  4. Immunocastration with Improvac™ reduces aggressive and sexual behaviours in male pigs

    | Contributor(s):: Brewster, Veronica, Nevel, Amanda

    Surgical castration of male pigs is a common practice to reduce the risk of boar taint, an accumulation of pheromones in the muscles of pigs giving an undesirable odour to the pork of entire boars. Castration is not widely practiced in the UK for welfare reasons and indeed, assurance schemes...

  5. Automatic registration of grazing behaviour in dairy cows using 3D activity loggers

    | Contributor(s):: Nielsen, Per Peetz

    Automated systems for monitoring behaviour of cows within dairy production are increasing and developments in technology provide new opportunities in this area. This study aimed to validate the use of a 3D activity logger (HOBO® Pendant G Data Logger), that registers the cow's head positions...

  6. Automated measurement of acceleration can detect effects of age, dehorning and weaning on locomotor play of calves

    | Contributor(s):: Rushen, Jeffrey, de Passillé, Anne Marie

    Play may be a behavioural indicator of positive emotions in young animals, but in calves spontaneous play is time consuming to record. We examined whether measures of acceleration of calves in a large enclosure could detect effects on play running of age, dehorning and weaning off milk. Holstein...

  7. Identification and development of measures suitable as potential breeding traits regarding dairy cows' reactivity towards humans

    Full-text: Available

    | Contributor(s):: Ebinghaus, A., Ivemeyer, S., Rupp, J., Knierim, U.

    Behavioural indicators of the human-animal relationship (HAR) are predominantly used in animal welfare science. However, the reactivity of dairy cows - as part of the HAR - is also of interest in the context of dairy breeding, due to its estimated moderate heritability. The avoidance distance...

  8. Neural mechanisms underlying human-animal interaction: An evolutionary perspective

    | Contributor(s):: Carter, C. Sue, Porges, Stephen W., Freund, Lisa S., McCune, Sandra, Esposito, Layla, Gee, Nancy R., McCardle, Peggy

  9. Hippotherapy acute impact on heart rate variability non-linear dynamics in neurological disorders

    | Contributor(s):: Cabiddu, R.

  10. Validation of HOBO Pendant data loggers for automated step detection in two age classes of male turkeys: growers and finishers

    | Contributor(s):: Dalton, H. A., Wood, B. J., Dickey, J. P., Torrey, S.

    Activity levels can be used as a predictor of health status, physical condition, feed efficiency, and coping style in animals. Small, portable data loggers have been validated as an inexpensive and effective alternative to video or live observation for automated activity detection in several...

  11. Can automated measures of lying time help assess lameness and leg lesions on tie-stall dairy farms?

    Full-text: Available

    | Contributor(s):: Charlton, Gemma L., Bouffard, Veronique, Gibbons, Jenny, Vasseur, Elsa, Haley, Derek B., Pellerin, Doris, Rushen, Jeffrey, de Passillé, Anne Marie

    The time that dairy cows spend lying down is an important measure of their comfort and lameness and injuries to hocks and knees are associated with alterations in lying time. We examined whether automated measures of lying time could identify cows and farms with problems of lameness or leg...

  12. Does temperament affect learning in calves?

    | Contributor(s):: Webb, L. E., Reenen, C. G. van, Jensen, M. B., Schmitt, O., Bokkers, E. A. M.

    The aim of the study was to investigate how temperament affects learning ability in calves. Nine two-month-old Holstein-Friesian bull calves were subjected to four challenge tests: novel object (NOT), novel environment (NET), social isolation (SIT), and social isolation with a novel environmental...

  13. An initial investigation into the effects of isolation and enrichment on the welfare of laboratory pigs housed in the PigTurn system, assessed using tear staining, behaviour, physiology and haematology

    | Contributor(s):: DeBoer, S. P., Garner, J. P., McCain, R. R., Lay, D. C., Jr., Eicher, S. D., Marchant-Forde, J. N.

    In some parts of the world, the laboratory pig ( Sus scrofa) is often housed in individual, sterile housing which may impose stress. Our objectives were to determine the effects of isolation and enrichment on pigs housed within the PigTurn - a novel penning system with automated blood sampling -...

  14. 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-...

  15. The effect of nursing on the cow-calf bond

    | Contributor(s):: Johnsen, J. F., Passille, A. M. de, Mejdell, C. M., Boe, K. E., Grondahl, A. M., Beaver, A., Rushen, J., Weary, D. M.

    Dairy calves are often separated from the cow soon after birth and prevented from nursing, but little is known about the effects of nursing on the development of the cow-calf bond. This study evaluated the effect of nursing on affiliative behaviours between the dam and her calf including...

  16. The power of automated behavioural homecage technologies in characterizing disease progression in laboratory mice: a review

    | Contributor(s):: Richardson, C. A.

    Behavioural changes that occur as animals become sick have been characterized in a number of species and include the less frequent occurrence of 'luxury behaviours' such as playing, grooming and socialization. 'Sickness behaviours' or behavioural changes following exposure to infectious agents,...

  17. Sociality motivation and anthropomorphic thinking about pets

    | Contributor(s):: Paul, E. S., Moore, A., McAinsh, P., Symonds, E., McCune, S., Bradshaw, J. W. S.

    Sociality motivation, the need to feel socially connected with others, has been proposed as an important determinant of individual variation in anthropomorphic thinking. Specifically, it has been suggested that people who are socially isolated or disconnected will tend to infer more human-like...

  18. Behavioral responses of silverback gorillas ( Gorilla gorilla gorilla ) to videos

    | Contributor(s):: Maloney, M. A., Leighty, K. A., Kuhar, C. W., Bettinger, T. L.

    This study examined the impact of video presentations on the behavior of 4 silverback, western lowland gorillas (Gorilla gorilla gorilla). On each of 5 occasions, gorillas viewed 6 types of videos (blue screen, humans, an all-male or mixed-sex group engaged in low activity, and an all-male or...

  19. Innovative use of an automated horse walker when breaking in young horses. (Special Issue: Equitation science.)

    | Contributor(s):: Murphy, J.

    There is an inherent element of risk associated with "backing" and riding the previously unbroken horse. If training proceeds too quickly, conflict behaviours may result from the simultaneous application of too many cues. Automated horse walkers (AHW) facilitate the exercising of several horses...

  20. Is it a good idea to train fillies and colts separately?

    | Contributor(s):: Janczarek, I., Kedzierski, W.

    This study compared the physiological response to novel situations in sex-separated and sex-mixed groups of horses, as measured by heart rate (HR). The study evaluated the possibility of training horses in a mixed-sex system. The study included 41 Purebred Arabian 21/2-year-olds during their...
