  1. The test-retest reliability of four behavioural tests of fearfulness for quail: a critical evaluation

    Contributor(s):: Miller, K. A., Garner, J. P., Mench, J. A.

    Tests of animal fearfulness are being used in a broad range of basic and applied scientific fields. However, rigorous assessment of the test-retest reliability of these tests is relatively uncommon. The importance of such assessment is illustrated by this study of the responses of Japanese quail...

  2. A note on the effects of co-mingling piglet litters on pre-weaning growth, injuries and responses to behavioural tests

    Contributor(s):: Kanaan, V. T., Pajor, E. A., Lay, D. C., Jr., Richert, B. T., Garner, J. P.

    The purpose of this study was to determine how co-mingling litters affected piglets' pre-weaning growth, ear injuries, suckling behaviour and responses to behavioural tests used to measure coping abilities. Thirty sows and their respective litters were housed in standard farrowing crates until...

  3. Factor analysis of behavioural tests in farmed silver and blue foxes

    Contributor(s):: Harri, M., Rekila, T., Mononen, J.

    The behaviour of farmed silver and blue foxes in the open-field were recorded and analysed with a computer-based system. In addition, the reaction towards humans and the capture time were recorded for animals in their home cage. Factor analysis with VARIMAX rotation produced four independent...

  4. Horses use procedural learning rather than conceptual learning to solve matching to sample

    Contributor(s):: Gabor, V., Gerken, M.

    Research into higher cognitive abilities of the horse may be limited by developing the adequate experimental design. In this study four pony mares between 8 and 19 years old were included. Three of them reached the criterion to be tested in a new design of matching to sample using a black circle...

  5. Using preference, motivation and aversion tests to ask scientific questions about animals' feelings

    Contributor(s):: Kirkden, R. D., Pajor, E. A.

    The past 30 years has seen an increased willingness for scientists to assess the subjective experiences of animals. There are good reasons to believe that domesticated animals are sentient beings, capable of having feelings. The study of feelings is central to the assessment of animal welfare....

  6. Characterising the emotional reactivity of cows to understand and predict their stress reactions to the slaughter procedure

    Contributor(s):: Bourguet, C., Deiss, V., Gobert, M., Durand, D., Boissy, A., Terlouw, E. M. C.

    The present study on 32 Normand cows evaluated whether it is possible to identify, during rearing, individuals likely to be relatively reactive to the slaughter procedure. It evaluated further which factors may contribute to stress during the pre-slaughter period. Behavioural and physiological...

  7. Development and application of a preference test system to evaluate housing conditions for laboratory rats

    Contributor(s):: Blom, H. J. M., Tintelen, G. van, Baumans, V., Broek, J. van den, Beynen, A. C.

    The preferences of rats for various heights and light intensities in cages were studied. Preferences were expressed as relative dwelling times (RDT) per cage. In the first experiment, using 9 female and 9 male Wistar rats, the females prefered lower cages (height 80 mm, RDT 29.9

  8. Effect of suckling ('restricted suckling') on dairy cows' udder health and milk let-down and their calves' weight gain, feed intake and behaviour

    | Contributor(s):: Froberg, S., Gratte, E., Svennersten-Sjaunja, K., Olsson, I., Berg, C., Orihuela, A., Galina, C. S., Garcia, B., Lidfors, L.

    The aim of this study was to evaluate the effects of restricted suckling (RS) in Holstein cattle on the weight gain, health and behaviour of calves and on udder health and milk let-down in cows compared to artificial rearing (AR). The study was conducted in Mexico. The 27 cows with calves were...

  9. Novel object test can detect marginal differences in environmental enrichment in pigs

    | Contributor(s):: Bracke, M. B. M., Spoolder, H. A. M.

    In search for a test measuring positive emotions in pigs for application in on-farm welfare auditing, three small experiments were conducted to examine the sensitivity of a novel object test designed to measure the pigs' (residual) need/motivation for enrichment. In the experiments the...

