  1. Transcranial magnetic stunning of broilers: a preliminary trial to induce unconsciousness

    Contributor(s):: Lambooij, E., Anil, H., Butler, S. R., Reimert, H., Workel, L., Hindle, V.

    This study was performed to identify whether non-focal transcranial magnetic stimulation (TMS) with an adapted coil for broilers has the potential for use as a non-invasive stunning method for broilers. Application of the TMS probe resulted in dominance of theta and delta waves and appearance of...

  2. Head-only electrical stunning and bleeding of African catfish ( Clarias gariepinus ): assessment of loss of consciousness

    Contributor(s):: Lambooij, E., Kloosterboer, R. J., Gerritzen, M. A., Vis, J. W. van de

    The objective was to evaluate the welfare implications of electrical stunning prior to gill-cutting of farmed African catfish as an alternative to live chilling in combination with gutting. Electroencephalogram (EEG) and electrocardiogram (ECG) recordings, in combination with observation of...

  3. The effect of routine experimental procedures on physiological parameters in mice kept under different husbandry conditions

    Contributor(s):: Meijer, M. K., Kramer, K., Remie, R., Spruijt, B. M., Zutphen, L. F. M. van, Baumans, V.

    Laboratory animals are frequently subjected to routine procedures, such as injections or the withdrawal of blood samples. Acute stress caused by such procedures is associated with physiological changes that can have a strong impact on experimental results. This study investigated the integrated...

  4. Transport stress in roe deer ( Capreolus capreolus ): effect of a short-acting antipsychotic

    Contributor(s):: Montane, J., Marco, I., Lopez-Olvera, J., Manteca, X., Lavin, S.

    The aim of this study was to evaluate the effect of a short-acting antipsychotic (acepromazine) on the stress response to transport in roe deer (C. capreolus). 21 roe deer in France were submitted to a 9-h road journey in order to reintroduce and restock this species into Catalonia (northeastern...

  5. Heart rate and stress hormone responses of sheep to road transport following two different loading procedures

    Contributor(s):: Parrott, R. F., Hall, S. J. G., Lloyd, D. M.

    The physiological responses induced in 18 sheep by 2 different loading techniques followed by a short road journey were investigated. All animals were prepared with venous catheters, to minimize the disturbing effects of blood sampling, and 9 sheep were fitted with heart rate monitors. The...

  6. Effect of driver and driving style on the stress responses of pigs during a short journey by trailer

    Contributor(s):: Peeters, E., Deprez, K., Beckers, F., Baerdemaeker, J. D., Aubert, A. E., Geers, R.

    The aim of this study was to investigate the combined effect of driver and driving style on the behaviour, salivary cortisol concentration, and heart-rate variability of pigs during a short journey. In addition, the effect of differing accelerations (longitudinal, lateral, and vertical) of the...

  7. Effects of lighting on heart rate and positional preferences during confinement in farmed red deer

    Contributor(s):: Pollard, J. C., Littlejohn, R. P.

    In the first of 2 experiments heart rate was measured in 24 individual deer, restrained in a mechanical deer crush for 2 min, under either dark (0 lux) or light (1500 lux) conditions. A stethoscope was used to monitor heartbeat. In experiment 2, 10 groups of 3 deer were confined for 4 min in an...

  8. Infrared thermography as a non-invasive tool to study animal welfare

    Contributor(s):: Stewart, M., Webster, J. R., Schaefer, A. L., Cook, N. J., Scott, S. L.

    Growing public concern regarding animal welfare and consumer demand for humanely produced products have placed pressure on the meat, wool and dairy industries to improve and confirm the welfare status of their animals. This has increased the need for reliable methods of assessing animal welfare...

  9. Animals' emotions: studies in sheep using appraisal theories

    Contributor(s):: Veissier, I., Boissy, A., Desire, L., Greiveldinger, L.

    Animal welfare concerns stem from recognition of the fact that animals can experience emotions such as pain or joy. Nevertheless, discussion of animal emotions is often considered anthropomorphic, and there is a clear need to use explanatory frameworks to understand animals' emotions. We borrowed...

  10. The effect of transport on cortisol, glucose, heart rate, leukocytes and body weight in captive-reared guanacos ( Lama guanicoe )

    Contributor(s):: Zapata, B., Gimpel, J., Bonacic, C., Gonzalez, B. A., Riveros, J. L., Ramirez, A. M., Bas, F., Macdonald, D. W.

    Current procedures for ranching and sustainable use of guanacos necessitate their transport. Transportation is a risky process for animals, and is a particular concern for wild-caught or semi-domesticated species such as the guanaco - a wild South American camelid species increasingly being...

  11. Relation between pet ownership and heart rate variability in patients with healed myocardial infarcts

    Contributor(s):: Friedmann, E., Thomas, S. A., Stein, P. K., Kleiger, R. E.

  12. Relationship between behavioural reactions and heart rate in horses during transient social isolation

    Contributor(s):: Jezierski, T., Gorecka, A.

    Six horses were used in an experiment conducted in a tie-stable without boxes. The behaviour of each horse was videotaped and heart rate (HR) was recorded continuously for approx. 104 min during the following test situations: all horses in the stable and no person present; other horses being...

  13. The influence of the human-animal interaction in the milking parlour on the behaviour, heart-rate and milk yield of dairy cows

    Contributor(s):: Knierim, U., Waran, N. K.

    This study addressed questions regarding the quality of human-cow interactions in the modern milking parlour, and whether in this situation cows still react differently to different milkers.
