    Contributor(s):: Wadham, Helen

  3. 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....

    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...

  5. 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...

  6. 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,...

  7. 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...

  8. 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...

  9. 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...

  10. 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,...

  11. 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...

  12. 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...

  13. 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...

  14. 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...

  15. Interaction between sows’ aggressiveness post mixing and skin lesions recorded several weeks later

    | Contributor(s):: Tönepöhl, Björn, Appel, Anne K., Voß, Barbara, König von Borstel, Uta, Gauly, Matthias

    Group housing of pigs leads inevitably to more or less serious agonistic interactions during the establishment of the social rank order of the group. In order to reduce the number of severe agonistic interactions and thus the negative effects on well-being and performance, the use of genetic...

  16. Human directed aggression in domestic dogs (Canis familiaris): Occurrence in different contexts and risk factors

    | Contributor(s):: Casey, Rachel A., Loftus, Bethany, Bolster, Christine, Richards, Gemma J., Blackwell, Emily J.

    The consequence for dogs of showing aggression towards people is often euthanasia or relinquishment. Aggression is also a sign of compromised welfare in dogs, and a public health issue for people. The aims of this study were to estimate the numbers of dogs showing aggression to people in three...

  17. Hierarchy formation in newly mixed, group housed sows and management strategies aimed at reducing its impact

    | Contributor(s):: Greenwood, Emma C., Plush, Kate J., van Wettere, William H. E. J., Hughes, Paul E.

    Aggression is at its highest when sows are first introduced to new animals and hierarchies are being established. Thus, methods to reduce aggression should focus on this period. The aggression that occurs during mixing results in physiological stress responses, which can have detrimental effects...

  18. Effect of hiding places, straw and territory on aggression in group-housed rabbit does

    | Contributor(s):: Rommers, Jorine M., Reuvekamp, Berry J. F., Gunnink, Henk, de Jong, Ingrid C.

    Group-housing of rabbit does may be preferred from welfare point of view. However, group-housing causes agonistic behaviour which may cause severe injuries. Severe injuries may be prevented by offering hiding places for attacked does. Providing enrichment (straw) may reduce agonistic behaviour by...

  19. Chimpanzees use multiple strategies to limit aggression and stress during spatial density changes

    | Contributor(s):: Duncan, Luke Mangaliso, Jones, Megan Anne, van Lierop, Mathew, Pillay, Neville

    The regulation of aggression in captive animals is an important welfare concern. Captive environments typically provide limited space for animals and many species exhibit heightened aggression in response to spatial restriction. However, primates appear to regulate aggression under these...

  20. Bite marks in mink—Induced experimentally and as reflection of aggressive encounters between mink

    | Contributor(s):: Hansen, Steffen W., Møller, Steen H., Damgaard, Birthe M.

    For many years, bite marks have been used as an indicator for aggression in mink production systems. However, the validity of bite marks as indicator of aggression has recently been questioned. We therefore tested the following hypotheses: (1) experimentally applied pressure to, or penetration...
