  1. 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...

  2. Effect of pre-weaning temporary isolation within different age periods on the early post-weaning behaviour of juvenile lambs

    Contributor(s):: Simitzis, Panagiotis, Petrou, Miria, Demiris, Nikos, Deligeorgis, Stelios

    Temporary maternal separation is a stressful situation typical under modern husbandry practices and may have an undesirable impact on lamb welfare. However, at present there is insufficient evidence on temporary maternal separation effects on the behaviour of juvenile lambs. The aim of the...

  3. Interaction with a bovine cortical bone in the Finnraccoon (Nyctereutes procyonoides ussuriensis)

    Contributor(s):: Koistinen, Tarja, Sepponen, Juhani, Korhonen, Hannu T.

    Finnraccoons (Nyctereutes procyonoides ussuriensis) are farmed for their fur. The welfare of Finnraccoons in the current housing conditions has not been thorough documented. The aim of the present study is to measure the juvenile Finnraccoons’ interaction with a commonly used activity object,...

  4. Unpredictability in food supply during early life influences growth and boldness in European seabass, Dicentrarchus labrax

    Contributor(s):: Sébastien, Ferrari, Leguay, Didier, Vergnet, Alain, Vidal, Marie-Odile, Chatain, Béatrice, Bégout, Marie-Laure

    Biological variability is no longer considered as statistical noise, but rather as an adaptive benefit. This variability comes from consistent differences in behavioral and physiological responses among individuals to a changing/challenging environment, named “coping style”, “temperament” or...

  5. Juvenile Finnraccoons (Nyctereutes procyonoides ussuriensis) choose to allohuddle on the cage floor instead of resting on a platform

    Contributor(s):: Koistinen, Tarja, Korhonen, Hannu T.

    Comfort around resting is one of the key factors affecting farm animal welfare. The aim of the present study is to document the resting preferences in the Finnraccoon (Nyctereutes procyonoides ussuriensis) with special attention to the use of a platform. Sixteen sister-pairs of Finnraccoons were...

  6. Prevalence of stereotypies and its possible causes among captive Asian elephants ( Elephas maximus) in Tamil Nadu, India

    Contributor(s):: Vanitha, Varadharajan, Thiyagesan, Krishnamoorthy, Baskaran, Nagarajan

    Animals in captivity are often confined in small barren enclosures, preventing adequate exercise, and socialization with conspecifics. Captivity is also known for depriving young individuals' association with maternal relatives by weaning away from their mothers' earlier than what their peers...

  7. Behavioural consequences of visual deprivation occurring at hatch or in the early life of chickens

    Contributor(s):: Hocking, P. M., Haldane, K. A., Davidson, E. M., Sandoe, P., Kristensen, H. H.

    The development of behaviour in a line of chickens that are born sighted ( rdd) but turn blind after hatching was compared with a line that is blind at hatch ( beg) and with sighted White Leghorn controls (WL) to test the hypothesis that birds that become blind later in their life will show...

  8. Overview and critique of stages and periods in canine development

    Contributor(s):: Fox, M. W.

  9. Measuring motivation in swine: the food-metric scale

    Contributor(s):: Patterson-Kane, E. G., Kirkden, R. D., Pajor, E. A.

    Understanding how nonhuman animals such as swine respond to their environment and understanding how to provide them with a good quality of life involves using a range of experimental approaches. More and more, ethological researchers are turning to operant methods to answer some of these...

  10. The effects of husbandry training on stereotypic pacing in captive African wild dogs ( Lycaon pictus )

    Contributor(s):: Shyne, A., Block, M.

    To examine the effects of operant conditioning on stereotypic pacing in 3 female African wild dogs located at the Franklin Park Zoo in Boston, this study made recordings of pacing behavior immediately following individual sessions of husbandry training and 2 no-training conditions. The study...

  11. Shedding ultraviolet light on welfare in laboratory rodents: suggestions for further research and refinement

    Contributor(s):: Sorensen, D. B.

    The welfare of laboratory rats and mice is sought to be optimised through adjustment of a variety of environmental factors, including light intensity and photoperiodicity. However, the fact that rodents are able to perceive ultraviolet (UV) light tends to be ignored. The importance of being able...

  12. Effects on bereavement using a restricted sensory environment (psychomanteum)

    Contributor(s):: Hastings, Arthur

  13. Effects of developmental history on the behavioural responses of European starlings ( Sturnus vulgaris) to laboratory husbandry

    Contributor(s):: Jayne, K., Feenders, G., Bateson, M.

  14. Pet ownership, dog types and attachment to pets in 9-10 year old children in Liverpool, UK

  15. Influence of visual experience deprivation on the postnatal development of the microvascular bed in layer IV of the rat visual cortex

    | Contributor(s):: Argandoña, Enrike G., Lafuente, Jose V.

  16. Bones as enrichment for farmed blue foxes ( Vulpes lagopus ): interaction with the bones and preference for a cage with the bones

    | Contributor(s):: Koistinen, T., Turunen, A., Kiviniemi, V., Ahola, L., Mononen, J.

    Animal welfare regulations (e.g. Recommendations of European Convention) state that farmed foxes need to be provided with an activity object, though the material or shape of the object is not specified. We aimed to evaluate the properties of bones as an activity object for farmed blue foxes...

  17. Discriminating among novel foods: effects of energy provision on preferences of lambs for poor-quality foods

    | Contributor(s):: Villalba, J. J., Provenza, F. D.

    A study was conducted to better understand how lambs discriminate among novel foods based on flavour and post-ingestive effects. The manner in which temporal sequence of food ingestion and post-ingestive feedback affected preference when lambs were fed flavoured wheat straw (a poorly nutritious...

  18. Eye white may indicate emotional state on a frustration-contentedness axis in dairy cows

    | Contributor(s):: Sandem, A. I., Braastad, B. O., Boe, K. E.

    Research on welfare indicators has focused primarily on indicators of poor welfare, but there is also a need for indicators that can cover the range from good to poor welfare. The aim of this experiment was to compare behaviour elements in dairy cows shown in response to a frustrative situation...

  19. How important is shade to dairy cattle? Choice between shade or lying following different levels of lying deprivation

    | Contributor(s):: Schutz, K. E., Cox, N. R., Matthews, L. R.

    Provision of shade to dairy cattle in summer can alleviate negative effects of heat stress. The aim of this study was to investigate the relative importance of shade to lactating dairy cows in different ambient weather conditions in summer. The motivation to use shade was compared to the...

  20. Preventing physical interactions between parturient ewes and their neonate differentially impairs the development of maternal responsiveness and selectivity depending on maternal experience

    | Contributor(s):: Otal, J., Levy, F., Cornilleau, F., Moussu, C., Keller, M., Poindron, P.

    The present study investigated whether deprivation of nursing or of any physical interaction with the lamb impairs the onset of maternal responsiveness and the establishment of selectivity in primiparous and multiparous ewes. Just after parturition, ewes could interact freely with their lamb, or...
