    Full-text: Available

    | Contributor(s):: Cristian Larrondo, Hedie Bustamante, Carmen Gallo

    Considering the public concern about the welfare of farm animals during routine husbandry practices, this study aimed to determine how husbandry practices are carried out in Chilean farms, sheep farmers’ perceptions of animal welfare and pain, and factors that affect them, as well as the...

  4. Mid- and late-pregnancy ewe shearing affects lamb neonatal reactivity and vigour

    | Contributor(s):: Labeur, Léa, Small, Alison H., Hinch, Geoff N., McFarlane, James R., Schmoelzl, Sabine

    Poor lamb survival is an important production and welfare issue, and the lamb must express complex behaviours to successfully transition to life ex-utero. Even under best management practices, sheep husbandry events, such as shearing, yarding and transport can be stressful for animals, and when...

  5. Validation of accelerometers to automatically record postures and number of steps in growing lambs

    | Contributor(s):: Högberg, Niclas, Höglund, Johan, Carlsson, Annelie, Saint-Jeveint, Marie, Lidfors, Lena

    We validated the accuracy of two commercially available activity loggers for cattle in determining lying and standing durations, number of lying bouts and number of steps in growing lambs. Ten growing lambs divided into two weight classes were fitted with an IceTag on the right hind leg and an...

  6. Farmer and Public Attitudes Toward Lamb Finishing Systems

    | Contributor(s):: Coleman, Grahame, Jongman, Ellen, Greenfield, L., Hemsworth, Paul

    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...

  7. 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...

  8. Mobile abattoir versus conventional slaughterhouse—Impact on stress parameters and meat quality characteristics in Norwegian lambs

    | Contributor(s):: Eriksen, Marit Skog, Rødbotten, Rune, Grøndahl, Ann Margaret, Friestad, Mari, Andersen, Inger Lise, Mejdell, Cecilie 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...

  9. Investigating the motivation to play in lambs

    | Contributor(s):: Chapagain, Durga, Uvnäs-Moberg, Kerstin, Lidfors, Lena 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...

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

    | Contributor(s):: Stewart, Mairi, Beausoleil, Ngaio J., Johnson, Craig B., Webster, James R., Schütz, Karin E., Cox, Neil, Stafford, Kevin 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...

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

    | Contributor(s):: Plush, Kate J., Hebart, Michelle L., Brien, Forbes D., Hynd, Philip 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. Ewes are more attentive to their offspring experiencing pain but not stress

    | Contributor(s):: Hild, Sophie, Clark, Corinna C. A., Dwyer, Catherine M., Murrell, Joanna C., Mendl, Mike, Zanella, Adroaldo J.

    The goal of this experiment was to detect if maternal care by ewes could be effective in mitigating psychological or physiological stress or pain in their offspring. We hypothesised that ewes are able to recognise when their offspring undergo an adverse experience and will adapt their maternal...

  13. The effects of journey duration and space allowance on the behavioural and biochemical measurements of stress responses in suckling lambs during transport to an abattoir

    | Contributor(s):: de la Fuente, Jesús, de Chávarri, Elisabeth González, Sánchez, Mónica, Vieira, Ceferina, Lauzurica, Sara, Díaz, Maria Teresa, Pérez, Concepción

    To evaluate the effect of journey duration and space allowance on behavioural and physiological responses, 72 male suckling lambs were transported by road to the slaughterhouse using two transport times – short (around 40min) or long (around 4.75h) – and three different space allowances: 0.12...

  14. The effects of age and sex on pain sensitivity in young lambs

    | Contributor(s):: Guesgen, Mirjam J., Beausoleil, Ngaio J., Minot, Edward O., Stewart, Mairi, Jones, Geoff, Stafford, Kevin J.

    Lambs routinely undergo painful husbandry procedures including ear tagging, tail docking and castration. Pain early in life is important because it can compromise lamb welfare. Studies of altricial species, such as rodents and humans, suggest that baseline pain sensitivity varies with age and...

  15. Effect of pre-weaning temporary isolation within different age periods on the early post-weaning behaviour of juvenile lambs

    | Contributor(s):: Simitzis, Panagiotis, Petrou, Miria, Demiris, Nikos, Deligeorgis, Stelios

    Temporary maternal separation is a stressful situation typical under modern husbandry practices and may have an undesirable impact on lamb welfare. However, at present there is insufficient evidence on temporary maternal separation effects on the behaviour of juvenile lambs. The aim of the...

  16. Effect of a short-term training on intake of Halocnemum strobilaceum forage by sheep

    | Contributor(s):: Sadeghi, Mohammad-Hadi, Sari, Mohsen, abadi, Tahereh Mohammad, Rezai, Morteza

    Halocnemum strobilaceum (Chenopodiaceae) is a halophyte plant that can produce relatively high consumable biomass during drought and it is important for sustaining grazing animals when other plants are rare. Previous studies indicate that sheep may avoid the plant due to its novelty or neophobia....

  17. The effect of social dynamics and environment at time of early weaning on short- and long-term lamb behavior in a pasture and feedlot setting

    | Contributor(s):: Pullin, Allison N., Pairis-Garcia, Monique D., Campbell, Braden J., Campler, Magnus R., Proudfoot, Kathryn L., Fluharty, Francis L.

    Lambs are commonly weaned around 60 d of age in the Eastern United States, but this age is also a time for lambs to apply long-term feeding strategies learned from adult animals. There is minimal evidence on how weaning strategies may affect long-term adaptation of feeding behavior. The objective...

  18. Positive perception of human stroking by lambs: Qualitative behaviour assessment confirms previous interpretation of quantitative data

    | Contributor(s):: Serrapica, Maria, Boivin, Xavier, Coulon, Marjorie, Braghieri, Ada, Napolitano, Fabio

    Qualitative behaviour assessment (QBA) was used to validate previous published interpretation whether human stroking has beneficial effects on lambs prematurely separated from their mothers. For a period of 8 weeks a familiar human (FH) subjected 22 Romane lambs to a gentling treatment based on...

  19. The effect of trough space and floor space on feeding and welfare of lambs in an intensive finishing system

    | Contributor(s):: Jongman, Ellen C., Rice, Maxine, Campbell, Angus J. D., Butler, Kym L., Hemsworth, Paul H.

    This study examined the effects of floor space and feeder space on the feeding behaviour, growth and stress physiology of lambs, at different times, over a 6-week period in a finishing feedlot. A total of 640 lambs in four time replicates (160 lambs per replicate) were studied in four 40-lamb...

  20. Relationships between temperament, feeding behaviour, social interactions, and stress in lambs adapting to a feedlot environment

    | Contributor(s):: Rice, Maxine, Jongman, Ellen Caroline, Butler, Kym Lloyd, Hemsworth, Paul Hamilton

    The production of lamb meat is a large and important industry in Australia. Variability and seasonality of the climate and the demand for a consistent product (in terms of weight and age) have led to an increase in the use of feedlot systems for finishing lambs. While most lambs acclimatise to...
