Classifying the posture and activity of ewes and lambs using accelerometers and machine learning on a commercial flock
Contributor(s):: Price, Emily, Langford, Joss, Fawcett, Tim W., Wilson, Alastair J., Croft, Darren P.
Early decision making in commercial livestock systems is key to maximising animal welfare and production. Detailed information on an animal’s phenotype is needed to facilitate this, but can be difficult to obtain in a commercial setting. Research into the use of bio-logging on sheep to...

Compared to grouped lambing, isolation favorize calmer animals and faster mother-lamb recognition but not lambs’ survival in tropical hair sheep farms
Contributor(s):: Escobedo-Canul, Juan A., González-Pech, Pedro G., Sandoval-Castro, Carlos A., Cámara-Sarmiento, Ramón, Sarmiento-Franco, Luis
The aim of this study was to compare the mother-lamb bonding and lamb mortality observed on Pelibuey ewes lambing in isolation (IL) or group (GL) under tropical farm conditions. Each treatment was conformed with 16 adults multiparous Pelibuey ewes of similar weight (39.8 ± 8.01 kg) and body...
Sheep Farmers' Perception of Welfare and Pain Associated with Routine Husbandry Practices in Chile
| 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...
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...
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...
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...
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...
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...
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...
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...
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...
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...

| 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...
