  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. 'subordination style' in pigs? The response of pregnant sows to mixing stress affects their offspring's behaviour and stress reactivity

    Contributor(s):: Ison, S. H., D'Eath, R. B., Robson, S. K., Baxter, E. M., Ormandy, E., Douglas, A. J., Russell, J. A., Lawrence, A. B., Jarvis, S.

    In various mammals stress during gestation can result in long term effects on the behaviour and physiology of the offspring. The aims of this study were (i) to characterise individual variation among primiparous sows (gilts) in their behavioural and physiological response to a commercially...

  3. A behavioural study of scrapie-affected sheep

    Contributor(s):: Healy, A. M., Hanlon, A. J., Weavers, E., Collins, J. D., Doherty, M. L.

    The behaviour of 12 sheep, suspected of having scrapie, and 12 clinically normal animals from the Irish Republic was observed over a 6-day period [date not given]. Confirmation of the true disease status of the animals was made at postmortem using both histopathological and immunocytochemical...

  4. A brief note on the relationship between residual feed intake and aggression behaviour in juveniles of African catfish Clarias gariepinus

    | Contributor(s):: Martins, C. I. M., Hillen, B., Schrama, J. W., Verreth, J. A. J.

    Individual differences in maintenance levels have been related with energetically expensive processes such as aggression. This relationship is not fully understood as on one hand individuals with higher maintenance requirements seem to be more aggressive but on the other hand have smaller...

  5. A case control study of on-farm risk factors for tail biting in pigs

    | Contributor(s):: Moinard, C., Mendl, M., Nicol, C. J., Green, L. E.

  6. A cautionary note regarding the use of nutritional L-tryptophan to alter aversion-related behaviour in mice

    | Contributor(s):: Janczak, A. M., Bakken, M., Braastad, B. O.

    Nutritional L-tryptophan is reported to have positive effects on the behaviour of several farm animals. The present experiment describes some effects of nutritional L-tryptophan on the aversion-related behaviour of male mice selected for high litter size. The behavioural effects of L-tryptophan...

  7. A colostrum feeder for newborn lambs

    | Contributor(s):: Fraser, D., Rushen, J.

    Newborn lambs were studied in 6 experiments to identify simple cues that elicit teat-seeking behaviour, and to incorporate these cues into a device that would guide lambs to find and suck from a colostrum bottle. Lambs were removed from the ewe before sucking and were observed for 10 min in a...

  8. 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...

  9. A comparison of food selection and foraging behavior in juvenile and adult goats

    | Contributor(s):: Provenza, F. D., Malechek, J. C.

    Young animals on rangelands are at an inherent disadvantage to older animals because they have higher nutritional requirements and they lack foraging experience. Comparisons were made in diet selection, foraging time and weight changes for adult (does) and juvenile (kids) goats foraging at two...

  10. A comparison of operant responding by farrowing sows for food and nest-building materials

    | Contributor(s):: Hutson, G. D.

    In experiments on 4 days immediately before and after parturition with 16 sows trained to lift a lever to gain access to either a box containing straw, a box containing sticks, an empty box, or a food drop, sows lifted more for food than for the empty box or nest-building materials. On any day...

  11. A comparison of space requirements of horned and hornless goats at the feed barrier and in the lying area

    | Contributor(s):: Loretz, C., Wechsler, B., Hauser, R., Rusch, P.

    Loose housing of horned goats is more common than loose housing of horned cattle, and recommendations concerning the design of housing systems for horned goats are needed. In this study, we compared the behaviour of horned and hornless goats kept in deep litter pens to investigate their space...

  12. A comparison of the activity budgets of wild and captive Sulawesi crested black macaques ( Macaca nigra )

    | Contributor(s):: Melfi, V. A., Feistner, A. T. C.

    One aim of environmental enrichment techniques is to replicate 'wild-like' behaviour in captivity. In this study, three captive troops of Sulawesi crested black macaques (M. nigra) in Chester, Jersey and Marwell Zoos, UK were each observed for 100 h in large naturalistic enclosures In May and...

  13. A comparison of weaning techniques in farmed wapiti ( Cervus elaphus )

    | Contributor(s):: Haigh, J. C., Stookey, J. M., Bowman, P., Waltz, C.

    A total of 21 wapiti calves, born between 24 May and 4 July were kept with their dams in a 5-ha paddock from 28 July to 28 August, after which they were moved to another field. On 5 September, they were weighed, divided into 2 groups (10 and 11 calves) and moved to a familiar paddock, adjacent to...

  14. A complex automatic feeding system for pigs aimed to induce successful behavioural coping by cognitive adaptation

    | Contributor(s):: Ernst, K., Puppe, B., Schon, P. C., Manteuffel, G.

    In modern intensive husbandry systems there is an increasing tendency for animals to interact with technical equipment. If the animal-technology interface is well-designed this may improve animal welfare by offering challenges for cognitive adaptation. Here a system and its application is...

  15. 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...

  16. 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...

  17. A method for assessing the relative sociability of individuals within groups: an example with grazing sheep

    | Contributor(s):: Sibbald, A. M., Elston, D. A., Smith, D. J. F., Erhard, H. W.

    We describe a method for quantifying relative sociability within a group of animals, which is defined as the tendency to be close to others within the group and based on the identification of nearest neighbours. The method is suitable for groups of animals in which all individuals are visible and...

  18. A method for quantification of jaw movements suitable for use on free-ranging cattle

    | Contributor(s):: Matsui, K., Okubo, T.

    A data-logging system for the simultaneous measurement of the J-J interval (the interval between two successive jaw movements), the number of jaw movements and the number of pauses between jaw movements longer than 3 s was developed and tested in free-ranging cattle. The system, which consists of...

  19. 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...

  20. 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...
