  1. Interaction between sows’ aggressiveness post mixing and skin lesions recorded several weeks later

    | Contributor(s):: Tönepöhl, Björn, Appel, Anne K., Voß, Barbara, König von Borstel, Uta, Gauly, Matthias

    Group housing of pigs leads inevitably to more or less serious agonistic interactions during the establishment of the social rank order of the group. In order to reduce the number of severe agonistic interactions and thus the negative effects on well-being and performance, the use of genetic...

  2. 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...

  3. Behaviour, wounds, weight loss and adrenal weight of rabbit does as affected by semi-group housing

    | Contributor(s):: Buijs, S., Maertens, L., Hermans, K., Vangeyte, J., Tuyttens, F. A. M.

    Group housing is often assumed to improve the welfare of gregarious species. Whether this is actually the case depends on the advantages (e.g. more opportunity for social and locomotor behaviour) and disadvantages (e.g. increased fighting and wounding) induced by the specific housing type. We...

  4. Straw applications in growing pigs: effects on behavior, straw use and growth

    | Contributor(s):: Bulens, A., Beirendonck, S. van, Thielen, J. van, Buys, N., Driessen, B.

    The short-term effects of four straw applications on pigs housed on slatted floors were investigated to determine differences in behavior, straw use and growth. Both the type of straw used and the design of the application might influence the attractiveness and effectiveness of the applications....

  5. Analysis of the phenotypic link between behavioural traits at mixing and increased long-term social stability in group-housed pigs

    | Contributor(s):: Desire, S., Turner, S. P., D'Eath, R. B., Doeschl-Wilson, A. B., Lewis, C. R. G., Roehe, R.

    Mixing of growing pigs results in aggressive contests between group members. As aggression serves to establish dominance relationships, it is possible that increased initial aggression may facilitate the formation of social hierarchies. The objective of the study was to investigate whether there...

  6. Effect of feed allowance at pasture on lying behaviour and locomotory ability of dairy cows

    | Contributor(s):: O'Driscoll, K., Lewis, E., Kennedy, E.

    In temperate climates where cows are primarily managed at pasture shortages of grass could result in nutritional deficits for the cow and thus pose a challenge to her welfare. This study investigated the effect of daily herbage allowance (DHA) on dairy cow lying behaviour, locomotory ability, and...

  7. Canine scent detection of human cancers: a review of methods and accuracy

    | Contributor(s):: Moser, E., McCulloch, M.

  8. Development and testing of an on-farm welfare assessment protocol for dairy goats

    | Contributor(s):: Muri, K., Stubsjoen, S. M., Valle, P. S.

  9. Assessing the effects of a chronic stressor, stocking density, on welfare indicators of juvenile African catfish, Clarias gariepinus Burchell

    | Contributor(s):: Nieuwegiessen, P. G. van de, Boerlage, A. S., Verreth, J. A. J., Schrama, J. W.

    Fish welfare is an area of increasing interest and stocking densities used in commercial aquaculture have been highlighted as a subject of specific welfare concern. The present study assessed how stocking density affects growth performance (final body weight, SGR, FCR), physiological (plasma...

  10. Diurnal rhythm of feather pecking behaviour and condition of integument in four strains of loose housed laying hens

    | Contributor(s):: Kjaer, J. B.

    2400 chickens from 4 commercial strains, Lohmann Selected Leghorn (LSL), Norbrid 41 (NB), Lohmann Brown (LB) and ISA Brown (ISA) were reared and kept in aviary systems. Feather pecking behaviour was recorded by time sampling from video recordings at 38 weeks of age and condition of plumage, keel...

  11. Effect of a synthetic plate in the lying area on lying behaviour, degree of fouling and skin lesions at the leg joints of finishing pigs

    | Contributor(s):: Savary, P., Gygax, L., Wechsler, B., Hauser, R.

    Flooring type may have a major influence on thermoregulatory behaviour in finishing pigs, as well as on the occurrence of skin lesions at their leg joints and pen fouling. In this study, we compared the lying behaviour, pen fouling and the occurrence of leg lesions in finishing pigs kept in...

  12. Effects of early contact between non-littermate piglets and of the complexity of farrowing conditions on social behaviour and weight gain

    | Contributor(s):: Kutzer, T., Bunger, B., Kjaer, J. B., Schrader, L.

