  3. Impact of inhalation anaesthesia, surgery and analgesic treatment on home cage behaviour in laboratory mice

    Contributor(s):: Cesarovic, Nikola, Arras, Margarete, Jirkof, Paulin

    Anaesthesia and analgesia are used frequently in laboratory routine to ensure animal welfare and good scientific outcomes in experiments that may elicit pain or require immobilisation of the animal. However, there is concern regarding the effect of these procedures on animal behaviour in...

  4. Immunocastration with Improvac™ reduces aggressive and sexual behaviours in male pigs

    Contributor(s):: Brewster, Veronica, Nevel, Amanda

    Surgical castration of male pigs is a common practice to reduce the risk of boar taint, an accumulation of pheromones in the muscles of pigs giving an undesirable odour to the pork of entire boars. Castration is not widely practiced in the UK for welfare reasons and indeed, assurance schemes will...

  5. I like my dog, does my dog like me?

    Contributor(s):: Rehn, Therese, Lindholm, Ulrika, Keeling, Linda, Forkman, Björn

    In this study, the possibility of there being an association between how an owner perceives his/her relationship to their dog and the way the dog experiences the relationship to its owner was investigated using two well-established methods within the anthrozoology literature. Twenty dog–owner...

  6. 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...

  7. Housing of female mice in a new environment and its influence on post-surgical behaviour and recovery

    Contributor(s):: Jirkof, Paulin, Cesarovic, Nikola, Rettich, Andreas, Arras, Margarete

    The transportation of mice into a new clean cage after surgery is a standard procedure but might have detrimental effects during the critical post-surgical recovery phase. To analyse the effect of post-surgical housing, female C57BL/6J mice housed in their familiar home cage or in a new...

  8. Genetic analysis of the individual pig behaviour in backtests and human approach tests

    Contributor(s):: Scheffler, K., Stamer, E., Traulsen, I., Krieter, J.

    The most recent development in pig production has focused increasingly on the well-being of the individual pig and animal-friendly housing conditions, i.e. the launch of the group housing of sows in the EU. In this regard, however, standard procedures which may be stressful to the animals and...

  9. First links between self-feeding behaviour and personality traits in European seabass, Dicentrarchus labrax

    Contributor(s):: Ferrari, Sébastien, Benhaïm, David, Colchen, Tatiana, Chatain, Béatrice, Bégout, Marie-Laure

    Most studies carried out with seabass under self-feeding conditions report an intriguing social structure that is built around the device and the food dispenser with three coexisting triggering categories: high-triggering (HT), low-triggering (LT) and zero-triggering (ZT) fish. However, neither...

  10. Environmental factors that affect the behavior and welfare of domestic cats (Felis silvestris catus) housed in cages

    Contributor(s):: Stella, Judi, Croney, Candace, Buffington, Tony

    Understanding environmental factors that affect the behavior of cats in cages is important if caretakers are to improve the welfare of confined cats. The aim of this study was to examine the effects of the macro (room) and micro (cage) environments on cat behavior and their implications for cat...

  11. Environmental enrichment and cognitive complexity in reptiles and amphibians: Concepts, review, and implications for captive populations

    Contributor(s):: Burghardt, Gordon M.

    Reptiles and amphibians have been neglected in research on cognition, emotions, sociality, need for enriched and stimulating environments, and other topics that have been greatly emphasized in work on mammals and birds. This is also evident in the historic lack of enriching captive environments...

  12. The enriching effect of non-commercial items in stabled horses

    Contributor(s):: Bulens, Anneleen, Van Beirendonck, Sanne, Van Thielen, Jos, Driessen, Bert

    The effect of the provision of simple objects to stabled horses on their behaviour was investigated to determine whether these objects can affect horses’ behaviour in a positive way and thus enrich their environment. A positive influence can for example be measured by a decrease in stereotypical...

  13. Effects of two substrate types on the behaviour, cleanliness and thermoregulation of dairy calves

    Contributor(s):: Sutherland, Mhairi A., Stewart, Mairi, Schütz, Karin E.

    The use of river stones as a substrate to rear calves on is a management practice that is becoming more common in parts of New Zealand where more traditional substrate types, such as sawdust, can be difficult and/or expensive to obtain. A study was conducted to compare the behaviour, cleanliness,...

  14. Effects of neonatal castration on social behaviour, human–animal relationship and feeding activity in finishing pigs reared in a conventional or an enriched housing

    Contributor(s):: Tallet, Céline, Brilloüet, Armelle, Meunier-Salaün, Marie-Christine, Paulmier, Valérie, Guérin, Carole, Prunier, Armelle

    Raising entire males is already common in a few European countries. It has the advantage of avoiding the pain of castration. Entire males have also a better food conversion. However, they would be more aggressive than castrates which causes welfare troubles. The consequences for human–animal...

  15. Effects of growth pattern and dietary protein level during rearing on feed intake, eating time, eating rate, behavior, plasma corticosterone concentration, and feather cover in broiler breeder females during the rearing and laying period

    Contributor(s):: van Emous, R. A., Kwakkel, René, van Krimpen, Marinus, Hendriks, Wouter

    An experiment was conducted to evaluate the effect of growth patterns (GP) and dietary crude protein levels (CP) during rearing (2–22 weeks of age) on feed intake, eating time, eating rate, behavior, plasma corticosterone concentration, and feather cover in broiler breeder females during the...
