  1. Individual variation and consistency in piglet behaviour

    Contributor(s):: Jensen, P., Forkman, B., Thodberg, K., Koster, E.

    The behaviour of 42 piglets from 13 litters was recorded immediately after birth and after suckling when the piglets were 16-24 h and 3 weeks old; the piglets were undisturbed during the behaviour recordings which lasted 1 h and 16 min, respectively. At 3 weeks of age, piglets were moved to a...

  2. Individual variation in the behaviour of pigs - noise or functional coping strategies?

    Contributor(s):: Jensen, P.

  3. Stimuli-related variation in urination frequency of female white-tailed deer during the estrous cycle

    Contributor(s):: Gassett, J. W., Osborn, D. A., Rickard, J. K., Marchinton, R. L., Miller, K. V.

    Variations in urination frequency of female white-tailed deer (Odocoileus virginianus) that appeared to be dependent on stage of the oestrous cycle and type of disturbance stimuli were observed, and possible causes for this potential chemosensory behaviour were evaluated. Eight does were exposed...

  4. 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...

  5. Leaving home: a study of laboratory mouse pup independence

    Contributor(s):: Bechard, A., Mason, G.

    Juvenile wild house mice leave their mothers at 8 weeks (+). In contrast, laboratory strains of mice (lab mice) are typically 'weaned' at postnatal day (PND) 21. Lab mice might mature faster than their wild forebears; but if they do not, standard laboratory weaning likely involves...

  6. Variation in maternal behaviour and production of sows in integrated loose housing systems in Norway

    Contributor(s):: Boe, K.

    In studies of pig production data on 15 farms, the number of liveborn piglets per litter was somewhat lower and the losses from farrowing to weaning slightly higher in than the average of Norwegian herds. Maternal behaviour was studied on 9 of the farms. The time the sow spent with her piglets...

  7. Clinical pathology and cardiovascular parameters are not influenced by housing rats under increased environmental complexity

    Contributor(s):: Mikkelsen, L. F., Sorensen, D. B., Krohn, T., Lauritzen, B., Dragsted, N., Hansen, A. K., Ottesen, J. L.

    Since the release of the revised Appendix A from the Council of Europe for housing of laboratory animals there have been claims that laboratory animals should be housed under more complex conditions; known popularly as enrichment. A number of studies have expressed concerns that this may increase...

  8. Factors associated with in-transit losses of fattening pigs

    Contributor(s):: Dewey, C. E., Haley, C., Widowski, T., Poljak, Z., Friendship, R. M.

    In-transit losses (ITL) in fattening pigs refers to mortality occurring after having left the farm but prior to stunning at the abattoir. The purpose of this observational study was to identify the associations between environmental and truck temperatures, distances travelled, feed withdrawal,...

  9. Farm managers underestimate lameness prevalence in Czech dairy herds

    Contributor(s):: Sarova, R., Stehulova, I., Kratinova, P., Firla, P., Spinka, M.

    Lameness is one of the most serious health and welfare problems faced by dairy cattle. The aim of this study was to assess how aware Czech farm managers were of this problem. The project was carried out on 14 Czech dairy farms. The proportion of lame cows observed (ie prevalence of moderate and...

  10. Measuring fearfulness of hens in commercial organic egg production

    Contributor(s):: Hegelund, L., Sorensen, J. T.

    To evaluate agreement between flock-based fear tests used in welfare assessments of laying hens in commercial organic farms, three tests were applied in 27 flocks of layers. Tests were performed at 35 and 55 weeks of age and were based on the concepts of 'novel object', 'sudden sound' and two...

  11. Perioperative stress response in dogs undergoing elective surgery: variations in behavioural, neuroendocrine, immune and acute phase responses

    Contributor(s):: Siracusa, C., Manteca, X., Ceron, J., Martinez-Subiela, S., Cuenca, R., Lavin, S., Garcia, F., Pastor, J.

    The aim of this trial was to describe the behavioural, neuroendocrine, immune and acute phase stress responses in dogs undergoing elective surgery in normal, clinical practice conditions. Sixteen dogs were submitted to elective orchiectomy or ovariohysterectomy using a standardised surgical...

  12. Relation between parity and feed intake, fear of humans and social behaviour in non-lactating sows group-housed under various on-farm conditions

    Contributor(s):: Kongsted, A. G., Hermansen, J. E., Kristensen, T.

    The number of group-housed, non-lactating sows is increasing rapidly in Europe. However, systematic information of the between-sow variation in animal welfare related factors under various on-farm conditions is lacking. Indicators of feed intake, fear of humans and social behaviour in...

  13. Relationships between multiple welfare indicators measured in individual chickens across different time periods and environments

    Contributor(s):: Nicol, C. J., Caplen, G., Edgar, J., Richards, G., Browne, W. J.

    The assessment of animal welfare requires the collection of multiple indicators of welfare but quantification of their associations in different contexts is lacking. Previous studies have examined correlations between a few indicators, but not relationships between many different indicators, or...

  14. Sensory development in puppies ( Canis lupus f. familiaris ): implications for improving canine welfare

    Contributor(s):: Jones, A. C.

    Despite an auspicious start from which lasting theories were generated (eg critical periods hypothesis, Scott & Marston 1950), and despite recent modern technology enabling biological investigations of sensory development (eg EEG, fMRI), in the last fifty years little attention has been devoted...

  15. The influence of losing or gaining access to peat on the dustbathing behaviour of laying hens

    Contributor(s):: Wichman, A., Keeling, L. J.

    This study investigated the influence of being reared with or without access to peat as well as the effects of losing or gaining substrate access on the dustbathing behaviour of young, domestic fowl (Gallus gallus domesticus). There were four treatments, based on the period of time chicks had...

  16. Training laboratory-housed non-human primates, part 1: a UK survey

    Contributor(s):: Prescott, M. J., Buchanan-Smith, H. M.

    Training using positive reinforcement is increasingly recognised as a valuable tool for the humane and effective management and use of laboratory-housed non-human primates. We utilised a mixed-mode questionnaire to survey use of training and other learning processes (socialisation, habituation...
