  2. Associations between Domestic-Dog Morphology and Behaviour Scores in the Dog Mentality Assessment

    Full-text: Available

    | Contributor(s):: Holly R. Stone, Paul D. McGreevy, Melissa J. Starling, Bjorn Forkman

    The domestic dog shows a wide range of morphologies, that humans have selected for in the process of creating unique breeds. Recent studies have revealed correlations between changes in morphology and behaviour as reported by owners. For example, as height and weight decrease, many undesirable...

  3. Managing the Risk of Aggressive Dog Behavior: Investigating the Influence of Owner Threat and Efficacy Perceptions

    | Contributor(s):: Williams, E. J., Blackwell, E.

  4. Self-reports of Dutch dog owners on received professional advice, their opinions on castration and behavioural reasons for castrating male dogs

  5. Farmer Perceptions of Pig Aggression Compared to Animal-Based Measures of Fight Outcome

    Full-text: Available

    | Contributor(s):: Rachel S.E. Peden, Irene Camerlink, Laura A. Boyle, Faical Akaichi, Simon P. Turner

    Several animal welfare issues persist in practice despite extensive research which has been linked to the unwillingness of stakeholders to make changes. For example, most farmers do not perceive pig aggression to be a problem that requires action despite the fact that stress and injuries are...

  6. Social Behavior of a Reproducing Pair of the Philippine Tarsier (Tarsius syrichta) in Captivity

    | Contributor(s):: Wojciechowski, Filip J., Kaszycka, Katarzyna A., Řeháková, Milada

    Social interactions of the nocturnal primates are not well studied. One of the species for which social behavior is scarcely known is the Philippine tarsier (Tarsius [= Carlito] syrichta). We observed a reproducing pair of captive individuals over two mating seasons for two consecutive years. The...

  7. Prevailing Clusters of Canine Behavioural Traits in Historical US Demand for Dog Breeds (1926–2005)

    | Contributor(s):: Bethany Wilson, James Serpell, Harold Herzog, Paul McGreevy

    Drawing on American Kennel Club (AKC) puppy registration numbers for approximately 82 varieties of pedigree dogs between 1926 and 2005, the current article analyses behavioural reports on 32,005 dogs of these varieties reported through the Canine Behavioural Assessment and Research...

  8. Horse Matters: Re‐examining Sustainability through Human‐Domestic Animal Relationships

    | Contributor(s):: Wadham, Helen

  9. Pre-weaning socialization and environmental enrichment affect life-long response to regrouping in commercially-reared pigs

    | Contributor(s):: Ko, Heng-Lun, Chong, Qiai, Escribano, Damián, Camerlink, Irene, Manteca, Xavier, Llonch, Pol

    Weaning and other regrouping events as routine work in commercial farms cause stress to pigs and compromise their welfare. Several studies found positive outcomes to mitigate weaning stress when piglets were socialized (i.e. co-mingled) or raised with enrichment materials in research settings....

  10. Impact of a cattle brush on feedlot steer behavior, productivity and stress physiology

    | Contributor(s):: Park, Rachel M., Schubach, Kelsey M., Cooke, Reinaldo F., Herring, Andy D., Jennings, Jenny S., Daigle, Courtney L.

    The aim of the present study was to investigate the impact of environmental enrichment (EE), in the form of a cattle brush, on feedlot cattle behavior, productivity and stress physiology. Steers were blocked by weight and assigned to one of two treatments 1) Cattle brush secured to fence line...

  11. Effects of a temporary period on pasture on the welfare state of horses housed in individual boxes

    | Contributor(s):: Ruet, Alice, Arnould, Cécile, Levray, Justine, Lemarchand, Julie, Mach, Núria, Moisan, Marie-Pierre, Foury, Aline, Briant, Christine, Lansade, Léa

    Domesticated horses mainly live in individual boxes, a housing system reported as compromising animal welfare. A common practice in riding schools involves offering a temporary period on pasture with conspecifics to alleviate the impact of long-term deprivation triggered by boxes. The aim of this...

