  1. Effects of exposing pigs to moving and odors in a simulated slaughter chute

    Contributor(s):: Krebs, N., McGlone, J. J.

    Pigs in the finishing stage are infrequently handled and can be difficult to handle when experiencing novel situations. This study sought to determine the effects of minimal training and a novel odor/taste reward on the ease of handling finishing pigs in a novel environment. Pigs were assigned to...

  2. Genetic analysis of reactivity to humans in Goettingen minipigs

    Contributor(s):: Kohn, F., Sharifi, A. R., Simianer, H.

    Goettingen minipigs are laboratory animals with an increasing demand over the last few years. At the moment, Goettingen minipigs are not selected for a low reactivity to humans and this trait is not included in the breeding programme. However, it is obvious that there is a need for genetically...

  3. Handling effects on body weight and behaviour of group-housed male rabbits in a laboratory setting

    Contributor(s):: Verwer, C. M., Amerongen, G. van, Bos, R. van den, Hendriksen, C. F. M.

    In the study described in this paper we focus on the behaviour of male rabbits under modified housing conditions. We investigated whether handling has an effect on the behavioural stress response and whether this response is related to the coping strategy of the rabbits. Furthermore we studied...

  4. Handling-induced tonic/clonic seizures in captive born bank voles ( Clethrionomys glareolus )

    Contributor(s):: Schonecker, B.

    Handling-induced seizures observed among 23 of 333 captive born bank voles was characterized by tonic/clonic convulsions, occasionally accompanied by an apparent loss of consciousness. Seizures were never observed among wild caught voles (N=71). Median age for first observation of seizures was...

  5. How do miniature pigs discriminate between people? The effect of exchanging cues between a non-handler and their familiar handler on discrimination

    Contributor(s):: Koba, Y., Tanida, H.

    During a 3-week handling period, six 8-week-old pigs were touched and fed raisins as a reward whenever they approached their handler, In subsequent training, the handlers and a non-handler wearing dark blue and white overalls, respectively, and wearing different eau de toilette fragrances sat at...

  6. Maternal behaviour in Mus musculus sp.: an ethological review

    Contributor(s):: Weber, E. M., Olsson, I. A. S.

    In this paper, we review the scientific literature on maternal behaviour in commensal house mice and laboratory mice. Similar to other altricial species, female mice prepare a nest before parturition. Once the pups are born, nursing is the main part of maternal behaviour, and pups are weaned...

  7. Pain and discomfort in male piglets during surgical castration with and without local anaesthesia as determined by vocalisation and defence behaviour

    Contributor(s):: Leidig, M. S., Hertrampf, B., Failing, K., Schumann, A., Reiner, G.

    Surgical castration of male piglets without anaesthesia is routine in domestic pig production causing serious distress and impairment of welfare. Thus, the EU is seeking alternatives, with local anaesthesia being one of the possible candidates. The aim of the present study was to compare surgical...

  8. Previous handling and gentle interactions affect behaviour and heart rate of dairy cows during a veterinary procedure

    Contributor(s):: Waiblinger, S., Menke, C., Korff, J., Bucher, A.

    Veterinary and management procedures often are aversive to the animals, resulting in physiological and behavioural stress reactions, which increase the risk of accidents and might lower performance. We investigated the effects of previous positive handling and of gentle interactions during the...

  9. Prior handling does not significantly reduce the stress response to pre-slaughter handling in broiler chickens

    Contributor(s):: Kannan, G., Mench, J. A.

    Two experiments were conducted to determine whether previously handled male broilers would show a decreased corticosterone (CORT) response to commercial-type handling at market age. In Experiment 1, 36 broilers were either repeatedly handled (H) or not handled (NH) from day 1 to 6 weeks of age....

  10. Quality of handling and holding yard environment, and beef cattle temperament: 1. Relationships with flight speed and fear of humans

    Contributor(s):: Petherick, J. C., Doogan, V. J., Holroyd, R. G., Olsson, P., Venus, B. K.

    Numerous tests have been used to measure beef cattle temperament, but limited research has addressed the relationship between such tests and whether temperament can be modified. One-hundred-and-forty-four steers were given one of three human handling and yarding experiences on six occasions...

  11. Quality of handling and holding yard environment, and beef cattle temperament: 2. Consequences for stress and productivity

    Contributor(s):: Petherick, J. C., Doogan, V. J., Venus, B. K., Holroyd, R. G., Olsson, P.

    This experiment assessed the effects of different quality and quantity of handling and quality of the holding yard environment on the productivity and physiological parameters indicative of stress in beef cattle. One-hundred-and-forty-four steers were given one of three human handling and yarding...

  12. Quantitative and qualitative assessment of the response of foals to the presence of an unfamiliar human

    Contributor(s):: Minero, M., Tosi, M. V., Canali, E., Wemelsfelder, F.

    This work aimed to apply a combined qualitative and quantitative approach to the interpretation of an on-farm behaviour test for horses, and to examine whether 1 month of handling would affect the response of yearlings to an unfamiliar stationary human in their home environment. Throughout a...

  13. Sow behaviour towards humans during standard management procedures and their relationship to piglet survival

    Contributor(s):: Lensink, B. J., Leruste, H., Bretagne, T. de, Bizeray-Filoche, D.

    Piglet crushing remains a major problem in pig production and is partly related to sow behavioural traits. The sows' responses to the presence of humans around farrowing could partly contribute to piglet crushing through increased reactivity and getting up and lying down behaviour. The aim of the...

  14. The aversiveness of carbon dioxide stunning in pigs and a comparison of the CO<sub>2</sub> stunner crate vs. the V-restrainer

    Contributor(s):: Jongman, E. C., Barnett, J. L., Hemsworth, P. H.

    Using aversion learning techniques, the relative aversiveness of CO2 to pigs in comparison to a shock with an electric prodder, and the aversiveness of a CO2-stunner crate in comparison to the aversiveness of a V-belt restrainer used for electric stunning were examined. A total of 88 boars were...

  15. The effects of early training sessions on the reactions of foals at 1, 2, and 3 months of age

    Contributor(s):: Williams, J. L., Friend, T. H., Toscano, M. J., Collins, M. N., Sisto-Burt, A., Nevill, C. H.

    An early training procedure commonly termed "foal imprint training" is widely promoted in the horse industry. However, there have been no published scientific investigations of its efficacy. This study determined the effects of a training procedure on foals and their reaction to stimuli used in...

  16. The influence of adverse or gentle handling procedures on sexual behaviour in fearful and confident sows

    Contributor(s):: Pedersen, L. J., Damm, B. I., Kongsted, A. G.

    In the present study, the influence of handling during lactation on fear of humans and on sexual behaviour in the presence and absence of a human was investigated. Prior to handling, the sows were selected as being either fearful (n=24) or confident (n=24) towards humans based on their reactions...

  17. The presence of the dam during handling prevents the socialization of young calves to humans

    Contributor(s):: Krohn, C. C., Boivin, X., Jago, J. G.

    The effect of handling and hand-feeding of calves with or without their dams present on the calves' subsequent response to humans was investigated using 5 groups of 10 Danish Friesian calves, each of which received a different treatment. The treatments were: calf separated from its dam...

  18. The relationships between temperament during routine handling tasks, weight gain and facial hair whorl position in frequently handled beef cattle

    Contributor(s):: Olmos, G., Turner, S. P.

    A relationship has been described between facial hair whorl position and temperament in infrequently handled beef cattle when both traits were measured on categorical scales. Hair whorl position has also been found to relate to daily weight gain in dairy heifers. Using both a categorical scale...
