  1. Intraspecific relationships in adult domestic dogs (Canis familiaris) living in the same household: A comparison of the relationship with the mother and an unrelated older female dog

    Contributor(s): Diane Lefebvre, Claire Diederich, Madeleine Delcourt, Jean-Marie Giffroy

    There is scientific evidence that adult dogs establish attachment bonds towards human beings. Attachment as behavioural system exists in the puppy-mother relationship, but adult dogs tested with the Ainsworth Strange Situation Test (ASST) have been found to show a preference for the stranger over...

  2. Indoor side fidelity and outdoor ranging in commercial free-range chickens in single- or double-sided sheds

    The ranging behaviour of broiler chickens kept in free-range housing systems remains poorly understood, despite access to the outdoor range being their main feature. We investigated the impact of allowing chickens to have range access on both sides vs. one side of the shed, using 24 flocks of...

  3. Effects of group size on behaviour, growth and occurrence of bite marks in farmed mink

    The aims of this study were to investigate the occurrence of stereotypic behaviours and the activity level in farmed mink when group housed in climbing cages and if group housing increase aggression by assessing the prevalence of bite marks. This was studied in juvenile mink of the colour types...

  4. Gradual weaning during an extended lactation period improves performance and behavior of pigs raised in a multi-suckling system

    We studied effects of two weaning procedures on the development of pigs raised in a multi-suckling (MS) system with five sows and their litters. One MS group was subjected to a gradual weaning treatment during a lactation period of 9 wk, which included forced intermittent-suckling (IS) for 10h/d...

  5. Behaviour, stress and welfare of Sprague Dawley rats (Rattus norvegicus) on diet board feeding for 24 months

    Diet board (DB) feeding aims to reduce the health hazards associated with ad libitum (AL) feeding. Rats have to gnaw wood to detach food from the DB, reducing their food consumption. We studied the welfare effects of DB by measuring faecal corticosterone metabolites (FCM), elevated plus-maze...

  6. Behavioural response of dairy goat kids to cautery disbudding

    Behavioural changes associated with cautery disbudding of female Saanen dairy goat kids were assessed. At 4±2days of age, kids were randomly assigned to one of two treatment groups: (i) disbudded with a cautery iron (CAUT, n=5) and (ii) sham handled and not disbudded (SHAM, n=5). Animals were...

  7. Behavior changes associated with lameness in sows

    Lameness is a common health and welfare problem in sows. Little has been published about behavioral changes in lame sows. Ketoprofen is an effective non-steroidal anti-inflammatory drug used to treat non-infectious locomotor disorders in pigs. The aim of this study was to determine the effect of...

  8. Effects of confinement duration and parity on behavioural responses and the degree of psychological fear in pregnant sows

    The aim of this study was to evaluate the effects of space restriction stress on the behavior of different parity sows, and it is necessary to understand such effects due to space restriction to improve the welfare of the sows in confined conditions. We selected 264 pregnant sows (Large White) at...

  9. Emotional states and emotional contagion in pigs after exposure to a positive and negative treatment

    After-effects of events that elicit an emotional state on both the animals that experienced these events and on their group members have only scarcely been studied. We investigated effects of a positive vs. negative treatment on the behaviour and emotional state of pigs and their naive pen mates...

  10. Social bonds in a flock bird: Species differences and seasonality in social structure in captive flamingo flocks over a 12-month period

    Social network analysis (SNA) is a popular tool for investigating key components of sociality in free-living populations, and is growing in its application to captive animal systems. For social species held in captivity, welfare may be improved if protocols for care take key aspects of sociality...

  11. Persistence of food guarding across conditions of free and scheduled feeding in shelter dogs

    Contributor(s): Diane Lefebvre, Claire Diederich, Madeleine Delcourt, Jean-Marie Giffroy

    The hypothesis that free access to food might reduce food-related aggression in shelter dogs was tested. Dogs that exhibited food-related aggression in a standardized assessment (ASPCA SAFER®) were provided either unlimited access to food or two scheduled daily feedings for 3days (Groups A and B)...

  12. Evaluation of an aversion-based program designed to reduce predation of native birds by dogs: An analysis of training records for 1156 dogs

    Contributor(s): Diane Lefebvre, Claire Diederich, Madeleine Delcourt, Jean-Marie Giffroy

    The aim of this study was to quantify 1647 aversion training sessions involving 1156 dogs conducted between 1998 and 2007 at Coromandel sites (North Island, New Zealand). The effects of gender, age, social group size, function of dog, breed, number of training sessions and responses to training...

  13. The application of learning theory in horse training

    The millennia-old practices of horse training markedly predate and thus were isolated from the mid-twentieth century revelation of animal learning processes. From this standpoint, the progress made in the application and understanding of learning theory in horse training is reviewed including a...

  14. Indicators of stress in equitation

    Stress is a generic concept describing the body’s reaction to external stimuli, including both physiological and psychological factors. Therefore, by definition, the assessment of psychological stress in the exercising horse encompasses the problem of teasing apart the psychological and...

  15. Application of learning theory in horse rescues in England and Wales

    In England and Wales the welfare of animals, including horses, is protected by the Animal Welfare Act 2006. Welfare agencies play a role in the investigation of equine welfare concerns and catching, containing, transporting and boarding (caring for) horses that have been rescued. Horses regularly...

  16. Applied neurophysiology of the horse; implications for training, husbandry and welfare

    Understanding the neural circuits underlying equine behaviour has the potential to help optimise strategies of husbandry and training. This review discusses two areas of neurophysiological research in a range of species and relates this information to the horse. The first discussion focuses on...

  17. The role of the ethogram in equitation science

    The development of a comprehensive ethogram that could be used to record the behaviour of the ridden horse in a range of different scenarios would provide a valuable resource for researchers within equitation science. However, the relevance of the behaviours included in such an ethogram and...

  18. Chimpanzees with positive welfare are happier, extraverted, and emotionally stable

    Facilities housing captive animals are full of staff who, every day, interact with the animals under their care. The expertise and familiarity of staff can be used to monitor animal welfare by means of questionnaires. It was the goal of our study to examine the association between chimpanzee (Pan...

  19. Effectiveness of verbal and gestural signals and familiarity with signal-senders on the performance of working dogs

    Contributor(s): Diane Lefebvre, Claire Diederich, Madeleine Delcourt, Jean-Marie Giffroy

    We assessed how highly trained dogs respond to gestural versus verbal signals when their handlers or an unfamiliar person asked them to perform an obedience task. Dogs were requested to perform four different actions (“Sit”, “Down”, “Stay” and “Come”) upon receiving congruent (only gestural or...

  20. Effect of sex and gonadectomy on dogs’ spatial performance

    Contributor(s): Diane Lefebvre, Claire Diederich, Madeleine Delcourt, Jean-Marie Giffroy

    In order to investigate the effect of sex and gonadectomy on dog’s spatial performance, 64 pet dogs were recruited until obtaining four equally sized groups, namely intact males (IM), orchiectomised males (OM), intact females (IF) and ovariectomised females (OF). Dogs were tested in a T-maze...
