  1. Woollying the Boundaries: Perceptions of, and Interventions into, Upland Sheep Farming in Wales

    Full-text: Available

    | Contributor(s):: Ffion Jones

    This thesis uses an interdisciplinary methodological approach including art practice, ethnography and autoethnography as a way of examining the relationship between a farming family and their upland sheep farm in mid- Wales. It draws on the ethnographic methods of ‘participant...

  2. 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,...

  3. 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...

  4. 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...

  5. The use of quantitative risk assessment to assess lifetime welfare outcomes for breech strike and mulesing management options in Merino sheep

    | Contributor(s):: Fisher, A. D., Giraudo, A., Martin, P. A. J., Paton, M. W.

  6. Assessment of unconsciousness during slaughter without stunning in lambs

    | Contributor(s):: Rodriguez, P., Velarde, A., Dalmau, A., Llonch, P.

  7. Social transmission of physiological and behavioural responses to castration in suckling Merino lambs

    | Contributor(s):: Colditz, I. G., Paull, D. R., Lee, C.

  8. A note on sheltering behaviour by ewes before and after lambing

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

    The effects of lambing and lamb rearing on sheltering behaviour was investigated in multiparous Romney x Perendale crossbred ewes with either 9 (5 ewes) or 3 months (5) of wool growth during daylight hours for 6 weeks over the lambing period, in a pasture with little vegetative shelter but with a...

  9. Rat aversion to induction with inhalant anaesthetics

    | Contributor(s):: Makowska, I. J., Weary, D. M.

    The most common method of euthanasia of laboratory rodents is exposure to carbon dioxide (CO2), but recent studies have shown that rodents find this gas aversive. Inhalant anaesthetics such as halothane and isoflurane are commonly used to induce unconsciousness in small animals and may be a...

  10. Sheep exhibit a positive judgement bias and stress-induced hyperthermia following shearing

    | Contributor(s):: Sanger, M. E., Doyle, R. E., Hinch, G. N., Lee, C.

    The detection of judgement biases may improve welfare evaluations by measuring the cognitive component, particularly the valence, of affective states. Judgement biases have been successfully demonstrated in various laboratory animals but only recently in sheep. Chronic stressors have been found...

  11. The genetics of temperament in merino sheep and relationships with lamb survival

    | Contributor(s):: Plush, K. J., Hebart, M. L., Brien, F. D., Hynd, P. I.

    Investigations were made into the genetics of several temperament traits in Merino ewes, with particular emphasis on those aspects which might be associated with maternal behaviour at lambing and consequently, the postnatal survival of lambs. If a beneficial relationship between ewe temperament...

  12. Addressing pain caused by mulesing in sheep. (Special Issue: Pain in farm animals.)

    | Contributor(s):: Fisher, A. D.

    The surgical operation of mulesing cuts wool-bearing and wrinkled skin from the perineal region and adjoining hindquarters of Australian Merino sheep, and has been shown in combination with tail docking to provide significantly enhanced protection against flystrike for the remainder of the...

  13. Simply a nest? Effects of different enrichments on stereotypic and anxiety-related behaviour in mice

    | Contributor(s):: Gross, A. N. M., Engel, A. K. J., Wurbel, H.

    Improving the home cages of laboratory mice by environmental enrichment has been widely used to reduce cage stereotypies and anxiety-related behaviour in behavioural tests. However, enrichment studies differ substantially in type, complexity and variation of enrichments. Therefore, it is unclear...

  14. Effects of nutritional experience in early and adult life of the performance and dietary habits of sheep

    | Contributor(s):: Arnold, G. W., Maller, R. A.

    Diet selection, intake, liveweight changes and wool production were investigated in sheep grazing various sown or natural pastures or fed hay in pens. Differences in preference of spp. for grazing due to environment persisted for >1 yr despite attempts to remove them. Differences in food intake,...

  15. Statistical and probabilistic estimators of forage conditions from grazing behaviour of Merino sheep in a semi-arid environment

    | Contributor(s):: Dudzinski, M. L., Schuh, H. J., Wilcox, D. G., Gardiner, H. G., Morrissey, J. G.

    The flock structure of Merino ewes and rams was recorded from the air in 22 surveys over 3 yr in a large semi-arid area of W. Australia. Forage production and body wt. data were collected over the same period. A dispersion index, DI (with zero value when all the sheep were in 1 group and with...

  16. Use of shelter and selection of lambing sites by shorn and unshorn ewes in paddocks with closely or widely spaced shelters

    | Contributor(s):: Alexander, G., Lynch, J. J., Mottershead, B. E.

    In late winter sheep spent more time sheltering behind phalaris hedges set 20 m apart than behind those set 240 m apart, but spent more time behind the latter than behind plastic mesh screens set at the same distance. About half the ewes isolated themselves for lambing, which took place near...

  17. Repeated transport and isolation during pregnancy in ewes: differential effects on emotional reactivity and weight of their offspring

    | Contributor(s):: Roussel-Huchette, S., Hemsworth, P. H., Boissy, A., Duvaux-Ponter, C.

    The aim of this experiment was to study the effects of different stressors applied to pregnant ewes during the last third of pregnancy on the emotional reactivity of their lambs. Forty ewes were subjected twice a week during the last 6 weeks of gestation to 10 sessions of isolation (ISOL, n=20)...

  18. Neonatal survival: contributions from behavioural studies in sheep

    | Contributor(s):: Nowak, R.

    Newborn lambs need milk and immunological protection shortly after birth, and early interactions between the mother and the young are critical for this. Merino ewes in extensive conditions in Australia have the reputation of being a poor mothers. Attempts to improve the reproductive performance...

  19. Social cohesion in groups of sheep: effect of activity level, sex composition and group size

    | Contributor(s):: Michelena, P., Gautrais, J., Gerard, J. F., Bon, R., Deneubourg, J. L.

    We investigated the effects of activity, group size and sex composition on the cohesion of merino sheep (Ovis aries) groups. Mixed-sex (50% of each sex) and single-sex groups of 2, 4, 6 and 8 sheep were placed within 491-m2 arenas located in natural pastures and were video recorded during 6 daily...

  20. An evaluation of the contribution of isolation, up-ending and wool removal to the stress response to shearing

    | Contributor(s):: Hargreaves, A. L., Hutson, G. D.

    A 2x2x2 factorial experiment examined the effects of 3 components of shearing (isolation, up-ending and wool removal) on the development of a stress response to handling. 10 Merino wethers were allocated to each treatment. Haematocrit, plasma cortisol and plasma glucose were measured in a series...
