    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...

  7. 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...

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

    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...

  9. 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...

  10. 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...

  11. 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...

  12. 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...

  13. 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...

  14. 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....

  15. Effect of postweaning handling strategies on welfare and productive traits in lambs
