  1. The importance of diet choice on stress-related responses by lambs

    Contributor(s):: Catanese, Francisco, Obelar, Marianela, Villalba, Juan J., Distel, Roberto A.

    Farm animals are commonly restricted to a reduced array of foods, like total mixed rations or pastures with low species diversity. Under these conditions, animals are less likely to satisfy their specific and changing nutrient requirements. In addition, foods and flavors eaten too frequently or...

  2. Exploring the dog park: Relationships between social behaviours, personality and cortisol in companion dogs

    Contributor(s):: Ottenheimer Carrier, Lydia, Cyr, Amanda, Anderson, Rita E., Walsh, Carolyn J.

    The relationships between behaviour, owner-rated personality, and cortisol were examined in companion dogs that visited a local off-leash dog park. In Study 1, salivary cortisol increased significantly from baseline levels following 20min in the dog park (P=0.013), but not in the same dogs...

  3. Effects of human contact and toys on the fear responses to humans of shelter-housed dogs

    Contributor(s):: Conley, Melanie J., Fisher, Andrew D., Hemsworth, Paul H.

    This study examined the effects of human contact and toys on fear responses to humans in small breed, shelter-housed dogs. Ninety dogs were assigned to one of three treatments: “control” (control), comprising routine husbandry performed by shelter staff; “human contact” (HC), where dogs...

  4. The effect of conspecific removal on the behaviour and physiology of pair-housed shelter dogs

    Contributor(s):: Walker, Jessica K., Waran, Natalie K., Phillips, Clive J. C.

    Dogs (Canis familiaris) are a highly social species and within a shelter environment pair-housing is recommended to prevent the stress associated with social isolation. Separation of individuals which may have formed bonds in this environment is a usual occurrence, as a result of rehoming or...

  5. Does housing nulliparous dairy cows with multiparous animals prior to calving influence welfare- and production-related parameters after calving?

    Contributor(s):: Boyle, Alastair R., Ferris, Conrad P., O’Connell, Niamh E.

    The aim of this experiment was to determine the effects of housing nulliparous cows with non-lactating multiparous cows during the pre-calving period, on welfare and production-related parameters during the post calving period. Twenty nulliparous Holstein Friesian dairy cattle were assigned to...

  6. 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...

  7. Cross sectional study comparing behavioural, cognitive and physiological indicators of welfare between short and long term kennelled domestic dogs

    Contributor(s):: Titulaer, Mieke, Blackwell, Emily J., Mendl, Michael, Casey, Rachel A.

    Affective states are an integral part of animal welfare but are difficult to assess using traditional welfare measurements. It has previously been shown that kennelled dogs commonly show indications of poor welfare. The aim of this study was to compare welfare of short-term (ST) and long-term...

  8. A comparison of welfare outcomes for weaner and mature Bos indicus bulls surgically or tension band castrated with or without analgesia: 2. Responses related to stress, health and productivity

    Contributor(s):: Petherick, J. Carol, Small, Alison H., Mayer, David G., Colditz, Ian G., Ferguson, Drewe M., Stafford, Kevin J.

    Tension banding castration of cattle is gaining favour because it is relatively simple to perform and is promoted by retailers of the banders as a humane castration method. Two experiments were conducted, under tropical conditions using Bos indicus bulls comparing tension banding (Band) and...

  9. Behavioural and physiological responses of domestic dogs (Canis familiaris) to agonistic growls from conspecifics

    Contributor(s):: Wood, Penney A., de Bie, Josine, Clarke, Jennifer A.

    Motivation–structural rule theory predicts that a sender producing harsh, low frequency sounds directed at a conspecific modifies the receiver's behaviour, in part, by communicating its willingness to escalate to an attack. Motivation–structural (MS) rules generally assume that receivers respond...

  10. Associations of behaviour with secretory immunoglobulin A and cortisol in domestic cats during their first week in an animal shelter

    Contributor(s):: Gourkow, Nadine, LaVoy, Alora, Dean, Gregg A., Phillips, Clive J. C.

    We tested the hypothesis that during their first week in an animal shelter, cats exhibit groups of behaviours that are connected to mucosal immune and adrenal responses. The behaviour of 34 cats was observed from admission to day 5 and immunoglobulin A (S-IgA) and cortisol were quantified from...

