  1. 'Bling with bite' - the rise of status and weapon dogs

    Contributor(s):: Harding, S.

  2. A case control study of on-farm risk factors for tail biting in pigs

    Contributor(s):: Moinard, C., Mendl, M., Nicol, C. J., Green, L. E.

  3. A note on eating behaviour of dairy cows at different stocking systems - diurnal rhythm and effects of ambient temperature

    Contributor(s):: Taweel, H. Z., Tas, B. M., Smit, H. J., Tamminga, S., Elgersma, A.

    This experiment was aimed at studying the diurnal rhythm of dairy cows eating behaviour at different stocking systems, and quantifying the effect of daily ambient temperature on this diurnal rhythm. In two experiments carried out in the summer of 2003 in The Netherlands, eight dairy cows were...

  4. A note on the time budget and social behaviour of densely housed horses: a case study in Arab breeding mares

    Contributor(s):: Benhajali, H., Richard-Yris, M. A., Leroux, M., Ezzaouia, M., Charfi, F., Hausberger, M.

    We observed a high-density herd (200 mares/ha) of 44 Arab breeding mares, while in a bare paddock in Tunisia. Twenty-minute animal focal samples and scan sampling were used to determine the time budget of the mares during the period from 9 a.m. to 3 p.m. and study their social behaviour. The data...

  5. Agonistic behaviour, skin lesions and activity pattern of entire male, female and castrated male finishing pigs

    Contributor(s):: Bunger, B., Schrader, L., Schrade, H., Zacharias, B.

    Fattening of intact boars is the least invasive alternative to the detrimental welfare effects of surgical castration of piglets. However, beside problems such as boar taint the divergent agonistic and sexual behaviour of boars may impair the pigs' welfare during fattening. To evaluate the effect...

  6. Application of the Welfare QualityReg. protocol at pig slaughterhouses

    Contributor(s):: Dalmau, A., Temple, D., Rodriguez, P., Llonch, P., Velarde, A.

    The objective of the present study was to assess the sensitivity and feasibility of the Welfare QualityReg. (WQ) protocol for finishing pigs in 10 Spanish slaughterhouses. Sensitivity refers to the ability of the WQ assessment system to discriminate between slaughter conditions whilst feasibility...

  7. Behaviour of growing rabbits under various housing conditions

    | Contributor(s):: Princz, Z., Zotte, A. D., Radnai, I., Biro-Nemeth, E., Matics, Z., Gerencser, Z., Nagy, I., Szendro, Z.

    The aim of this research was to assess the effects of environmental variables (group size, stocking density, floor type, environmental enrichment) on behaviour - as a welfare indicator - of growing rabbits. Two experiments were carried out with Pannon White rabbits. In experiment 1, 5-week-old...

  8. Behavioural and physiological responses of suckling lambs to transport and lairage

    | Contributor(s):: Ibanez, M., Fuente, J. de la, Thos, J., Gonzalez de Chavarri, E.

    The effects on suckling lambs of two stocking densities during transport (high stocking density: eight lambs per m2; low stocking density: four lambs per m2) and two periods of lairage before slaughter (1.5 and 3 h) were studied. The behaviour of lambs transported for short-duration journeys at...

  9. Behavioural effects of social mixing at different stocking densities in prepubertal lambs

    | Contributor(s):: Ruiz-de-la-Torre, J. L., Manteca, X.

    The behavioural effects of stocking density and mixing individuals from 2 different flocks were studied in 80 prepubertal lambs of about 20 kg body weight kept at either low (1 lamb/m) or high (3.3 lambs/m) stocking densities, similar to conditions experienced during transport. At both densities,...

  10. Crowding phenomena in dairy cows as related to available idling space in a cubicle housing system

    | Contributor(s):: Metz, J. H. M., Mekking, P.

    The behaviour of 15 cows in a cubicle stable was recorded for periods of 3 wk with either a small or large idling area available. The highest frequency of aggressive interactions occurred in the small idling area, although the incidence of aggression decreased over time. Locomotion was seen most...

  11. Diet preference for grass and legumes in free-ranging domestic sheep and cattle: current theory and future application

    | Contributor(s):: Rutter, S. M.