  10. The usefulness of grazing tests for studying the ability of sheep and cattle to exploit reproductive patches of pastures

    | Contributor(s):: Dumont, B., D'Hour, P., Petit, M.

    The grazing choices of heifers and ewes on cocksfoot (Dactylis glomerata) plots, half vegetative and half reproductive in area, with vegetative swards at 7 (T7), 11 (T11) or 18 cm (T18) were recorded over a whole day or during 30-min tests. Preferences were defined as the proportion of grazing...

  11. Social and individual components of animal contact in preschool children

    | Contributor(s):: Wedl, M., Kotrschal, K.

    Humans are generally biophilic. Still, for unknown reasons, interest in animals varies substantially among individuals. Our goal was to investigate how differential interest of children towards animals might be related to social competence and personality. We proposed two alternatives: (1)...

  12. A modified HET-CAM approach for biocompatibility testing of medical devices

    | Contributor(s):: Eder, C., Falkner, E., Mickel, M., Chiari-Grisar, C., Appl, H., Schoffl, H., Nehrer, S., Losert, U. M.

    The implantation of new biomedical devices into living animals without any previous toxicity or biocompatibility evaluation is possible under current legislation. The HET-CAM (Hen Egg Test-Chorionallantoic Membrane) test offers a partially immunodeficient, borderline in vitro/in vivo test system...

  13. Assessment of stress in non-human primates: application of the neutrophil activation test

    | Contributor(s):: Honess, P. E., Marin, C., Brown, A. P., Wolfensohn, S. E.

    A technique measuring leukocyte (neutrophil) activity was used to examine differences between stress levels in a breeding colony of rhesus macaques housed in either a traditional caging system or open-rooms. The leukocyte activation test measured the degree to which blood from the two treatment...

  14. Attitudes of farmers towards Limousin cattle and their handling

    | Contributor(s):: Boivin, X., Marcantognini, L., Boulesteix, P., Godet, J., Brule, A., Veissier, I.

    Farmers' behaviour towards their animals could be improved by developing training programmes designed to decrease handling stress and improve animal welfare. This requires key preliminary work to collate farmers' beliefs concerning beef cattle and their knowledge of how to handle them easily....

  15. Bridging consumer perception and on-farm assessment of animal welfare

    | Contributor(s):: Napolitano, F., Rosa, G. de, Caporale, G., Carlucci, A., Grasso, F., Monteleone, E.

    The present study aims to assess the relationship between consumer perception and on-farm assessment of animal welfare performed using the Animal Needs Index 35L (ANI). Two tie-stall, 2 straw yard and 2 cubicle farms were scored by trained assessors using the ANI and filmed to produce six 3.5 min...

  16. Can a modified Latency-to-Lie test be used to validate gait-scoring results in commercial broiler flocks?

    | Contributor(s):: Berg, C., Sanotra, G. S.

    Bodily contact with water is a novel and aversive experience for broiler chickens, and this has been used when designing the Latency to Lie (LTL) test. The original testing procedure, in which the birds are tested in groups, involves a certain settling period, which makes the test time-consuming...

  17. Mechanisms of decision-making and the interpretation of choice tests

    | Contributor(s):: Bateson, M.

    Choice tests are commonly used to measure animals' preferences, and the results of such tests are used to make recommendations regarding animal husbandry. An implicit assumption underlying the majority of choice tests is that the preferences obtained are independent of the set of options...

  18. An example of application of research in ethology from the horse's temperament tests and record of learning and behavior (LAC)

    | Contributor(s):: Lansade, L., Dubois, C., Gillot, A., Delfosse, A., Bon, M. le, Roche, H., Yvon, J. M., Foisnel, S., Rizo, S., Menard, C., Baumgartner, M., Vidament, M.

    The horse's behaviour strongly influences its suitability for riding activity. As professionals and amatory riders were interested by tests aimed at measuring the horse temperament, several scientific studies were conducted. From these studies, two sets of standardised tests were created: - the...
