  1. "Who's been a good dog?" - Owner perceptions and motivations for treat giving

    Contributor(s):: White, G. A., Ward, L., Pink, C., Craigon, J., Millar, K. M.

    Complex relationships commonly exist between owners and their companion animals, particularly around feeding behaviour with an owner's affection or love for their animal most pronounced through the provision of food. It is notable that the pet food market is experiencing strong year-on-year...

  2. A comparative approach to the study of Keeper-Animal Relationships in the zoo. (Special Issue: Zoo animal welfare.)

    Contributor(s):: Carlstead, K.

    Research on intensively farmed animals over the past 25 years has shown that human-animal interactions, by affecting the animal's fear of humans, can markedly limit the productivity and welfare of farm animals. This article begins to explore some of the factors that need to be considered to...

  3. A comparison of the behaviour of domestic chicks reared with or without a hen in enriched pens

    Contributor(s):: Roden, C., Wechsler, B.

    The presence of a hen and the incidence of feather pecking in laying hen chicks (white 'Lohman Selected Leghorn' hybrids) was investigated. Groups of 8 chicks were reared with a hen (5 groups) or without a hen (7 groups) in enriched pens over the first 8 weeks after hatching. There was a...

  4. A comparison of the effects of simple versus complex environmental enrichment on the behaviour of group-housed, subadult rhesus macaques

    Contributor(s):: Schapiro, S. J., Bloomsmith, M. A., Suarez, S. A., Porter, L. M.

  5. A conditioned response overrides social attraction in common carp: a possibility for low stress sorting strongly schooling fish?

    Contributor(s):: Mesquita, F. O., Borcato, F. L., Huntingford, F. A.

    In this study we investigated whether a conditioned response to a light cue can override the strong schooling tendency of common carp, with a view to identifying a possible system for low stress control of movement for captive fish. Carp were trained in groups of three to approach and bite a...

  6. A flooring comparison: the impact of rubber mats on the health, behavior, and welfare of group-housed sows at breeding

    Contributor(s):: Elmore, M. R. P., Garner, J. P., Johnson, A. K., Richert, B. T., Pajor, E. A.

    Comfortable flooring may impact many aspects of an animal's welfare, including lying behavior, an animal's ability to change postures, and incidence of lameness and lesions. Therefore, we hypothesized that the addition of rubber mats to stalls of group pens would improve sow health, comfort and...

  7. A modeling approach for estimating seasonal dietary preferences of goats in a Mediterranean Quercus frainetto-Juniperus oxycedrus woodland

    Contributor(s):: Manousidis, T., Malesios, C., Kyriazopoulos, A. P., Parissi, Z. M., Abraham, E. M., Abas, Z.

    Goats are characterized as selective feeders due to their specific feeding behavior, thus the study of their seasonal preferences in a Mediterranean oak-juniper ecosystem is of great interest. The current research was conducted in an open oak forest in Megalo Dereio region, northeastern Greece...

  8. A note on alarm cues in juvenile African catfish, Clarias gariepinus Burchell: indications for opposing behavioural strategies

    Contributor(s):: Nieuwegiessen, P. G. van de, Schrama, J. W., Verreth, J. A. J.

    Following exposure of African catfish to alarm cues, a relationship (rp=0.60, N=10, P=0.07) between feed efficiency (measured as residual feed intake) and the change in percentage of time spent swimming in response to damage-released alarm cues was observed. Feed-efficient animals responded with...

  9. A note on effects of gender and time of day on the winter time-activity budget of adult ostriches ( Struthio camelus ) in a farming environment

    Contributor(s):: Deeming, D. C.

    Male and female adult ostriches, maintained in 3 pairs and 6 trios on a commercial ostrich farm in Britain, were observed for five 10-min periods in the morning and afternoon during February 1997. Weather conditions included periods of rain, high winds, overcast days and bright sunny days, and...

  10. A novel flexible method to split feeding behaviour into bouts

    Contributor(s):: Howie, J. A., Tolkamp, B. J., Avendano, S., Kyriazakis, I.

