  1. What can kinematics tell us about the affective states of animals?

    Contributor(s):: Guesgen, M. J., Bench, C. J.

  2. Test-retest reliability and predictive validity of a juvenile guide dog behavior test

    Full-text: Available

    | Contributor(s):: Harvey, N. D., Craigon, P. J., Sommerville, R., McMillan, C., Green, M., England, G. C. W., Asher, L.

    The ability to measure stable and consistent behavioral traits in dogs would facilitate selection and assessment of working dogs, such as guide dogs. Ideally, these measures should predict suitability for the working role from a young age. This study assessed test-retest reliability of a...

  3. Effects of growth-promoting technology on feedlot cattle behavior in the 21 days before slaughter

    | Contributor(s):: Stackhouse-Lawson, K. R., Tucker, C. B., Calvo-Lorenzo, M. S., Mitloehner, F. M.

    There is growing interest in the animal welfare implications of growth-promoting technology used in feedlot cattle, namely hormonal implants, ionophores, antibiotics and β 2-adrenergic agonists. Previous studies have focused on the effects of implants on aggression, but little work has...

  4. Effect of enclosure size and complexity on the behaviors of captive chimpanzees ( Pan troglodytes )

    | Contributor(s):: Jensvold, M. L. A., Sanz, C. M., Fouts, R. S., Fouts, D. H.

    Reports describing the implementation of innovative facility designs are important to both the primate caregiving community and policymakers reviewing current U.S. Department of Agriculture regulations. This study documents the changes in behaviour of 5 adult chimpanzees that coincided with...

  5. What is the relationship between level of infection and 'sickness behaviour' in cattle?

    | Contributor(s):: Szyszka, O., Kyriazakis, I.

  6. Behavioural responses of juvenile steller sea lions to abdominal surgery: developing an assessment of post-operative pain

    | Contributor(s):: Walker, K. A., Horning, M., Mellish, J. A. E., Weary, D. M.

    Marking and tracking of marine mammals is required to gain a better understanding of life history traits; however, some marking procedures used are likely painful. Recent technological advances include intra-abdominally implanted archival telemetry devices for the life-long monitoring of...

  7. Characterisation of sows' postures and posture changes with regard to crushing piglets

    | Contributor(s):: Wischner, D., Kemper, N., Stamer, E., Hellbruegge, B., Presuhn, U., Krieter, J.

    The aim of this study was to analyse different behavioural traits of sows to describe posture changes and to determine the influences of these traits on piglet losses. The behaviour of 386 German Landrace sows (with 438 pure-bred litters) was videotaped continuously starting 12 h prepartum until...

  8. Effect of caustic paste disbudding, using local anaesthesia with and without analgesia, on behaviour and cortisol of calves

    | Contributor(s):: Stilwell, G., Carvalho, R. C. de, Lima, M. S., Broom, D. M.

    We looked at the effects of local anaesthesia with or without a non-steroidal-anti-inflammatory analgesic drug (flunixin-meglumine) on behaviour and plasma cortisol after caustic paste disbudding of 1-month-old calves: at 15 min, 1, 3, 6 and 24 h (Experiment 1; n=32); at 10, 30 and 50 min...

  9. Effects of feed-back from the nest on maternal responsiveness and postural changes in primiparous sows during the first 24 h after farrowing onset

    | Contributor(s):: Pedersen, L. J., Damm, B. I., Marchant-Forde, J. N., Jensen, K. H.

    In order to elucidate whether feed-back from a farrowing nest affects the sows' activity level and responsiveness to piglets during the first 24 h after the onset of parturition, 18 primiparous Landrace x Yorkshire sows were given the opportunity to build a farrowing nest of peat, straw and...

  10. Evidence of a limited role for prolactin in the preparturient activity of confined gilts

    | Contributor(s):: Rushen, J., Robert, S., Farmer, C.

    To investigate the role of peripheral prolactin in stimulating the preparturient activity of pigs, 12 cross-bred gilts housed in standard farrowing crates either received orally 10 mg of bromocriptine three times per day from day 110 of gestation or served as controls. Jugular blood samples were...

  11. Quantifying aspects of young horses' temperament: consistency of behavioural variables

    | Contributor(s):: Visser, E. K., Reenen, C. G. van, Hopster, H., Schilder, M. B. H., Knaap, J. H., Barneveld, A., Blokhuis, H. J.

