific humans. Yet these lines of inquiry are not often combined. The goal of this study was to investigate whether such bonds would play a role in how dogs behave in response to human signals. Using various types...

  6. What is the relationship between level of infection and 'sickness behaviour' in cattle?

    Contributor(s):: Szyszka, O., Kyriazakis, I.

  7. Behavioral ecology of savanna chimpanzees (Pan troglodytes verus) with respect to insectivory at Fongoli, Senegal

    Contributor(s):: Stephanie Lynn Bogart, Jill D. Pruetz (adviser)

    In this dissertation I examine the behavioral ecology of savanna chimpanzees in Senegal. I test hypotheses related to the effects of the environment on the diet of the chimpanzees at Fongoli, concentrating on their insectivory specifically. Fongoli is the hottest and driest site in which...

  8. Feeding Chromonaela odorata during pregnancy to goat dams affects acceptance of this feedstuff by their offspring

    Contributor(s):: Phan Vu, Hai, Everts, H., Dam Van, Tien, Schonewille, J. T., Hendriks, W. H.

  9. Veganism and living well

    Contributor(s):: Ciocchetti, C.

  10. Is the domestic dog (Canis familiaris) a reservoir host of American cutaneous leishmaniasis? A critical review of the current evidence

    Contributor(s):: Reithinger, R., Davies, C. R.

  11. Food health policies and ethics: lay perspectives on functional foods. (Special issue: Ethics as a dimension of agrifood policy: selected papers from the 4th Congress of the European Society for Agricultural and Food Ethics)

    Contributor(s):: Holm, L.

    Functional foods are a challenge to food health policies, since they question central ideas in the way that food health policies have been developed over the last decades. Driven by market actors instead of public authorities and focusing on the role of single foods and single constituents in...

  12. Vegetarian meat: could technology save animals and satisfy meat eaters?

    Contributor(s):: Hopkins, P. D., Dacey, A.

    Between people who unabashedly support eating meat and those who adopt moral vegetarianism, lie a number of people who are uncomfortably carnivorous and vaguely wish they could be vegetarians. Opposing animal suffering in principle, they can ignore it in practice, relying on the visual disconnect...

  13. Disambiguating the "guilty look": salient prompts to a familiar dog behaviour

    Contributor(s):: Horowitz, A.

  14. A general reaction pattern across situations in prepubertal gilts

    Contributor(s):: Thodberg, K., Jensen, K. H., Herskin, M. S.

    56 prepubertal crossbred Landrace/Yorkshire gilts were subjected to a Food Competition Test, an Open Field Test, a Human Test and a Social Test. The undisturbed behaviour was video recorded in the home pen before the tests were performed. Factor analysis on open field data identified 5 factors,...

  15. Alternative housing for sows and litters. Part 3. Effects of piglet diet quality and sow-controlled housing on performance and behaviour

    Contributor(s):: Pajor, E. A., Weary, D. M., Caceres, C., Fraser, D., Kramer, D. L.

    We studied how "sow-controlled" housing (i.e. housing where sows can leave their piglets at will) affects the behaviour and performance of sows and litters when tested under near-commercial conditions and with two different levels of piglet diet quality. Sows and litters were housed in pens where...

  16. Alternative housing for sows and litters. Part 4. Effects of sow-controlled housing combined with a communal piglet area on pre- and post-weaning behaviour and performance

    Contributor(s):: Weary, D. M., Pajor, E. A., Bonenfant, M., Fraser, D., Kramer, D. L.

    Previous experimental work has shown modest and variable production and welfare benefits for the lactating sow and piglets when sows are allowed to separate themselves temporarily from their piglets, or when piglets have access to a communal creep area sufficiently attractive that they spend...

  17. An automatic system to record foraging behaviour in free-ranging ruminants

    Contributor(s):: Rutter, S. M., Champion, R. A., Penning, P. D.

    Precise measurements of grazing behaviour are required to develop an understanding of the factors affecting the foraging behaviour of free-ranging domestic ruminants. An automatic, microcomputer-based system for the digital recording of the jaw movements of free-ranging cattle and sheep is...

  18. Applied animal behaviour science. (Special issue: Suckling)

    Contributor(s):: Lidfors, L., Svennersten-Sjaunja, K., Redbo, I.

    This supplement contains articles that focus on behavioural and physiological aspects of suckling and/or sucking in ruminants. Abnormal sucking behaviour, particularly cross-sucking and non-nutritive sucking, in calves are presented; and the effects of milk flow and milk volume, the presence of a...

  19. Behaviour of calves at introduction to nurse cows after the colostrum period

    Contributor(s):: Vaarst, M., Jensen, M. B., Sandager, A. M.

    In traditional housing systems for dairy herds, calves are very often placed in single boxes and fed milk from a bucket, which may lead to abnormal behaviour. In organic herds, for whom the aim is optimal animal welfare, there is interest in using suckling systems, where the calves have the...

  20. Behavioural, endocrine and immune consequences of mixing in weaned piglets

    Contributor(s):: Merlot, E., Meunier-Salaun, M. C., Prunier, A.

    Mixing piglets at weaning increases plasma cortisol concentrations and agonistic behaviour. In contrast to what is observed in older pigs, studies failed to show any effect of social environment on other behavioural variables or on immune function. The lack of effect of mixing may not reflect an...