  12. Clinical and behavioural consequences of on-farm mixing of cull sows after weaning

    | Contributor(s):: Herskin, Mette S., Holm, Cathrine, Thodberg, Karen

    In modern pig production up to 50% of the sows are slaughtered each year. Typically, the period from the decision to cull and until a sow is slaughtered consists of a stay in an on-farm pick-up pen (hours to weeks), transport (eventually passing buying stations or similar) and lairage. However,...

  13. Behavioral and Perceptual Differences between Sexes in Dogs: An Overview

    Full-text: Available

    | Contributor(s):: Anna Scandurra, Alessandra Alterisio, Anna Di Cosmo, Biagio D’Aniello

    In this paper, we review the scientific reports of sex-related differences in dogs as compared to the outcomes described for wild animals. Our aim was to explore whether the differences in male and female dogs were affected by the domestication process, in which artificial selection is the main...

  14. Improving the Welfare of a Zoo-Housed Male Drill (Mandrillus leucophaeus poensis) Aggressive Toward Visitors

    | Contributor(s):: Martín, Olga, Vinyoles, Dolors, García-Galea, Eduardo, Maté, Carmen

    Improving the welfare of nonhuman animals in captivity and maintaining behavioral competence for future conservation purposes is of the highest priority for zoos. The behavior of an aggressive male drill (Mandrillus leucophaeus poensis) was assessed in Barcelona Zoo. The 2-year study presented in...

  15. Gibbon Aggression During Introductions: An International Survey

    | Contributor(s):: Harl, Heather, Stevens, Lisa, Margulis, Susan W., Petersen, Jay

    Little is known regarding the prevalence of aggression seen during introductions of captive gibbons (Hylobatidae). In this study, an online survey was developed to quantify and collect contextual details regarding the frequency and types of aggression seen during introductions of captive gibbons...

  16. Cruelty to Animals in Turkish Children: Connections with Aggression and Empathy

    | Contributor(s):: Akdemir, Seda, Gölge, Zeynep Belma

    This study explored the relationship between cruelty to animals, aggression, and empathy in primary school children. The relationship between pet ownership, love for animals in the family, and engaging in cruelty to animals was also investigated. The sample consisted of 1,248 students (633 girls,...

  17. Size does matter: The effect of enclosure size on aggression and affiliation between female New Zealand White rabbits during mixing

    | Contributor(s):: Valuska, Annie J., Mench, Joy A.

    Social enrichment is increasingly employed to improve the welfare of laboratory animals, including rabbits. However, the high levels of injurious aggression that can occur when unfamiliar adult rabbits are introduced to one another are a barrier to implementing social housing. One factor that...

  18. Measuring chronic social tension in groups of growing pigs using inter-individual distances

    | Contributor(s):: Turner, Simon P., Nath, Mintu, Horgan, Graham W., Edwards, Sandra A.

    Chronic social stress in pigs compromises immune function, reduces ADG, increases activity and skin lesions and affects feeding behaviour but to different extents in individuals and contemporary groups housed in the same way. Assessing the animals’ perception of chronic social stress is...

  19. Linking cortisol responsiveness and aggressive behaviour in gilthead seabream Sparus aurata: Indication of divergent coping styles

    | Contributor(s):: Castanheira, Maria Filipa, Herrera, Marcelino, Costas, Benjamín, Conceição, Luís E. C., Martins, Catarina I. M.

    Farmed animals, including fish, often exhibit a pronounced individual variation in stress coping styles with proactive and reactive individuals differing in a variety of neuroendocrine and behavioural responses. In this study we disclosed that individual differences in cortisol responsiveness...

  20. Lateralization of agonistic and vigilance responses in Przewalski horses (Equus przewalskii)

    | Contributor(s):: Austin, N. P., Rogers, L. J.

    Eye and limb preferences were scored in the closest undomesticated relative of Equus caballus using the same methods as used previously to study laterality in feral horses. Observations were made of 33 Przewalski horses (Equus ferus przewalskii) (male N=20, female N=13) living under natural...
