  1. Development and consistency of fearfulness in horses from foal to adult

    Contributor(s):: Christensen, Janne Winther, Beblein, Carina, Malmkvist, Jens

    Understanding the development and consistency of behavioural responses across life stages is of both fundamental and applied interest. In horses, fearfulness is particularly important because fear reactions are a major cause of human-horse accidents, and because fear is a negative emotional state...

  2. The role of genes, epigenetics and ontogeny in behavioural development

    Contributor(s):: Rodenburg, T. Bas

    This review focuses on the role of genes, epigenetics and ontogeny in behavioural development of animals. The behavioural characteristics of an individual are determined by its genes and by its physical and social environment. Not only the individual's early life and current environment are of...

  3. Chewable materials before weaning reduce tail biting in growing pigs

    Contributor(s):: Telkänranta, Helena, Swan, Kirsi, Hirvonen, Heikki, Valros, Anna

    Tail biting in pigs is a multi-factorial problem, and the early rearing environment has been proposed as a potential previously unidentified factor. The aim of this study was to test whether access to chewable material from birth to weaning reduces later tail biting. Undocked litters of 59 sows...

  4. Can sow pre-lying communication or good piglet condition prevent piglets from getting crushed?

    Contributor(s):: Melišová, Michala, Illmann, Gudrun, Andersen, Inger Lise, Vasdal, Guro, Haman, Jiří

    This study focused on the impact of sow–piglet communication during pre-lying behaviour and piglet condition on piglet location before the sow was lying down and on the incidence of piglet crushing. Eighteen loose-housed, Yorkshire×Norwegian Landrace sows and their litters were studied on Day 1...

  5. Individual and group level trajectories of behavioural development in Border collies

    Contributor(s):: Riemer, Stefanie, Müller, Corsin, Virányi, Zsófia, Huber, Ludwig, Range, Friederike

    In order to assess dogs’ personality changes during ontogeny, a cohort of 69 Border collies was followed up from six to 18–24 months. When the dogs were 6, 12, and 18–24 months old, their owners repeatedly filled in a dog personality questionnaire (DPQ), which yielded five personality factors...

  6. A Tinbergian review of self-injurious behaviors in laboratory rhesus macaques

    Contributor(s):: Polanco, Andrea

    Self-injurious behaviors (SIBs) are a welfare and practical concern in laboratory rhesus macaques (Macaca mulatta), and may share a similar etiology to human SIBs. This review uses a Tinbergian perspective to investigate why rhesus monkeys perform SIBs. In addition to reviewing research...

  7. Behaviour of gilts before and at parturition after intensified human-animal contact, training to be driven, or exposure to a farrowing pen

    Contributor(s):: Brötje, Anska, Gygax, Lorenz, Hillmann, Edna, Wechsler, Beat

    During rearing and until first insemination, housing conditions of gilts are relatively constant and the few human-animal interactions negative. Around first parturition, however, gilts experience intensified contact with stockpersons and are subjected to new management procedures such as being...

  8. Human-directed behaviour in goats is not affected by short-term positive handling

    Full-text: Available

    | Contributor(s):: Jan Langbein, Annika Krause, Christian Nawroth

    In addition to domestication, interactions with humans or task-specific training during ontogeny have been proposed to play a key role in explaining differences in human–animal communication across species. In livestock, even short-term positive interactions with caretakers or other...

  9. Association between personality and stereotypic behaviours in the African striped mouse Rhabdomys dilectus

    | Contributor(s):: Joshi, Sneha, Pillay, Neville

    Stereotypic behaviours, which are abnormal, repetitive and invariant behaviours caused by frustration and/or central nervous system dysfunction, develop as a result of sub-optimal captive conditions that provide inadequate motor and sensory stimulation. However, not all individuals housed under...

  10. Individual hunting behaviour and prey specialisation in the house cat Felis catus: implications for conservation and management

    | Contributor(s):: Dickman, C. R., Newsome, T. M.

    Predators are often classed as prey specialists if they eat a narrow range of prey types, or as generalists if they hunt multiple prey types. Yet, individual predators often exhibit sex, size, age or personality-related differences in their diets that may alter the impacts of predation on...

