    Contributor(s):: Palmer, Clare

  2. Feeding behavior and the effect of photoperiod on the performance and hematological parameters of the pacama catfish ( Lophiosilurus alexandri)

    Contributor(s):: Kitagawa, A. T., Costa, L. S., Paulino, R. R., Luz, R. K., Rosa, P. V., Guerra-Santos, B., Fortes-Silva, R.

    The aim of this study was to evaluate the rhythms of feeding and locomotor activity, the ability to synchronize to a fixed feeding time, and the influence of photoperiod on the growth parameters, feed intake and hematological parameters of a recently introduced fish in freshwater Brazilian...

  3. Understanding feeding patterns in growing pigs by modelling growth and motivation

    Contributor(s):: Boumans, I. J. M. M., Bokkers, E. A. M., Hofstede, G. J., Boer, I. J. M. de

    Feeding is an essential behaviour for body maintenance in pigs and closely related to their growth and productivity performance. Mechanisms underlying feeding behaviour in pigs are still unclear. Understanding these mechanisms can provide valuable insights into the complex interactions among...

  4. Condensed tannins reduce browsing and increase grazing time of free-ranging goats in semi-arid savannas

    Contributor(s):: Mkhize, N. R., Heitkonig, I. M. A., Scogings, P. F., Dziba, L. E., Prins, H. H. T., Boer, W. F. de

    Tannin concentrations fluctuate spatially and temporally within and among plant species, with consequences for forage quality of herbivores. The extent to which these fluctuations influence foraging activities of goats is not fully understood. While accounting for the effects of the time of the...

  5. The effect of four different feeding regimes on rabbit behaviour

    Contributor(s):: Prebble, J. L., Langford, F. M., Shaw, D. J., Meredith, A. L.

    Dietary composition and presentation impacts on the behaviour of animals, and failure to provide a suitable diet can lead to reduced welfare through the development of poor health, the inability to express normal behaviours and the development of abnormal behaviours. This study assessed the...

  6. Social behavior of domestic cats in the human home

    Contributor(s):: Bernstein, P. L., Friedmann, Erika, Turner, D. C., Bateson, P.

  7. Dogs steal in the dark

    Contributor(s):: Kaminski, J., Pitsch, A., Tomasello, M.

  8. Predicting time spent on different behavioural activities from physicochemical properties of fibrous diets in finishing pigs

    Contributor(s):: Bakare, A. G., Ndou, S. P., Madzimure, J., Chimonyo, M.

    The objective of the present study was to predict time spent on different behavioural activities by finishing pigs, using physicochemical measurements of fibrous feed. Eighty four Large White * Landrace barrows with 80.54.7 kg body weight (BW) at the beginning of the experiment were used. Feed...

  9. 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...

  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. Pet feeding practices of dog and cat owners in the United States and Australia

    Contributor(s):: Laflamme, D. P., Abood, S. K., Fascetti, A. J., Fleeman, L. M., Freeman, L. M., Michel, K. E., Bauer, C., Kemp, B. L., Doren, J. R., Willoughby, K. N.

  12. Behavior as a tool for welfare improvement and conservation management in the endangered lizard ( Gallotia bravoana )

    Contributor(s):: Mesa-Avila, G., Molina-Borja, M.

    The study assessed the behavior of Gallotia bravoana (La Gomera, Canary Islands, one of the world's most threatened reptiles) to facilitate management decisions and improve welfare during initial stages of a species' recovery plan. The study analyzed - and remote-controlled video cameras filmed -...

  13. Cage use and feeding height preferences of captive common marmosets ( Callithrix j. jacchus ) in two-tier cages

    Contributor(s):: Buchanan-Smith, H. M., Shand, C., Morris, K.

    Determining appropriate feeding regimes has important welfare implications for captive primates. This study examined the preference of food bowl heights in 6 pairs of common marmosets (Callithrix jacchus) housed in a 2-tier cage system. Given that marmosets are arboreal and spend most of their...

  14. 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)...

  15. Do domestic pigs in controlled environments contrafreeload?

    Contributor(s):: Young, R. J., Lawrence, A. B.

    Many experiments report that animals will work (lever press) for food in the presence of freely available identical food. This phenomenon has attracted the attention of applied ethologists because it seems to prove that animals have a need to express appetitive behaviour. If this is the case,...

  16. Effect of diet change on the behavior of chicks of an egg-laying strain

    Contributor(s):: Dixon, G., Green, L. E., Nicol, C. J.

    Injurious pecking has serious welfare consequences in flocks of hens kept for egg laying, especially when loose-housed. Frequent diet change is a significant risk for injurious pecking; how the mechanics of diet change influence pecking behavior is unknown. This study investigated the effect of...

  17. 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...

  18. 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...

  19. 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...

  20. 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...