    This paper reviews the current theory and potential practical applications of research on the diet preference for grass and legumes in grazing domestic sheep and cattle. Although much of this work has focussed on grass and clover as a model system, it has wider theoretical implications and...

  12. Effect of cage height on the welfare of growing rabbits

    | Contributor(s):: Princz, Z., Radnai, I., Biro-Nemeth, E., Matics, Z., Gerencser, Z., Nagy, I., Szendro, Z.

    The objective of this study was to analyse the preference of rabbits for cages of various heights, their production and occurrence of ear lesions. Experiments were conducted at the University of Kaposvar with Pannon White rabbits. In experiments 1 and 2 (preference test) growing rabbits (n=112) -...

  13. Effect of stocking density on the short-term behavioural responses of dairy cows

    | Contributor(s):: Hill, C. T., Krawczel, P. D., Dann, H. M., Ballard, C. S., Hovey, R. C., Falls, W. A., Grant, R. J.

    The objective of this research was to measure the effects of increased stocking density of stalls and headlocks on the short-term behavioural responses of lactating Holstein cows. Multiparous (n=92) and primiparous (n=44) cows were assigned to four pens of 34 cows each and stocking densities...

  14. Effects of composition and density of the group on the performance, behaviour and age at puberty in swine

    | Contributor(s):: Clark, J. R., Bell, R. W., Tribble, L. F., Lennon, A. M.

    218 crossbred pigs (Duroc-Hampshire-Landrace-Yorkshire) were assigned to a 2 x 3 factorial experiment, the factors being group composition and density. The group-composition factor consisted of pigs not re-aggregated (group 1), re-aggregated below the median body weight (group 2), and...

  15. Effects of confinement on social interaction patterns in dry sows

    | Contributor(s):: Jensen, P.

    Studies were carried out in 3 different herds, representing 3 different housing systems. In the first system (de-confinement), the animals were housed in groups of 5, with individual feeding stalls, a common dunging area and a common lying box (net floor area, 3.04 msuperscript 2/sow), in the...

  16. Effects of density and cage size on stress in domestic cats ( Felis silvestris catus ) housed in animal shelters and boarding catteries

    | Contributor(s):: Kessler, M. R., Turner, D. C.

    The influence of density and floor area on stress and the adaptation process of cats in animal shelters and boarding catteries was investigated. 63 rescued cats were observed on 113 days in a shelter at group densities of 0.3-0.9 animals/msuperscript 2. In addition, 49 rescued cats were observed...

  17. Effects of density on displacement, falls, injuries, and orientation during horse transportation

    | Contributor(s):: Collins, M. N., Friend, T. H., Jousan, F. D., Chen, S. C.

    30 mares and 29 geldings were used to determine density effects on displacement (distance moved during a stop), falls, injuries and orientation using a single-deck, open-topped commercial semi-trailer. Each horse was assigned to 1 of 2 treatments: high density (1.28 msuperscript 2/horse with 14...

  18. Effects of density, season and weather on use of an altitudinal gradient by sheep

    | Contributor(s):: Mysterud, A., Iversen, C., Austrheim, G.

    The distribution of high-quality forage is an important determinant for foraging patterns of ruminants. It has been suggested that herbivores should gradually increase the use of higher altitudes as new, high-quality forage emerges. Further, the ideal-free distribution (IFD) theory predicts a...

  19. Effects of social environment on welfare status and sexual behaviour of female pigs. I. Effects of group size

    | Contributor(s):: Barnett, J. L., Hemsworth, P. H., Winfield, C. G., Hansen, C.

    The study examined the effects of housing 24 adult female pigs in groups of 2, 4 or 8 with a space allowance of 1.4msuperscript 2 per pig on welfare status, as indicated by plasma free-corticosteroid concentrations and behaviour patterns, and sexual behaviour. Housing gilts in pairs resulted in...

  20. Effects of social environment on welfare status and sexual behaviour of female pigs. II. Effects of space allowance

    | Contributor(s):: Hemsworth, P. H., Barnett, J. L., Hansen, C., Winfield, C. G.

    This study examined the effects of housing groups of adult female pigs (6 pigs per group) with a space allowance of 1, 2 or 3 msuperscript 2 per pig on sexual behaviour and welfare status, determined by plasma free-corticosteroid concentrations. A lower percentage of gilts was detected in oestrus...
