  1. Measurement of feeding motivation in sheep and the effects of food restriction

    Contributor(s):: Verbeek, Else, Waas, Joseph R., McLeay, Lance, Matthews, Lindsay R.

    The availability of food is a crucial factor determining the health and growth of animals. Prolonged or severe food restriction will trigger the subjective state of hunger, which could potentially reduce welfare. We refined a methodology for the measurement of feeding motivation as an indicator...

  2. The long and short of it: A review of tail docking in farm animals

    Contributor(s):: Sutherland, Mhairi A., Tucker, Cassandra B.

    Tail docking involves amputating a portion of the tail for a variety of reasons. We review the scientific evidence for the rationale for tail docking, a description of the different methods used, the pain response to the procedure and the effectiveness of pain alleviation, and, finally, the...

  3. Human–animal interactions at abattoirs: Relationships between handling and animal stress in sheep and cattle

    Contributor(s):: Hemsworth, Paul H., Rice, Maxine, Karlen, Marcus G., Calleja, Lisa, Barnett, John L., Nash, Judy, Coleman, Grahame J.

    Relationships between handling and animal stress were studied in 200 animals, of similar age from one property, at each of two sheep and two cattle abattoirs (n=800). A total of 14 and 13 stockpeople handled the study sheep and cattle, respectively. At each abattoir, 10 cohorts of 20 animals from...

  4. Does reduction of fearfulness tend to reduce pessimistic-like judgment in lambs?

    Contributor(s):: Destrez, Alexandra, Deiss, Véronique, Belzung, Catherine, Lee, Caroline, Boissy, Alain

    Recent studies emphasize the role of interactions between emotions and judgment of environment to better assess affective state in animals. Diazepam offers a way to pharmacologically manipulate the affective state. This drug is generally used to reduce negative affective states, mainly by...

  5. Castration induced pain in pigs and other livestock

    Contributor(s):: Rault, Jean-Loup, Lay, Donald C., Marchant-Forde, Jeremy N.

    Castration of male livestock being reared for meat has long been practiced, to prevent unwanted breeding, make management and handling easier, and to improve meat quality. However, castration is a painful procedure for the animal and has increasingly come under scrutiny from animal welfare...

  6. Breed differences in the expression of maternal care at parturition persist throughout the lactation period in sheep

    Contributor(s):: Pickup, Helena E., Dwyer, Cathy M.

    Maternal care plays an important role in the survival of offspring in mammals. In the ewe initial maternal care is expressed by nurturing the young and formation of an exclusive olfactory bond with the lamb. After the neonatal period, maternal care is associated with co-operation with sucking...

  7. Assessment of sociability in farm animals: The use of arena test in lambs

    Contributor(s):: Ligout, Séverine, Foulquié, Didier, Sèbe, Frédéric, Bouix, Jacques, Boissy, Alain

    The present study aimed to evaluate an experimental approach to individually assess social reactivity among sheep. INRA401 male lambs (n=163) were reared together outdoors as part of a larger flock. Fifteen days after weaning the animals were individually exposed to an arena test of 2 phases...

  8. Addressing pain caused by mulesing in sheep

    Contributor(s):: Fisher, Andrew 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...

  9. Acute effects of mulesing and alternative procedures to mulesing on lamb behaviour

    Contributor(s):: Edwards, Lauren E., Arnold, Naomi A., Butler, Kym L., Hemsworth, Paul H.

    The practice of surgical mulesing is used as a preventative measure against flystrike in sheep. However, this practice raises welfare concerns due to the severity of the wound and the pain inflicted. Alternative procedures to mulesing have been investigated, but few of these studies have...

  10. City of Beasts: How Animals Shaped Georgian London. Manchester: Manchester University Press, 2019. xviii + 310pp. 34 figures. Bibliography. £25.00 hbk. £30.00 ebk

    Contributor(s):: Taverner, Charlie

    Farm animals populate the next two sections: the cows and pigs reared within the built-up area, and the cattle and sheep driven into the heart of the city to be slaughtered. A recurrent theme of the book is the way in which urban growth actually increased interactions between animals and humans...

  11. 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...

  12. 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...

  13. 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...

  14. 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...

  15. Mother-offspring relationship in Morada Nova sheep bred in a tropical semiarid environment: A perspective on maternal investment and parental conflict

    Contributor(s):: Fonsêca, Vinícius F. C., Saraiva, Edilson P., Arruda, Maria F., Pereira, Walter E., Pimenta Filho, Edgard C., Santos, Severino G. C. G., Amorim, Mikael L. C. M., Silva, Josinaldo A.

    In 2011 and 2012, we investigated the mother-offspring relationship in 60 Morada Nova ewe-lamb pairs from lambing (August) until 40 d after lambing. In years 1 and 2, there were 28 and 32 multiparous ewes, 13 and 20 single male lambs, and 15 and 12 twin male lambs, respectively. The behavior of...

  16. 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...

  17. 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,...

  18. 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...

  19. 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...

  20. 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...
