  1. Inducing positive emotions: Behavioural and cardiac responses to human and brushing in ewes selected for high vs low social reactivity

    Contributor(s):: Tamioso, Priscilla Regina, Maiolino Molento, Carla Forte, Boivin, Xavier, Chandèze, Hervé, Andanson, Stéphane, Delval, Éric, Hazard, Dominique, da Silva, Guilherme Parreira, Taconeli, Cesar Augusto, Boissy, Alain

    Welfare concerns not only the absence of negative emotional experiences but also the presence of positive experiences. However, scientific investigation on positive emotions in farm animals has been long neglected. This study aimed to investigate the perception of sheep to positive stimuli and...

  2. Assessment of circadian rhythm of activity combined with random regression model as a novel approach to monitoring sheep in an extensive system

    Contributor(s):: Nunes Marsiglio Sarout, Bruna, Waterhouse, Anthony, Duthie, Carol-Anne, Candal Poli, Cesar Henrique Espirito, Haskell, Marie J., Berger, Anne, Umstatter, Christina

    Sensor-based technologies are becoming increasingly available and can be used to automatically gather long-term data about animal behaviour. With this information, it is possible to assess the circadian rhythm of activity and monitor its response to internal and external factors. Identifying...

  3. The effects of regularity of simulated ship motions on the behaviour and physiology of sheep

    Contributor(s):: Santurtun, Eduardo, Phillips, Clive J. C.

    Floor movement influences sheep responses to transport, but the importance of movement regularity and interactions between sheep are unknown. To test this, sheep were restrained in pairs in a crate mounted on a moveable, programmable platform for 60 min periods, changing treatments over 12...

  4. Effects of space allowance and simulated sea transport motion on behavioural and physiological responses of sheep

    Contributor(s):: Navarro, Grisel, Col, Ramazan, Phillips, Clive J. C.

    Transporting sheep by sea exposes them to some prolonged floor motions, and their responses may depend on their space allowance. We simulated sea motion in a crate with a moveable and programmable floor, to measure behaviour and physiological responses. Nine sheep were exposed in groups of 3 for...

  5. Visual attention and cognitive performance in sheep

    Contributor(s):: McBride, Sebastian D., Morton, A. Jennifer

    Cognitive probes are increasingly being used as an inferred measure of the emotional (and thus welfare) status of the animal. This reflects the bidirectional and interactive nature of emotional and cognitive systems. To date, cognitive paradigms have focused on how the emotional system biases...

  6. What can the quantitative and qualitative behavioural assessment of videos of sheep moving through an autonomous data capture system tell us about welfare?

    Contributor(s):: Grant, Emily P., Brown, Amy, Wickham, Sarah L., Anderson, Fiona, Barnes, Anne L., Fleming, Patricia A., Miller, David W.

    Sheep can be exposed to a variety of challenges and failure to adapt to these challenges can compromise their health and wellbeing. Regular monitoring of stock on large-scale or extensive systems may not always be possible, although recent technological advancements in automated data capture,...

  7. Influence of low pasture allowance during pregnancy on the attachment between ewes and their lambs at birth and during lactation

    Contributor(s):: Freitas-de-Melo, Aline, Terrazas, Angélica, Ungerfeld, Rodolfo, Hötzel, Maria José, Orihuela, Agustín, Pérez-Clariget, Raquel

    Nutrient restriction during pregnancy may negatively affect ewe-lamb attachment at birth. We hypothesised that the difference in the attachment at birth could persist during lactation and, consequently, the emotional response of lambs to a short-term maternal separation test during late...

  8. Growing without a mother during rearing affects the response to stressors in rams

    Contributor(s):: Damián, Juan Pablo, Hötzel, Maria José, Banchero, Georgget, Ungerfeld, Rodolfo

    Early maternal care contributes to the normal development of the physiological, social and emotional functions of the offspring. As sheep are a strongly gregarious species, separation and isolation of an individual from the flock provokes fear and, consequently a stress response. The first aim of...

  9. Increased intake and preference for tannin-rich sainfoin (Onobrychis viciifolia) pellets by both parasitized and non-parasitized lambs after a period of conditioning

    Contributor(s):: Costes-Thiré, Morgane, Villalba, Juan J., Hoste, Hervé, Ginane, Cécile

    Ruminants select nutritious feeds and avoid deleterious ones by relying on a learning process. We tested the hypothesis that they may similarly be able to select feeds for their medicinal properties, Le. to self-medicate. Our experimental model was lambs infected with gastrointestinal nematodes...