  11. Social transmission of physiological and behavioural responses to castration in suckling Merino lambs

    Contributor(s):: Colditz, Ian G., Paull, David R., Lee, Caroline

    In social species like sheep, social context can modify both physiological and behavioural responses to stressors and normal behavioural patterns. Presence of conspecifics can ameliorate responses to noxious stimuli, an effect termed social buffering, whereas the presence of a distressed...

  12. Selection for temperament in sheep: Domain-general and context-specific traits

    Contributor(s):: Beausoleil, Ngaio J., Blache, Dominique, Stafford, Kevin J., Mellor, David J., Noble, Alasdair D. L.

    Sheep at the University of Western Australia have been selectively bred for behavioral responses to isolation and human presence in an arena test, resulting in the creation of two divergent lines: More Active (MA) and Less Active (LA). The aim of this study was to determine whether selection was...

  13. Relationships between scores of the feline temperament profile and behavioural and adrenocortical responses to a mild stressor in cats

    Contributor(s):: Iki, Tazuko, Ahrens, Frank, Pasche, Katharina Hannah, Bartels, Angela, Erhard, Michael Helmut

    There is a growing need for an easy assessment of stress levels in cats in order to more effectively diagnose, distinguish and treat stress-related disorders or behavioural problems. Therefore, we investigated which behavioural changes might be associated with an adrenocortical response to an...

  14. A novel scale of behavioural indicators of stress for use with domestic horses

    Contributor(s):: Young, Tamsin, Creighton, Emma, Smith, Tessa, Hosie, Charlotte

    Behaviour scores (BS) offer non-invasive, objective and easy to use ways of assessing welfare in animals. Their development has, however, largely focused on behavioural reactions to stressful events (often induced), and little use of physiological measures has been made to underpin and validate...

  15. Individual differences in metabolism predict coping styles in fish

    Contributor(s):: Martins, Catarina I. M., Castanheira, Maria F., Engrola, Sofia, Costas, Benjamín, Conceição, Luís E. C.

    Studies on metabolism usually rely on measurements of oxygen consumption obtained in respirometry chambers. Despite rigorous standardization there is still considerable inter-individual variation in metabolic rates which is often ignored. Furthermore, housing in respirometry chambers implies...

  16. 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...

  17. Does structural enrichment for toxicology studies improve zebrafish welfare?

    Contributor(s):: Wilkes, Luanne, Owen, Stewart F., Readman, Gareth D., Sloman, Katherine A., Wilson, Rod W.

    Enrichment of the environment for captive animals is aimed at producing beneficial effects on the behaviour and physiology of relevant species, and is commonly used to reduce harmful social behaviours and stereotypies. However, little work has been undertaken to develop enrichment strategies for...

  18. A bio-behavioral study of chronic idiopathic colitis in the rhesus macaque (Macaca mulatta)

    Contributor(s):: Howell, Sue, White, Daniel, Ingram, Sonya, Jackson, Raven, Larin, Jorge, Morales, Pablo, Garcia, Ana Patricia, Hicks, Chassey, Hopper, Kelly, Wagner, Joseph

    This study focused on the bio-social factors that influence chronic idiopathic colitis (CIC) disease in rhesus macaques (Macaca mulatta). A retrospective study of CIC included all colony animals between 2007 and 2009. A prospective study included 36 rhesus macaques treated for CIC in 2008 and...

  19. Benefits of pair housing are consistent across a diverse population of rhesus macaques

    Contributor(s):: Baker, Kate C., Bloomsmith, Mollie A., Oettinger, Brooke, Neu, Kimberly, Griffis, Caroline, Schoof, Valérie, Maloney, Margaret

    Introducing singly housed rhesus macaques (Macaca mulatta) into isosexual pairs is widely considered to improve welfare. The population of laboratory rhesus macaques is heterogeneous on a variety of factors and there is little literature available to directly evaluate the influence of many of...

  20. Adolescents' Affective and Physiological Regulation Shape Negative Behavior During Challenging Equine Assisted Learning Activities

    Full-text: Available

    | Contributor(s):: Patricia Pendry, Alexa M. Carr, Jaymie L. Vandagriff

    This study examined associations between adolescents’ (N = 59; M age = 11.63) diurnal and momentary activity of the Hypothalamic Pituitary Adrenal (HPA) axis as marked by salivary cortisol, and affective and behavioral responses to their first, mounted equine assisted learning (EAL)...