  11. Dietary fatty acid composition significantly influenced the proactive-reactive behaviour of Senegalese sole ( Solea senegalensis) post-larvae

    | Contributor(s):: Ibarra-Zatarain, Z., Morais, S., Bonacic, K., Campoverde, C., Duncan, N.

    Few studies have examined the influence of diet on larval proactive-reactive behavioural dimension of stress coping style responses. The present study evaluated the influence of using different vegetables oils (Linseed; Soybean; Olive) and fish oil (Cod liver) for Artemia metanauplii nutritional...

  12. "Do not choose as I do!" - Dogs avoid the food that is indicated by another dog's gaze in a two-object choice task

    | Contributor(s):: Balint, A., Farago, T., Meike, Z., Lenkei, R., Miklosi, A., Pongracz, P.

    Family dogs successfully follow human-given cues in a two-object choice test. However, whether this ability has any roots in dog-dog visual communication, has been seldom investigated. We designed a test where a video-projected, life-sized dog 'demonstrator' provided directional cues for the...

  13. Ontogeny of daily activity and circadian rhythm in the Iberian lynx ( Lynx pardinus)

    | Contributor(s):: Yerga, J., Calzada, J., Manteca, X., Vargas, A., Perez, M. J., Palomares, F., Rivas, A.

    The aim of this paper is to describe the ontogeny of the circadian activity rhythms in captive-born Iberian lynx ( Lynx pardinus) from birth to subadult age and to verify if they develop a bimodal circadian pattern similar to the one they show in the wild. The amount of daily activity and the...

  14. A comparison of pet and purpose-bred research dog ( Canis familiaris) performance on human-guided object-choice tasks

    | Contributor(s):: Lazarowski, L., Dorman, D. C.

    Several studies have shown that domestic dogs respond to human social cues such as pointing. Some experiments have shown that pet dogs outperformed wolves in following a momentary distal point. These findings have lent support to the hypothesis that domestication is responsible for domestic dogs'...

  15. Contagious yawning in domestic dog puppies ( Canis lupus familiaris): the effect of ontogeny and emotional closeness on low-level imitation in dogs

    | Contributor(s):: Madsen, E. A., Persson, T.

    Contagious yawning is a well-documented phenomenon in humans and has recently attracted much attention from developmental and comparative sciences. The function, development and underlying mechanisms of the phenomenon, however, remain largely unclear. Contagious yawning has been demonstrated in...

  16. Can substrate in early rearing prevent feather pecking in adult laying hens?

    | Contributor(s):: Jong, I. C. de, Reuvekamp, B. F. J., Gunnink, H.

  17. Facial expressions modulate the ontogenetic trajectory of gaze-following among monkeys

    | Contributor(s):: Teufel, Christoph, Gutmann, Anke, Pirow, Ralph, Fischer, Julia

  18. Developmental instability and light regime in chickens ( Gallus gallus )

    | Contributor(s):: Moller, A. P., Sanotra, G. S., Vestergaard, K. S.

    Fluctuating asymmetry, a measure of developmental instability, was measured in 3 skeletal characters in chickens raised under 3 different lighting regimes: (A) a 16:8 light-dark cycle, (B) a changing light regime, and (C) permanent light. Chickens reared under permanent light developed 40% larger...

  19. Effects of feed- and water-based enrichment on activity and cannibalism in Muscovy ducklings

    | Contributor(s):: Riber, A. B., Mench, J. A.

    Cannibalism is a major problem for commercial production of Muscovy ducks (Cairina moschata). Surprisingly little is known about the ontogeny of cannibalism in ducks or how to reduce/prevent the problem in a welfare-friendly way. The preventative method typically used by the industry is...

  20. Social distances of goats at the feeding rack: influence of the quality of social bonds, rank differences, grouping age and presence of horns

    | Contributor(s):: Aschwanden, J., Gygax, L., Wechsler, B., Keil, N. M.

    To minimize social conflicts between goats and improve pen design, knowledge of factors affecting social distances at the feeding rack is needed. In our study, we investigated the influence of the quality of social bonds, rank differences, grouping age and presence of horns on two types of social...