    The aim of the present work was to measure individual variation and consistency of behavioural variables, related to temperament, in young horses of the same breed and age, and reared under controlled housing conditions and management. A total of 41 Dutch Warmblood horses were tested at 9, 10, 21...

  12. Sow behaviour towards humans during standard management procedures and their relationship to piglet survival

    | Contributor(s):: Lensink, B. J., Leruste, H., Bretagne, T. de, Bizeray-Filoche, D.

    Piglet crushing remains a major problem in pig production and is partly related to sow behavioural traits. The sows' responses to the presence of humans around farrowing could partly contribute to piglet crushing through increased reactivity and getting up and lying down behaviour. The aim of...

  13. Tail posture predicts tail damage among weaned piglets

    | Contributor(s):: Zonderland, J. J., Riel, J. W. van, Bracke, M. B. M., Kemp, B., Hartog, L. A. den, Spoolder, H. A. M.

    Tail biting in pigs is a widespread behavioural vice with significant animal welfare and economic consequences. All too often, tail biting is not diagnosed nor dealt with until tail damage is present. To effectively reduce the negative effects of tail biting, it must be diagnosed in an early...

  14. The behaviour of broiler chickens and its modification by lameness

    | Contributor(s):: Weeks, C. A., Danbury, T. D., Davies, H. C., Hunt, P., Kestin, S. C.

    The behaviour of 6 replicates of approx. 100 broilers (Ross 308) obtained from commercial farms, fed ad-libitum and housed on a 23-h light:1-h dark schedule at 20 lx was observed using scan sampling. Comparisons were made between sound birds and those of varying degrees of lameness between 39 and...

  15. The effects of air transport on the behaviour and heart rate of horses

    | Contributor(s):: Stewart, M., Foster, T. M., Waas, J. R.

    Although many horses (Equus caballus) travel by air, there is little information on the effect of this type of transport on their physiology and behaviour. This study monitored the behaviour and heart rate of horses during air transport to identify events that might be stressful and to compare...

  16. Urinary behavior of female domestic dogs (Canis familiaris): influence of reproductive status, location, and age

    | Contributor(s):: Wirant, S. C., McGuire, B.

    The urinary behaviour of adult domestic dogs (Canis familiaris) is sexually dimorphic with respect to the posture (males lift a leg and females squat), frequency of urination (males urinate more frequently than females), and tendency to direct urine at specific objects in the environment (males...

  17. Urine marking by free-ranging dogs (Canis familiaris) in relation to sex, season, place and posture

    | Contributor(s):: Pal, S. K.

    Carnivores use various scent-marking methods. Observations on the scent marking by urination of 16 free-ranging dogs from two neighbouring groups were recorded in the town of Katwa, West Bengal, India. The frequency of urine marking was higher in males than in females. The seasonal mean...

  18. Assessing undesired aggression in military working dogs

    | Contributor(s):: Haverbeke, A., Smet, A. de, Depiereux, E., Giffroy, J. M., Diederich, C.

    The present study assesses the reactions of military working dogs (MWDs) to potential aggression-inducing stimuli. A standardized aggression test was conducted on the dogs (n=31) and their behaviour was recorded on videotape and subsequently analyzed. The results of the test were compared with...

  19. Behaviour of fast- and slow growing broilers to 12 weeks of age and the physical consequences

    | Contributor(s):: Bokkers, E. A. M., Koene, P.

    Behaviour of broilers up to 6 weeks of age has been studied extensively, but little is known what happens after 6 weeks. Insight in the behavioural abilities after 6 weeks may also yield insight in the period before 6 weeks as the disbalance between motivation and physical abilities is more...

  20. Impact of riding in a coercively obtained Rollkur posture on welfare and fear of performance horses

    | Contributor(s):: Borstel, U. U. von, Duncan, I. J. H., Shoveller, A. K., Merkies, K., Keeling, L. J., Millman, S. T.

    Rollkur, the usually coercively obtained hyperflexion of the horse's neck, is employed as a training method by some dressage riders; however, its use is controversial as it may cause discomfort and adversely affect the horse's welfare. The objectives of this study were to determine: (1)...
