  1. The interplay between exposure and preference for unpalatable foods by lambs

    Contributor(s):: Villalba, Juan, Spackman, Casey, Lobón, Sandra

    Herbivores satiate on single foods ingested too frequently or in excess. We hypothesized that exposure to the same unpalatable food too frequently or in excess causes satiety, which in turn would reduce subsequent use and preference for this food when alternatives become available. In each of...

  2. Sexual behaviour in sheep is driven by body condition and the related nutritional and metabolic status

    Contributor(s):: Alhamada, Moutaz, Debus, Nathalie, González-García, Eliel, Bocquier, François

    To evaluate the effects of nutrition on the sexual behaviour of ewes, forty-eight mature (7.6±1.9years old) Merino d’Arles ewes with an average initial body condition score (BCS=2.26±0.23) and similar body weight (BW=46.6±3.8kg) were fed three contrasting diets for three months. The diets...

  3. Effects of simulated sea motion on stepping behaviour in sheep

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

    Animals respond to a moving floor during transport by stepping in different directions to maintain their balance, but little is known about the importance of different types of movement. Four sheep were restrained in a crate on a platform that could be programmed to provide the various movements...

  4. Self-administration by consumption of flunixin in feed alleviates the pain and inflammation associated with castration and tail docking of lambs

    Contributor(s):: Marini, Danila, Colditz, Ian G., Hinch, Geoff, Petherick, J. Carol, Lee, Caroline

    It can be impractical for farmers to provide pain relief to livestock following husbandry procedures such as castration and tail-docking, particularly in pasture-based systems because animals need to be repeatedly gathered to handling facilities and restrained. We investigated whether voluntary...

  5. Assessing feeding motivation in sheep using different behavioural demand models and measures

    Contributor(s):: Doughty, Amanda K., Ferguson, Drewe, Matthews, Lindsay R., Hinch, Geoff N.

    Motivation tests have been used to assess the strength of an animals drive to obtain specific resources and, indirectly to gain insight into the animal’s welfare state as it is likely that chronic high motivation for unobtainable resources leads to diminished welfare. A variety of measures have...

  6. The sucking behaviour and milk intake of one- to three-week-old triplet lambs during natural and competitive suckling situations

    Contributor(s):: Van Welie, L. A., Clews, S. A., Beausoleil, N. J., Hickson, R., Kongara, K., Kenyon, P. R., Morris, S. T.

    Within triplet litters, light-born lambs are at greater risk of dying than heavier lambs in the first week of life. However, the implications of within-litter differences in sucking behaviour for milk intake and growth beyond the first week are unclear. We hypothesized that within litter,...

  7. Do antiemetics attenuate the behavioural responses of sheep to simulated ship motion?

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

    During actual and simulated ship transport, vessel roll (sideways) and heave (vertical) movements produce behavioural responses in sheep, typically positional and feeding changes. Antiemetics may moderate these responses, hence sheep were exposed to these two movements of similar amplitude and...

  8. Behavioural assessment of sheep is sensitive to level of gastrointestinal parasite infection

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

    Qualitative behavioural assessment (QBA) was applied to investigate the expressive behaviour of sheep with varying intestinal parasite burdens over two experiments. The expressive behaviour of sheep naturally infected with intestinal parasites was assessed from video footage collected in the...

  9. Behaviour and physiology of sheep exposed to ammonia at a similar concentration to those experienced by sheep during export by sea

    Contributor(s):: Zhang, Yu, Guinnefollau, Lauréline, Sullivan, Megan, Phillips, Clive J. C.

    Ammonia accumulates in livestock accommodation, which inflames mucosal tissue to cause coughing, sneezing and lacrimation and adversely affects feed intake. We aimed to find out why feed intake is reduced for sheep in ammonia conditions typical of live export by measuring nutritional behaviour...

  10. Preference for the mother does not last long after weaning at 3 months of age in sheep

    Contributor(s):: Ungerfeld, Rodolfo, Freitas-de-Melo, Aline, Nowak, Raymond, Lévy, Frederic

    Ewes develop a strong selective bond with their offspring, which is set immediately after lambing and maintained until weaning, which in domestic sheep occurs when lambs are 4-5 months old. However, in productive systems lambs are weaned earlier, when they are 2-5 months old. The aim of this...

  11. 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...

  12. 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...

  13. 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...

  14. 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...

  15. 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...

  16. 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,...

  17. 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...

  18. 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...

  19. 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...

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

    Contributor(s):: Burgunder, Jade, Petrželková, 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...
