  1. Farmer and public attitudes toward lamb finishing systems

    Contributor(s):: Coleman, G., Jongman, E., Greenfield, L., Hemsworth, P.

    To develop research and policy on the welfare of lambs in intensive finishing systems, it is important to understand public and sheep farmers' attitudes. The aim of this research was to identify and compare farmer and community attitudes relevant to the intensification of lamb finishing. The...

  2. Assessment of aversion and unconsciousness during exposure to carbon dioxide at high concentration in lambs

    Contributor(s):: Rodriguez, P., Dalmau, A., Manteca, X., Litvan, H., Jensen, E. W., Velarde, A.

    The most widely used stunning method in sheep is electrical. However, in lambs, this method leads to rupture of the blood vessels, provoking ecchymoses. In pigs ( Sus scrofa), the use of CO 2-stunning systems has increased in popularity due to positive effects on meat quality and animal welfare...

  3. Behavioural reactivity of ewes and lambs during partial and total social isolation

    Contributor(s):: Barnard, S., Matthews, L. R., Messori, S., Vulpiani, M. P., Ferri, N.

    This work investigated the differences in the reactivity of Sarda (primiparous n=18, multiparous n=17) and Dorset (multiparous n=8) breeds of sheep and their singleton lambs to two challenging test situations involving a mother-lamb partial separation test and an isolation test. Non-parametric...

  4. Filial attachment in sheep: similarities and differences between ewe-lamb and human-lamb relationships

    Contributor(s):: Nowak, R., Boivin, X.

    Animals develop relationships with intra- and interspecific partners, including humans. In some cases this can lead to strong emotional bonds indicating the existence of attachment. The sheep is well known to develop various forms of social attachment (mothers towards young, lambs towards...

  5. Space allowance during gestation and early maternal separation: effects on the fear response and social motivation of lambs

    Contributor(s):: Averos, X., Marchewka, J., Beltran de Heredia, I., Zanella, A. J., Ruiz, R., Estevez, I.

    A common prenatal stressor in lambs is early maternal separation, which may be aggravated by spatial restriction of ewes during pregnancy. They may influence lambs' development and coping abilities. The aim of this study was to determine how space allowance provided to ewes during pregnancy and...

  6. Do rubber rings coated with lignocaine reduce the pain associated with ring castration of lambs?

    Contributor(s):: Stewart, M., Beausoleil, N. J., Johnson, C. B., Webster, J. R., Schutz, K. E., Cox, N., Stafford, K. J.

    To facilitate the wider use of pain relief on-farm, practical 'farmer friendly' methods for administering pain relief are necessary. This proof of concept study evaluated the efficacy of rubber rings coated with local anaesthetic (LA, lignocaine) for providing pain relief in lambs castrated 4...

  7. Investigating the motivation to play in lambs

    Contributor(s):: Chapagain, D., Uvnas-Moberg, K., Lidfors, L. M.

    The aim of this study was to identify behaviours and ear postures linked to the appetitive, consummatory and post-consummatory motivational phases of play in male lambs, and to evaluate how cortisol was affected by play. Ten pairs of male lambs, Ovis aries were observed in a play arena three...

  8. Behavior of lambs in rest pens during long-distance transport

    Contributor(s):: Krawczel, P. D., Friend, T. H., Archer, G. S.

    The aim of this study was to determine how one group of lambs utilized 2 consecutive rest periods in novel environments with access to food and water that occurred during 22 hr of motor transport. The 18.5+or-0.6 kg lambs (n=15) were transported for 8 hr and then unloaded for a 6-hr rest period....

  9. A comparison of handling methods relevant to the religious slaughter of sheep

    Contributor(s):: Bates, L. S. W., Ford, E. A., Brown, S. N., Richards, G. J., Hadley, P. J., Wotton, S. B., Knowles, T. G.

    Legislation governing non-stun slaughter of sheep in England requires that they are individually and mechanically restrained for slaughter and not moved for at least 20 s post neck cut, until unconsciousness or insensibility occurs. Complying with the need for individual handling, in what is a...

  10. Repeated exposure to positive events induces optimistic-like judgment and enhances fearfulness in chronically stressed sheep

    Contributor(s):: Destrez, A., Deiss, V., Leterrier, C., Calandreau, L., Boissy, A.

    Chronic stress in farm animals can induce detrimental effects in emotional sensitivity and cognitive function, for example, by altering fearfulness and eliciting pessimistic-like judgment. Based on a few experiments carried out on laboratory animals, we suggest that exposing chronically stressed...

  11. Social context and other factors influence the behavioural expression of pain by lambs

    Contributor(s):: Guesgen, M. J., Beausoleil, N. J., Minot, E. O., Stewart, M., Stafford, K. J.

    There is evidence that the presence of a conspecific can alter the experience of pain in humans and other animals. This 'social buffering' may be mediated by factors such as relatedness and familiarity. This study investigates whether and how the social context affects the behavioural response of...

  12. Mobile abattoir versus conventional slaughterhouse - impact on stress parameters and meat quality characteristics in Norwegian lambs

    Contributor(s):: Eriksen, M. S., Rodbotten, R., Grondahl, A. M., Friestad, M., Andersen, I. L., Mejdell, C. M.

    The aim of the present study was to investigate possible differences in certain stress parameters and meat quality characteristics between Norwegian lambs slaughtered at a mobile abattoir (at two different localities) versus lambs slaughtered at a conventional, stationary slaughterhouse. Lambs...

  13. Performance of sheep in a spatial maze is impeded by negative stimuli

    Contributor(s):: Doyle, R. E., Freire, R., Cowling, A., Knott, S. A., Lee, C.

    Exposure to negative stimuli or stress can manifest in general changes in cognitive processing. This study aimed to investigate if a spatial maze task could be used to identify stress-induced differences in the cognitive performance of sheep. Two negative stimuli were used to test the hypothesis....

  14. Chronic stress induces pessimistic-like judgment and learning deficits in sheep

    Contributor(s):: Destrez, A., Deiss, V., Levy, F., Calandreau, L., Lee, C., Chaillou-Sagon, E., Boissy, A.
