  1. Validating the use of a carbon dioxide laser for assessing nociceptive thresholds in adult domestic cats (Felis catus)

    Contributor(s):: Farnworth, Mark J., Beausoleil, Ngaio J., Adams, Nigel J., Barrett, Lorelle A., Stevenson, Mark, Thomas, David G., Waterland, Mark R., Waran, Natalie K., Stafford, Kevin J.

    Thermal sensitivity in cats has historically been assessed using complex devices which require direct application to the patient and can therefore, in themselves, affect the measurement. This study aimed to validate the use of a remote low power (165mW) carbon dioxide laser device for the...

  2. Repeatability and reliability of scores from ridden temperament tests conducted during performance tests

    Contributor(s):: König v. Borstel, Uta, Pirsich, Wiebke, Gauly, Matthias, Bruns, Erich

    Current scores for equine personality traits assessed during performance tests are characterised by high means and inadequate variation, hampering genetic selection for these traits. A number of temperament and related behaviour tests have been developed in order to make assessment of equine...

  3. Consistency of individual variation in feeding behaviour and its relationship with performance traits in Nile tilapia Oreochromis niloticus

    Contributor(s):: Martins, Catarina I. M., Conceição, Luis E. C., Schrama, Johan W.

    Feed intake is commonly used as one of the most important performance indicators in fish. However, very little is known about the behavioural processes involved in ingesting food such as meal duration, feeding frequency and latency to start eating. This study aims at the characterization of...

  4. Subjective methods to quantify temperament in beef cattle are insensitive to the number and biases of observers

    Contributor(s):: Parham, Jamie T., Tanner, Amy E., Wahlberg, Mark L., Grandin, Temple, Lewis, Ronald M.

    Associations between excitable temperament and many economically relevant traits have been established, resulting in an increased focus on docility in breeding programs in cattle. Several methods have been proposed to quantify temperament during normal handling procedures, which appear to differ...

  5. The backtest in pigs revisited - an analysis of intra-situational behaviour

    Contributor(s):: Zebunke, M., Repsilber, D., Nurnberg, G., Wittenburg, D., Puppe, B.

    The occurrence of different behavioural phenotypes in animals (regarding temperament and personality) has increasingly attracted the attention of scientists dealing with farm animal breeding, management and welfare. As part of the adaptation repertoire, coping behaviour describes how animals deal...

  6. Consistency in European seabass coping styles: a life-history approach

    Contributor(s):: Ferrari, S., Millot, S., Leguay, D., Chatain, B., Begout, M. L.

    Recent years have seen a growth of interest in the consistent differences in individual behaviour over time and contexts constituting the so-called "individual coping styles". An understanding of this inter-individual variation is essential to improve our knowledge of the adaptive value of...

  7. A study on validity and reliability of on-farm tests to measure human-animal relationship in horses and donkeys

    Contributor(s):: Costa, E. dalla, Dai, F., Murray, L. A. M., Guazzetti, S., Canali, E., Minero, M.

    The development and maintenance of a positive human-horse/donkey relationship is essential in order to decrease accidents and reduce negative states of equine welfare. In many animal species the reaction of animals to humans during specific behavioural tests is influenced by their past...

  8. Comparison of locomotion scoring for dairy cows by experienced and inexperienced raters using live or video observation methods

    Contributor(s):: Schlageter-Tello, A., Bokkers, E. A. M., Koerkamp, P. W. G. G., Hertem, T. van, Viazzi, S., Romanini, C. E. B., Halachmi, I., Bahr, C., Berckmans, D., Lokhorst, K.

    Lameness is considered a major problem in dairy production. Lameness is commonly detected with locomotion scores assigned to cows under farm conditions, but raters are often trained and assessed for reliability and agreement by using video recordings. The aim of this study was to evaluate intra-...

  9. Evaluating the effect of semi-group housing of rabbit does on their offspring's fearfulness: can we use the open-field test?

    Contributor(s):: Buijs, S., Tuyttens, F. A. M.

    Breeding does are usually housed one doe per cage, but there is an increased interest in (semi-)group housing systems designed to improve welfare. However, there is a lack of information on how such systems actually affect different aspects of rabbit welfare. We aimed to discern differences in...