  10. Fractal measures in activity patterns: Do gastrointestinal parasites affect the complexity of sheep behaviour?

    Contributor(s):: Burgunder, Jade, Petr┼żelková, Klára J., Modrý, David, Kato, Akiko, MacIntosh, Andrew J. J.

    Gastrointestinal nematodes are known to be one of the most economically important parasites in livestock production. In order to test whether fractal analysis of behaviour can be used as a diagnostic tool for detection of infected animals, we investigated fractal patterns in the behavioural...

  11. Livestock guarding behaviour of Kangal dogs in their native habitat

    Contributor(s):: Akyazi, Ibrahim, Ograk, Yusuf Ziya, Eraslan, Evren, Arslan, Murat, Matur, Erdal

    Kangal Shepherd Dog is one of the endemic large dog breeds in Anatolia, Turkey. It is bred in different regions of Turkey as well as in different countries as a livestock guarding dog (LGD). Being one of the most popular and common LGD breeds, basic behavioural traits and the effectiveness of...

  12. Tempo and Mode of Domestication During the Neolithic Revolution: Evidence from Dental Mesowear and Microwear of Sheep

    Full-text: Available

    | Contributor(s):: Melissa Zolnierz

    The Neolithic Revolution marked a dramatic change in human subsistence practices. In order to explain this change, we must understand the motive forces behind it. Researchers have proposed many different stimuli, with most theories invoking environmental dynamics, human population density...

  13. Identification of QTLs for behavioral reactivity to social separation and humans in sheep using the OvineSNP50 BeadChip

    Full-text: Available

    | Contributor(s):: Dominique Hazard, Carole Moreno, Didier Foulquié, Eric Delval, Dominique François, Jacques Bouix, Guillaume Sallé, Alain Boissy

    Background Current trends in sheep farming practices rely on animals with a greater level of behavioral autonomy than before, a phenotype that actively contributes to the sustainability of animal production. Social reactivity and reactivity to humans are relevant behavioral traits in sheep,...

  14. Perception of animal sentience by Brazilian and French citizens: The case of sheep welfare and sentience

    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...

  16. Relationships between handling, behaviour and stress in lambs at abattoirs

    | Contributor(s):: Hemsworth, P. H., Rice, M., Borg, S., Edwards, L. E., Ponnampalam, E. N., Coleman, G. J.

  17. Addressing the Challenges of Conducting Observational Studies in Sheep Abattoirs

    | Contributor(s):: Elyssa Payne, Melissa Starling, Paul McGreevy

    The competing needs of maintaining productivity within abattoirs, and maintaining high standards of animal welfare, provide fertile grounds for applied research in animal behavior. However, there are challenges involved in capturing useful behavioral data from the supply chain (from paddock to...

  18. Pregnant Sheep in a Farm Environment Did Not Develop Anaemia

    | Contributor(s):: Gabrielle C. Musk, Amanda James, Matthew W. Kemp, Sara Ritchie, Andrew Ritchie, Michael Laurence

    The aim of this study was to document the haematological profile of pregnant ewes throughout gestation. Sheep were divided into three groups (n = 8 per group): non-pregnant, singleton, or twin pregnancy. Blood samples were collected every 14 days from day 55 of gestation for haemoglobin...

  19. Understanding Life Skills Gained from and Reasons for Youth Participation in the Tennessee 4-H Sheep Skillathon

    | Contributor(s):: Terra Kimes Davis, Christopher T. Stripling, Carrie A. Stephens, H. Dwight Loveday

    The high number of U.S. youth exhibiting at-risk behavior points to a lack of life skills development. We determined the effects of participating in one state's 4-H sheep skillathon on youths' life skills development and the youths' reasons for participating. The target population was...

  20. Revealing the History of Sheep Domestication Using Retrovirus Integrations

    | Contributor(s):: Bernardo Chessa, Filipe Pereira, Frederick Arnaud, Antonio Amorim, Felix Goyache, Ingrid Mainland

    The domestication of livestock represented a crucial step in human history. By using endogenous retroviruses as genetic markers, we found that sheep differentiated on the basis of their "retrotype" and morphological traits dispersed across Eurasia and Africa via separate migratory...
