  1. On-farm qualitative behaviour assessment in sheep: repeated measurements across time, and association with physical indicators of flock health and welfare

    Contributor(s):: Phythian, C. J., Michalopoulou, E., Cripps, P. J., Duncan, J. S., Wemelsfelder, F.

    Qualitative Behavioural Assessment (QBA) is a 'whole-animal' methodology that assesses the expressive qualities of animal behaviour using terms such as 'tense', 'relaxed', 'anxious', and 'content'. The reliability and validity of QBA as an indicator for on-farm welfare assessment in pigs, cattle,...

  2. Manifestation of neuronal ceroid lipofuscinosis in Australian Merino sheep: observations on altered behaviour and growth

    Contributor(s):: Cronin, G. M., Beganovic, D. F., Sutton, A. L., Palmer, D. J., Thomson, P. C., Tammen, I.

    Neuronal ceroid lipofuscinoses (NCL) is an inherited neurodegenerative disorder in children. Presently there is no effective treatment and the disorder is lethal. NCL occur in a variety of non-human species including sheep, which are recognised as valuable large animal models for NCL. This...

  3. Mother-young behaviours at lambing in grazing ewes: effects of lamb sex and food restriction in pregnancy

    Contributor(s):: Freitas-De-Melo, A., Ungerfeld, R., Hotzel, M. J., Abud, M. J., Alvarez-Oxiley, A., Orihuela, A., Damian, J. P., Perez-Clariget, R.

    This study investigated whether the level of pasture allowance from before conception until late pregnancy affects ewe-lamb behaviours at birth, and if those behaviours differ according to the sex of the lambs. We performed two experiments, in which 96 ewes were assigned to one of two nutritional...

  4. 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...

  5. 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...

  6. 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...

  7. 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...

  8. 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...

  9. 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...

  10. 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...

  11. 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...

  12. 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....

  13. 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.

  14. The importance of diet choice on stress-related responses by lambs

    Contributor(s):: Catanese, F., Obelar, M., Villalba, J. J., Distel, R. A.

    Contributor(s):: Sumita, Sugnaseelan, Prescott, N. B., Broom, D. M., Wathes, C. M., Phillips, C. J. C.

  16. Does reduction of fearfulness tend to reduce pessimistic-like judgment in lambs?

    Contributor(s):: Destrez, A., Deiss, V., Belzung, C., Lee, C., Boissy, A.

  20. Development of affinity to the stockperson in lambs from two breeds

    Contributor(s):: Caroprese, M., Napolitano, F., Boivin, X., Albenzio, M., Annicchiarico, G., Sevi, A.

    The interactions between genetic and environmental factors on the development of lamb affinity to humans was assessed on 48 animals from two breeds (Gentile di Puglia and Comisana) and two treatments (Gentled and Not Gentled) producing 4 groups (GPg, GPng, Cg, Cng, respectively). The Gentile di...