  10. A training programme to ensure high repeatability of injury scoring of dairy cows

    Contributor(s):: Gibbons, J., Vasseur, E., Rushen, J., Passille, A. M. de

  11. Inter- and intra-observer reliability of experienced and inexperienced observers for the Qualitative Behaviour Assessment in dairy cattle

    Contributor(s):: Bokkers, E. A. M., Vries, M. de, Antonissen, I. C. M. A., Boer, I. J. M. de

  12. Comparison of methods to assess fear of humans in sows

    Contributor(s):: Scott, K., Laws, D. M., Courboulay, V., Meunier-Salaun, M. C., Edwards, S. A.

    The aims of this study were to compare three different methods to assess fear of humans in sows, and identify the most practical and reliable method for on-farm welfare assessment. Fifty-five crossbred sows (Landrace x Large White x Duroc) of different parities and stages of pregnancy were each...

  13. Nursing behaviour of sows during 5 weeks lactation and effects on piglet growth

    Contributor(s):: Valros, A. E., Rundgren, M., Spinka, M., Saloniemi, H., Rydhmer, L., Algers, B.

    The main goal of this study was to investigate the effect of sow nursing behaviour on piglet liveweight gain and within-litter variation (WLV) in piglet liveweight gain under as naturalistic conditions as possible. In order to achieve this, patterns of sow nursing behaviour and piglet liveweight...

  14. Reliability and inter-test relationship of tests for on-farm assessment of dairy cows' relationship to humans

    Contributor(s):: Windschnurer, I., Schmied, C., Boivin, X., Waiblinger, S.

    Animals' relationship to humans, i.e., their perception of humans, is an important parameter to be included into on-farm welfare assessment schemes. The objectives of this study were to evaluate inter-observer reliability and between-experimenter repeatability of three previously used and two new...

  15. Reliability of an avoidance distance test for the assessment of animals' responsiveness to humans and a preliminary investigation of its association with farmers' attitudes on bull fattening farms

    Contributor(s):: Windschnurer, I., Boivin, X., Waiblinger, S.

    In many farm animal species, the relationship to humans affects their welfare considerably. But until now, on-farm studies on fattening bulls have been limited. A feasible, reliable methodology for assessing responses of bulls to humans would be helpful for large scale surveys on this topic....

  16. Repeatability and reliability of an approach test to determine calves' responsiveness to humans: "a brief report"

    Contributor(s):: Lensink, B. J., Reenen, C. G. van, Engel, B., Rodenburg, T. B., Veissier, I.

    A test aiming to measure calves' responses to humans ("approach test") was conducted in two steps: during the first step (approach phase) the calves' reaction to the appearance of an unknown person (withdrawal or not) was observed during milk provision, during the second step (touch phase) the...

  17. Consistency of aggressive feeding behaviour in dairy cows

    Contributor(s):: Gibbons, J. M., Lawrence, A. B., Haskell, M. J.

    This study tests the two main characteristics of a temperament trait, consistency across time and consistency across situations. The temperament trait of interest was aggressiveness during feeding in dairy cattle. In this study, we focused on whether it is possible to infer a trait of...

  18. Reliability of assessment of dogs' behavioural responses by staff working at a welfare charity in the UK

    Contributor(s):: Diesel, G., Brodbelt, D., Pfeiffer, D. U.

    Behavioural problems in dogs are a major cause for their relinquishment and return to animal shelters and rehoming centres. It is important that the staff in these welfare centres can reliably assess the behavioural characteristics of the dogs so that they can be rehomed to the most appropriate...

  19. Reliability of temperament tests on finishing pigs in group-housing and comparison to social tests

    Contributor(s):: Brown, J. A., Dewey, C., Delange, C. F. M., Mandell, I. B., Purslow, P. P., Robinson, J. A., Squires, E. J., Widowski, T. M.

    If variation in behaviour is consistent within individuals and reliably associated with relevant welfare measures, this variation could aid in genetic selection, or development of management schemes designed to improve welfare. In this study, we focused on temperament tests in group-housed...

  20. Responsiveness of dairy cows to human approach and novel stimuli

    Contributor(s):: Gibbons, J., Lawrence, A., Haskell, M.

    This study investigated intra-test and inter-test consistency of dairy cattle behavioural responses to a series of tests involving human approach and exposure to novelty. Thirty-six lactating Holstein-Friesian cows were each subjected to three human approach tests and three novel stimuli tests....