    In this study we tested if contact possibilities between non-littermate piglets and complexity of farrowing conditions affect the pre- and post-weaning behaviour, weight gain and skin lesions of piglets. Suckling sows were either kept in a group housing system (GH), in a single pen loose housing...

  13. Feather eating in individually caged hens which differ in their propensity to feather peck

    | Contributor(s):: McKeegan, D. E. F., Savory, C. J.

    Two experiments examined the responses of 16 individually caged laying hens to the presentation of feathers plucked from dead birds of the same genetic line. In the first experiment, hens known from a previous experiment to be either feather peckers or non-peckers (8 of each) were tested for...

  14. 'Subordination style' in pigs? The response of pregnant sows to mixing stress affects their offspring's behaviour and stress reactivity

    | Contributor(s):: Ison, S. H., D'Eath, R. B., Robson, S. K., Baxter, E. M., Ormandy, E., Douglas, A. J., Russell, J. A., Lawrence, A. B., Jarvis, S.

    In various mammals stress during gestation can result in long term effects on the behaviour and physiology of the offspring. The aims of this study were (i) to characterise individual variation among primiparous sows (gilts) in their behavioural and physiological response to a commercially...

  15. Assessment of animal welfare in 80 dairy cow herds in cubicle housing # animal health and other animal-related parameters

    | Contributor(s):: Rouha-Mulleder, C., Palme, R., Waiblinger, S.

    Introduction: With growing concerns about farm animal welfare (e.g. by consumers; WILDNER, 1998), knowledge about the actual situation with regard to animal welfare on farms is important. Valid assessment of animal welfare requires the use of animal-based parameters, while environmental...

  16. Effects of Burdizzo castration on CO<sub>2</sub>; laser induced thermal nociception of Holstein-Friesian calves of different ages

    | Contributor(s):: Ting, S. T. L., Earley, B., Veissier, I., Gupta, S., Crowe, M. A.

    The objective was to investigate the effects of Burdizzo castration on the thermal nociception (stress-induced hypoalgesia) of Holstein-Friesian bull calves of different ages. Calves castrated at 5.5 mo of age were compared with either intact calves of the same age, or calves castrated at 1.5,...

  17. Effects of space allowance on the welfare of dry sows kept in dynamic groups and fed with an electronic sow feeder

    | Contributor(s):: Remience, V., Wavreille, J., Canart, B., Meunier-Salaun, M. C., Prunier, A., Bartiaux-Thill, N., Nicks, B., Vandenheede, M.

    The minimal legal space allowance for grouped pregnant sows in the EU is 2.25 m2/sow. The effect of higher space per animal on agonistic behaviour and social stress of animals living in dynamic groups is not known. Two groups of 34 pregnant Belgian Landrace sows were housed in two pens of...

  18. The accumulation of skin lesions and their use as a predictor of individual aggressiveness in pigs

    | Contributor(s):: Turner, S. P., Farnworth, M. J., White, I. M. S., Brotherstone, S., Mendl, M., Knap, P., Penny, P., Lawrence, A. B.

    Post-mixing aggression in commercially housed pigs can be intense and often results in the accumulation of skin lesions. The number of lesions (lesion score, LS) has often been used as a proxy indicator of post-mixing aggression. There has been no previous attempt to quantify the role of...

  19. Observations on behaviour and skin damage of slaughter pigs and treatment during lairage

    | Contributor(s):: Geverink, N. A., Engel, B., Lambooij, E., Wiegant, V. M.

    Slaughterhouse husbandry practice, agonistic behaviour in groups of pigs, indices of skin damage following slaughter (recorded on a relative scale of 1-4 where 4 indicates severe damage) were studied in 5 Dutch and 4 Belgian abattoirs. Variation in slaughterhouse husbandry practice was...

  20. Comparisons of damaging feather pecking and time budgets in male and female turkeys of a traditional breed and a genetically selected male line

    | Contributor(s):: Busayi, R. M., Channing, C. E., Hocking, P. M.

    Feather and skin pecking leading to feather loss and tissue damage is a welfare problem in commercial turkeys. A factorial experiment was designed to compare a line of unselected turkeys that previously did not exhibit this behaviour with a genetically selected male line with a propensity for...