    Before meal patterns can be analysed properly, a biologically relevant meal criterion must be determined in order to group short-term feeding behaviour into meals. Existing methodologies are based on modelling of the frequency distributions of intervals between feeding events but these methods...

  11. A prospective exploration of farm, farmer, and animal characteristics in human-animal relationships: an epidemiological survey

    Contributor(s):: Roches, A. de B. des, Veissier, I., Boivin, X., Gilot-Fromont, E., Mounier, L.

    Human-animal relationships are essential for dairy farming. They affect work comfort and efficiency, as well as milk production. A poor human-animal relationship can result in stress and accidents to both animals and caretakers and needs to be improved. However, many studies have demonstrated the...

  12. A survey of abnormal repetitive behaviors in North American river otters housed in zoos

    Contributor(s):: Morabito, P., Bashaw, M. J.

    Stereotypic behaviors, indicating poor welfare and studied in a variety of species (especially carnivores), appear related to characteristics of current and past environments. Although North American river otters (Lontra canadensis) often develop abnormal, repetitive, possibly stereotypic...

  13. A survey of the attitudes of stakeholders in the zoo industry towards the husbandry requirements of captive Great Apes

    Contributor(s):: Fernie, A. C., Tribe, A., Murray, P. J., Lisle, A., Phillips, C. J. C.

  14. A test for measuring individual variation in how far grazing animals will move away from a social group to feed

    Contributor(s):: Sibbald, A. M., Erhard, H. W., Hooper, R. J., Dumont, B., Boissy, A.

    This paper describes a test for gregarious grazing animals, which measures trade-offs between feeding and social companionship. Four groups of 10 female Scottish Blackface sheep were used for the study and bowls containing food pellets were used to draw individuals away from the group. The sheep...

  15. A version of chickens to various lethal gas mixtures

    Contributor(s):: Sandilands, V., Raj, A. B. M., Baker, L., Sparks, N. H. C.

    In the event of a notifiable disease outbreak, poultry may need to be culled in situ. This should be performed swiftly and humanely to prevent further spread of the pathogen while preserving the welfare of the animals prior to death. Here, we examined the aversion of broiler chicks (Gallus...

  16. Ability of lambs to learn about novel foods while observing or participating with social models

    Contributor(s):: Thorhallsdottir, A. G., Provenza, F. D., Balph, D. F.

    The influence of different social models on the intake of novel feeds; rolled barley, the live shrub Amelanchier alnifolia and a maize grain pellet containing lithium chloride by lambs, 6 to 7 weeks old was studied. Lambs that ate novel feeds for 16 min/day for 5 days with their mothers ate about...

  17. Acute effects of cage cleaning at different frequencies on laboratory rat behaviour and welfare

    Contributor(s):: Burn, C. C., Peters, A., Mason, G. J.

  18. Aggression and social rank fluctuations in precision-fed and skip-a-day-fed broiler breeder pullets

    Contributor(s):: Girard, Teryn E., Zuidhof, Martin J., Bench, Clover J.

    In broiler breeders, conventional skip-a-day feeding leads to hunger-related aggression. As an alternative, a precision feeding system was developed to provide small meals to individual birds multiple times each day, sheltered from competition. Two objectives investigated whether: 1) aggression...

  19. Aggressive behavior in two different group-housing systems for pregnant sows

    Contributor(s):: Chapinal, N., Ruiz-de-la-Torre, J. L., Cerisuelo, A., Gasa, J., Baucells, M. D., Manteca, X.

    The study housed 120 pregnant sows from Day 29 of pregnancy to 1 week before parturition either in groups of 10 with trickle feeding (TRICKLE) or in groups of 20 with an unprotected electronic sow feeding (FITMIX). The study recorded aggressive interaction on 11 nonconsecutive days. Frequency of...

  20. Agonistic behaviour, skin lesions and activity pattern of entire male, female and castrated male finishing pigs

    Contributor(s):: Bunger, B., Schrader, L., Schrade, H., Zacharias, B.

    Fattening of intact boars is the least invasive alternative to the detrimental welfare effects of surgical castration of piglets. However, beside problems such as boar taint the divergent agonistic and sexual behaviour of boars may impair the pigs' welfare during fattening. To evaluate the effect...
